I have KOReader on Kindle. But its UI is very odd. Recently found plugins and patches. After installing a few something was causing weird errors. Gave Claude KOReader log and it found comic reader plugin to be the problem.
Then I installed a fast reader plugin, claude fixed its flashing and added more features. Being able to SSH via KOReader and letting an LLM fix or improve things is so awesome and freeing.
I really like that this exists, but I found the menus and UI to be rather non-intuitive. My main use case was to sync reading progress between my Kobo and my iPhone. I was able to do this using KOReader on the Kobo & the Readest app[1] on iPhone (also open source).
Ultimately I decided to get rid of KOReader because it felt a bit laggy. The gestures (eg: swiping up on the left side to increase frontlight brightness) didn't work well either.
I eneded up writing my own software to sync progress from Kobo to a KOReader Sync server[2] which my Readest app also connects to (love that unlike the Kindle, the Kobo is quite an open system). You can even set it up so you can SSH into it[3].
I really appreciate that KOReader is an option. On my older Kindle (first-gen Paperwhite), the default reading experience had declined until page turns take several seconds. Firmware update and factory reset wouldn't fix it. Using the default reader just wasn't a viable scenario.
I jailbroke it, launched KOReader, and it's like I have a new e-reader. The amount of customizability gets kind of in the way, but once it's set up I don't really think about it from one month to the next. I also didn't feel the need to upgrade my original install either.
Amazon bricked the first gen paperwhite, so I went on a similar journey. I started out making a single rust app on it, then went down the rabbit hole of trying to replace the shell/launcher. https://github.com/justinledwards/ferrink-home-assistant and "ferrink" is the launcher. It is pretty snappy on the paperwhite for what it is.
I tried to set up KOReader multiple times and always got stuck figuring out where all the settings are and how exactly they work. It seems very complete, but I'm just too dumb to actually use it.
I went through the same on my 10-inch Android tablet. The key is just sticking with it long enough to get it set up for your needs and prefs. I'm glad I did because it's really great. While the docs are quite good, if you get stuck just use an LLM. Once you get it configged, you won't be using the UI much.
KOR is both complete and very capable. It can very probably do everything you'll ever want but, as many people observe, the UI is just a bit weird. That's not to say the UI is broken or inconsistent, its simply that its approach is a little different than you'd expect. Once I got familiar with the main flow of the UI, it hasn't been an issue for my daily-use needs. If you care about flexibility, control, features and having it "your way", I think it's well worth the one-time effort to set up. It's also extremely user-moddable with Lua scripts. I use several found here: https://github.com/sebdelsol/KOReader.patches.
I also found all existing e-reader software to be lacking, and all I really wanted was a basic reader. I ended up writing my own with Rust and MyPDF (the latter doing all the heavy loading).
The hardware is great, but the software is pretty lacking. Apparently a lot of the tools out there are from folks in similar situation: had the hardware, but the software to drive it was lacking.
I installed it on my Amazon Kindle and I couldn't be happier.
It shows once again that free software is superior to proprietary software. Free software grows slowly to make users happier and not to attract them with useless features to extract more value from them.
Congratulations for this great piece of software.
I’m a heavy KOReader user and absolutely adore it, but I think it definitely trades user-friendliness for power and flexibility. The Kindle proprietary store has a far more user friendly UI imo, though it’s getting progressively worse (and the fact that kindles now default to showing you the store pisses me off to no end). KOReader plugins really close the gap though.
> I think it definitely trades user-friendliness for power and flexibility
A tale as old as time with OSS software from what I've seen. So far the only exception that I've seen of a FOSS piece of software with great UX is Blender[1]. With UX not being a first-class citizen on Linux, exposure to a solid universal tooling to create great UX also exacerbates things.
I think the issue of bad UX and OSS are comorbid because good UX needs an extremely opinionated mind at the helm and a culture of prioritizing features and saying "No, this is not important" which OSS generally lacks.
I think Libreoffice is easier to navigate than ribbon-era Office.
I think especially Gnome, but also Kde has better settings than Windows, which is spread across a new and a classical view (or more?).
I also think MacOS finder is worse than Windows/KDE/Gnome equivalents. When you strip so much away that people have to remember strange key combinations to jump/navigate to specific directories you have really gone too far.
And mobile UX (android and iphone) seem to me worse than any desktop system. Nothing is consistent (sharing data between apps), nothing ever seems settled (settings move around in the central settings apps every few releases).
We could argue in depth. Let me head it off a bit - taste is absolutely a thing, but consistency across releases is evidently a good thing unless you are constantly in a situation where your existing userbase is dwarfed by the prospective one. There’s a reason we hang on to diskette icons, don’t change from desktop to metro to ios style desktops every release and so on.
Last point: OSS software can be misguided, but it never seeks to bamboozle the user to make some corporate goal succeed. It won’t nefariously stuff files on a cloud or actively make it hard to export data or be incentivized to NOT interoperate with devices or programs shipped by competitors.
People say that and I used to agree, but honestly I use neither MS Office nor LibreOffice heavily anymore. Nowadays I can figure out what to do in MS Office very quickly but LibreOffice's menus are a confusing maze (even when switched into the more ribbon-like mode).
> So far the only exception that I've seen of a FOSS piece of software with great UX is Blender.
Most OSS software favors power users instead of total beginners. And even Blender is not a great exercise in discoverability. You need training to use it.
The stock software in Kobo and kindle can be used within minutes because they don't have a lot of features/options. And it's totally fine if that's what you need. Just like Windows 7's Notepad. But if you need more capabilities, your wish is notepad++/vim level (which does require more learning), which is what koreader is.
> Most OSS software favors power users instead of total beginners. And even Blender is not a great exercise in discoverability. You need training to use it.
I think it’s more subtle than that. I am a power user — I was compiling my Linux kernel in the 90s, I wrote my own SSH tunnel manager 20 years ago, I always fiddle with settings, etc. etc.
However, I am constantly frustrated with a lot of OSS software because it expects you to think like the developer of the tool, instead of having empathy for the user. What feels obvious to the developer of the tool (I am making up a hopefully-representative hypothetical here, but finding the change of font under “Theme” because it’s how “it looks” but finding the font size under “View” because, well, you view it) feels frustrating and nonsensical to a normal human who relates both the font and its size the same way in their mind. Again, generally — I’m making generalizations here and not calling out any specific software, but trying to illustrate the feeling that I get.
When I switched to the Mac in 2002, it is because these sorts of things made sense. Yes, there were and are frustrations because of this sort of opinionated design mentality, but I judged the benefits to outweigh the positives. Unfortunately, Apple squandered this culture and skill and nowadays I often find the platform as frustrating as OSS ones, to the point where I have switched back to 50/50 time split between platforms.
I find this is mostly just a "mindset" difference.
OSS software aligns mentally with "tool". It only exists because someone had a problem to solve, and they wanted a tool to solve it. Generally, people should expect to have to learn how to use tools. Then they solve their problem and move on. It takes effort, and the result is mastery which gives you new capabilities.
Consumer software (and especially anything ad supported or social media adjacent, and sadly in many respects, lots of modern SaaS companies) want to be as glitzy and smooth as possible, but they don't actually want you to solve your problem. Instead they'd really prefer that you simply spend as much time looking at their software as possible. So the experience can be quite pleasant, it feels nice, things feel obvious, you get the dopamine hits quick and fast. But after a while you realize you aren't actually all that productive (or even productive at all) when engaging with them. Because the goal of this software isn't to help you solve your problem. The goal is to keep your attention and extract your money. If it happens to solve your problem... sometimes that's fine, sometimes that's actually counter to the primary mission of extracting your time and money.
> The stock software in Kobo and kindle can be used within minutes because they don't have a lot of features/options.
Afaik koreader itself does not support stylus while the default reader in kobo does (somebody made a plugin lately but not sure how stable it is). Not to say that koreader is not amazing, but it does not mean that FOSS always has strictly more features. If koreader had strictly more features and I wanted some of them I would choose that. But I also right now want to use the ereader to read books and take notes, not tweak plugins and configurations. I have been in this "power user" loop where I spend more time with configuring rather than doing the thing, and I am a bit more selective with when this makes sense to me.
I love the discoverability of blender in the sense that I can hit space and start typing the name of the thing I want to do and run it from there while it shows me in what menu I could find it and what shortcut to use. And next space it remembers the last thing I ran so to repeat it its even faster.
This requires however to remember the name of the command (or parts of it). I often remember that but not where to find it or the shortcut.
It also requires that you chose the spacebar search option, which is the only correct option if you ask me. (Not a pro. Just messing around with blender sometimes.)
you will spend much MUCH more time as a power law user than as a new user, such that almost any % gain in productivity once familiar is worth almost any months of unproductivity when new.
> I think the issue of bad UX and OSS are comorbid because
I think UX is simply harder when you're not leading the user by the nose to your most profitable features, and removing or obscuring the others. Commercial UX is more akin to advertising than UX, so there's no wonder that it makes very clear the few affordances that it offers (and bizarre when it doesn't, like the "flat" period.)
The other problem with FOSS UX is that millions of dollars haven't been put into it (literally: 5 developers = 1 million dollars/year.) The wonderful benefit of FOSS UX is that you have plenty of time to learn it, because every feature is already there, no one is forcing you to upgrade, and no one is moving things around and deleting things because it is more profitable to them.
Commercial UX had better be good enough to learn basic functionality quickly, because it's going to be completely recycled every year. It also doesn't want you to learn anything too deeply, because then you might become a (gasp) "power user" and make unprofitable demands.
Imagine using the same type of software (e.g. an mp3 player) for a couple dozen years and thinking that it's a hassle to figure out how to learn it. Imagine being boiled like a frog to relearn how your mp3 player works every couple years for a couple dozen years, and dreaming you've saved some sort of time or effort. Imagine you've used mp3 players for a couple dozen years, you still don't know what an mp3 is, you don't know what a file is, and you don't know how to get your mp3s back after switching your mp3 player without rebuying them. Eventually you switch to streaming, give up making any decisions, and take whatever the marketers prefer.
I jailbroke my Kindle and moved to KOReader last year, primarily to get away from the Amazon jail. Just the bare KOReader UX was pretty utilitarian. It lacked polish for sure. I'll have to agree that, as noted elsewhere, the KOReader menus can be difficult to get a grip on.
If you're working at just the most basic level of functionality, I don't think KOReader is necessarily worse than native Kindle. The latter is hampered by being very opinionated about how you should experience it, and that includes pushing their store above the user's own library, and this is a real annoyance.
As you start to demand more capabilities they diverge more. Organizing when you've got many books on the device is clunky on both platforms, but in different ways. The native Kindle options for grouping are simple, but not necessarily easy. They're very generic, and very cumbersome to work with. Bare KOReader's support for folders makes more sense to me, and it's easier to deal with bulk books than is Kindle's.
Getting books onto Kindle is super-easy if you get them from Amazon, but complexity ramps up for other sources. Your best bet is plugging it into USB and transferring via the file system. Native KOReader add to this an OPDS capability (if your book repository supports it), which works but is less than pleasant. If you use BookOrbit as your repository, there's a plugin that gives you the remote BookOrbit UI from the Kindle, which makes things a LOT better.
I experimented with Simply UI for a bit but could never get it to work quite right. About a month ago I found Bookshelf, and this makes the UX pretty wonderful. It has a very attractive and intuitive UI. And it simplifies the interactions needed for group management a bit.
Bottom line is that KOReader + Bookshelf are, for at least a power user, a potentially far superior experience compared to baseline Kindle.
I've tried hard to make Bookshelf work for me, but I find the UI confusing, going off in unexpected directions, and it's very unintuitive. I've got SimpleUI at the moment and it's comfortable, even though the library interface is lacking.
I don't know what the situation is like for Kindle, but there are atleast two open source alternatives for Kobo. KOReader is the Swiss Army knife, Plato is easier to use.
A few people are suggesting that KOReader is symptomatic if the issues with open source software. The reality is it targets a particular group of users.
I think the only proprietary software companies with any shot at longevity are Japanese companies. First Japan leads by far the ranking of oldest companies in the world (https://en.wikipedia.org/wiki/List_of_oldest_companies). Then we have actual software like Zelda Breath of the Wild which is a technical marvel comparable to the original Rollercoaster Tycoon considering how well it runs on the severely limited architecture of the Switch.
I think this boils down to profit not being the only driving force for these companies, but prestige and a sense of duty and responsibility towards something larger and less immediate.
You're assuming long lasting soy sauce companies have anything to do with software development. Japan produces great video games despite how terrible otherwise the developer environment and culture is there and nearly all of the other software shows it.
Didn't say they are good quality, or the working environment is nice or anything, just that they have higher chances or living a long time. The reasons might not be any more or less commendable, but they are different than chasing the highest profit margin possible in the next quarter
Japanese software and software technology culture is amongst the worst in the world. They're famous for failing to adopt modern ways of working, tools and as an industry is seriously struggling. There's fantastic video in this from Asianometry: https://youtu.be/ky1nGQhHTso
> Software was not viewed so much as a product, but more like a service, similar to integration, training, and ongoing support and maintenance. It was usually sold on a time-and-materials basis, and sometimes it was just thrown in for free to sweeten the deal. The real money was in the hardware.
> Software development was considered rather low-skill work. It didn’t pay well and was viewed as a kind of clerical work. The job was simply to write software that was close enough to whatever sales had promised the client while they were out drinking last week.
Until the threat of anti-trust against IBM, and the latter's decision to “unbundle” its software from its hardware, in 1969. There had been proprietary software before that, but very little horizontal software (OSs, development tools, etc.) Autoflow's flowchart generator was a rare example of this.
Wouldn't wanna live there permanently. Wouldn't want to have been born Japanese. But my god the products and services are head and shoulders above my baseline expectations; it's simply nicer.
I have always found the adoption loophole to maintaining a family business hilariously smart.
I also understand why it’s not something common outside of Japan. Selling your family name in exchange for (maybe) keeping your business alive is distasteful at best.
Bro has never played the thousands of shitty visual novels. Hell even from software games, which are beautifully well designed, are technically embarrassing
> Breath of the Wild which is a technical marvel comparable to the original Rollercoaster Tycoon considering how well it runs on the severely limited architecture of the Switch.
What? It can’t even maintain a stable 30fps on its own target hardware. That’s not an example is point to for something running “well.”
Yeah, it's genuinely my favorite game of all time but to compare it to Rollercoaster Tycoon as "a technical marvel" is doing a massive disservice to Chris Sawyer.
I've been a Kindle user since way back in 2010 with a Kindle 3G. I had a pretty huge amount of money invested into a library of books on Kindle. I installed koreader on my paperwhite earlier this year and haven't looked back. Even if it weren't for the limitations put on the walled garden for books in the kindle ecosystem, just the software upgrade alone feels great. When you hit buttons in koreader it actually responds in less than a second. I hadn't even realized how frustrating the UX of the kindle OS was until I realized the hardware was capable of feeling snappy.
There's obviously a lot you need to provide yourself that Amazon gives "for free" with the Kindle ecosystem, but using koreader with OPDS and kosync for synchronizing progress across devices, I'm very happy to be just buying DRM-free books elsewhere and hosting a small OPDS+kosync server on my home server. Installing tailscale on my kindle makes it so I can even fetch books/sync progress when I'm away from home without needing to expose my book server to the internet.
As someone who thought the same (stock was enough for me) until I had some free time and switched, here are some things I'm really enjoying, in no particular order:
- Format support: EPUB, CBR/CBZ (comics, graphic novels), PDF
- Dark mode
- Fully programmable gestures and shortcuts
- Automatically syncs with my readeck instance (think readitlater/instapaper) to dowload the articles I save for example here on HN
- Calibre integration over wifi
- RSS/Atom
- Custom dictionaries
If you are into manga, there is an extension for directly downloading them on the device
Because most of the page is dark, with light only coming from the text, the total light emitted is much less. That makes it less annoying to my wife, when I'm reading before going to sleep.
this is the worst kind of pedantic engineer comment that seems to infest this site. they're obviously talking about the frontlight. dark mode reflects much much less light back at the user through the lightguide because the dark bg absorbs more of the light.
If you want pedantic ridiculousness, well, notice that I never said that the e-ink emits light. It does, however reflect light back from the device's frontlight. The device taken as a system most certainly emits light, but less so when in dark mode.
I have no idea but users seem to like it despite all the ghosting.
The reason I use koreader is because it can sync my progress on disparate devices. I have a normal sized kobo and also a phone sized viwoods eink device.
In my case from different places like itch.io , smashwords.com, gumroad.com, some fundraisings that provide epubs. You also have some nice free places like standardebooks.org. Or you can sail the digital seven seas if there's no availability.
https://www.gutenberg.org/ has more books than you will be able to read in your lifetime for no cost. Some are classics for a reason, some are garbage - same as any other publisher.
There are a number of other free ebook sites out there as well.
Stuff which may be above the kindle stock features (as seen on Paperwhite 10):
- Allowing to highlight text across pages. Used to work in the past but no longer works
- Allowing exit to library from mobi files without a cold reboot of the device. Used to work, no longer works.
- Not deleting contents of my library on an update overnight? (files still on disk, metadata gone, no longer visible on Kindle)
- consistently working dictionary, offline, at least for English texts? (used to mostly work, with recent updates it is broken)
- Not getting worse on every update
- Better keyboard layout, maybe supporting smaller languages
- Not deleting purchased books remotely
- better bookmarks and navigation support. I find Kindle useless for the technical reading and learning materials, as navigation and cross-referencing is slow clunky and useless, I need paper books for that, or a computer.
- Better image display? Also hinders proper use for digesting technical content.
- Better and faster UI. I always thought the Kindle was just slow, nope, it's just really bad software
- Customise any/everything. Font size, line spacing, paragraph spacing, margins, header/footer content, the list goes on
- Ability to use things like BookOrbit (or alternatives) to manage your books and sync your progress/stats.
- LLM-integration through plugins like KOAssistant, highlight a word/phrase/passage to get it explained to you. This was invaluable for me when reading through a series from the 1950's about the late 1700's, lots of phrases I'd never heard. Many I could grasp the meaning from context but it was way more fun to hear the "why" behind the phrase. Same with historical events that I am less knowledgeable about than I wish. Let's me stay "in the book" instead of picking up my phone.
- Full control, some people don't care/need this but I love being able to SSH into my Kindle and do whatever I want. I love having my entire book reading experience end-to-end be fully open source and self-hosted.
Ability to use things like BookOrbit (or alternatives) to manage your books and sync your progress/stats
I discovered BookOrbit about two months ago. I think that it, together with the KOReader plugin that exposes the remote BO UI, may turn out to be a game changer in how I organize and access my ebook repository.
Same here, I jailbroke my kindle just 1-2 months ago (when the PW5 JB came out) and I had been using BookOrbit for only a few weeks before then. Since then I've read over 15 books and been loving BookOrbit and KOReader.
It does not have any sort of "whispersync" but, ironically?, I feel like whispersync could be recreated with things like Whisper and parsing the epub/whatever to line up progress. BookOrbit is in active development from what I can see (I'm not connected to the project, just a happy user) and it wouldn't surprise me if that was a feature in the future. It's something I've mulled over building for a while (even before Whisper).
For my Audiobooks I don't use BookOrbit because my setup is:
- Buy on Audible
- Rip DRM off
- Add to Plex
- Use Prologue (iOS only) to listen
And I freaking love that setup so I'm not looking to replace it currently.
Never updating if you don't want an update. I see no reason for my e-reader to have updates. I have a Kobo and after I updated it once about 5 years ago I haven't since because it already does everything I need it to.
Not only is it the superior piece of software, the freedom it offers by dissociating the choice of hardware from the choice of software is another example why free software and interoperability is something we should strive for.
I like the Readwise integration via plugin and the EPUB support, but for the first few days with it, I was busy understanding the menu hierarchy and trying to figure out how to match the styling and spacing of my native Kindle books. The out-of-the-box experience is unfortunately just "tasteless," and I needed some time to warm up to it.
I'm immensely thankful for koreader - it improves the reading experience so fundamentally that it literally drives my purchasing decisions. I got a remarkable 2 precisely because it was known to run it well. When I got a new kindle, I went for a refurbished one hoping it'd be one FW version behind (it was! lucky me) so I could jailbreak it immediately, and run koreader.
Which reminds me:
- I'm still a primitive user. Sync reading state, reflow, calibre link, yes, but I'm at maybe 10% of the features, might even be an overestimate. I may finally have to cave in and go through its manual
- I literally endure calibre because that's how I feed koreader. Any alternatives?
- Is there really no practical way to mark a book as read other than give it a star rating or a custom tag?
- Does anyone know of anything coming close to this experience on an iPad?
- I've never given them a cent or contributed a line of code or even filed a bug report. That changes now.
> - I literally endure calibre because that's how I feed koreader. Any alternatives?
I use USB mass storage.
In details, I configured KOReader not to start mass storage automatically, so I need two taps after connecting the USB. Then on my Linux PC, I mount the device, exec a `rsync` command, then umount.
My ebooks directory uses Git (with LFS) so I can update it from several computers. I considered switching to git-annex, instead of gitlfs+rsync, but I'm not motivated enough to change a system that works.
> - Is there really no practical way to mark a book as read other than give it a star rating or a custom tag?
There are 3 states : reading, on hold, finished. The rating is optional. A long press on a book title will give access to this states and more.
All that metadata is stored in lua data files (a bit similar to JSON). With mass storage, it's easy to read or update these files. I use "on hold" to mean "dropped" (and I hide them in the listings).
I've been messing around with this as well, and there are a few good options now, if you're willing to self-host services:
- calibre-web, as a pure web front end to the calibre db
- Calibre Web Automated, which is a rewrite of the app, with a better web UI, that is faster and adds functionality
- Grimmory, a Java-based book mgmt. app w/ a web front end too
- BookOrbit, similar to Grimmory but written in Node and seems to scale better w/ 100k+ book libraries
The better way to get books onto KOReader is via connecting to these apps' OPDS feeds. Wireless, and most of these other apps have better library organization.
Last week they released a change that put the header Strict-Transport-Security into all responses (yes, even non-HTTPS ones!). This broke not just BookOrbit, but every other app I had running on that server, because suddenly everything being served by that host refused to work without HTTPS.
I probably should have done it sooner, but I spent a big chunk of the afternoon setting up new DNS entries so I can access each app through a different hostname. That was easy enough for me, running OPNsense with my own internal DNS, but you may not have that much flexibility in your home.
I submitted an issue (see https://github.com/bookorbit/bookorbit/issues/760) and a few days later, they created a semi-fix such that the header is only sent out in secure responses. But this still has the effect of forcing every app on that server to require HTTPS.
I use BookFusion. A plugin for Calibre (which is still my central library) lets me upload chosen books to the BookFusion server, after which I download to KOReader. Using the BookFusion plugin for KOReader I can sync reading progress and annotations to back to the cloud, and read on iOS or other devices using KOReader.
> - I literally endure calibre because that's how I feed koreader. Any alternatives?
On first exposure to calibre I was put off by its weird UI and how opinionated it was about filename conventions. But I learned to accept that it's the best solution out there with the most community support, and it grew on me. There are also a few third party projects that can interact with its database.
You can use the regular Kindle viewer once you jailbroke your kindle, but KOReader has native epub and pdf support so you don't have to use a converter when uploading your books.
I did find it hard to get the bezels to be even and it still doesn't always format well depending on the book. I still kind of prefer the default viewer.
I use this plugin in KOReader which lets you download books from Z-Library within KOReader.
Another cool thing is you can use custom fonts and dictionaries. I use the OED short version and the Wikipedia one. There's built in ones that it can download but pirated ones like OED you have to upload yourself.
Unfortunately on MacOS it seems you have to use Amazon's app to access the filesystem.
Edit:
They changed it on the newer Kindle which I have.
There's open source alternatives to the send to kindle app.
> Unfortunately on MacOS it seems you have to use Amazon's app to access the filesystem.
Hmmm not really my experience, unless it's a new thing. I am still able to access it via finder. Although I need to exit KoReader first and go back to the stock UI.
>Unfortunately on MacOS it seems you have to use Amazon's app to access the filesystem.
I can recommend using a Filebrowser plugin for KOReader, that way you can access the file system over a web interface and upload that way. No cables needed or anything, quite convenient.
same experience here, jailbroken Kindle, installed KOReader, tried it and returned back to default viewer, don't exactly remember the reason, maybe overcomplicated? (especially since it's device for my kids, it doesnt have internet access, I just put there books offline)
That's very helpful, thanks! The KOreader UI is... Rough.
Love all the options, especially the ability to use folders on the device storage as the primary way to organize my books, but trying to figure out where a setting is and change it has been frustrating from the first day I installed it.
Will give the Zen UI plugin a go. Does it still support the on-device folders as the main way to navigate through your books?
KOReader is my jam! With its reflow for PDFs, I've used it on my Kindle Oasis 2 to read everything for my undergrad and graduate degree. Some years ago now, I wrote a script that converts the annotations to Obsidian [0], and then another little script to automatically keep my "Articles" folders in sync between the Kindle and my laptop.
Interesting. I generally hate proprietary software, but I've actually been really satisfied with the kindle UI. I don't use the store at all, simply email epubs to it directly. (I usually only move 1-5 books max at a given time, so this process feels really simple to me). The only adjustments I need are the text size and front light, battery life is amazing. I'm guessing this would be really useful if I had advanced needs, but for just reading epubs, kindle is a really good UI.
You must have a newer kindle. Koreader was basically my best bet once mine (2012 vintage) stopped being supported by Amazon. Native epub support plus other goodies. I’m sure you’re aware that emailing an epub to your kindle converts it to mobi before sending, potentially mucking up the formatting.
I think mine is from 2019. I didn't realise it wasn't natively displaying an epub. I haven't noticed any breaks, or maybe I attributed any errors simply to the original epub and didn't realise it was a conversion error. But also the things I read are quite plain and text heavy so perhaps that's why.
I don't like the UX but the extra controls on ebook rendering was worth the pain for me, since almost all of my time is just reading the ebook anyways.
koreader is wildly unintuitive (just try to look at battery statistics, and marvel that it's in a submenu of a submenu with only 2 items) -- but it is very powerful. once I got used to it's quirks I can't go back. Things i use all the time on my phone-sized ereader :
1. calibre sync built in
2. customised estimated time remaining/progress bar
3. custom fonts and margin support
4. hardcover.app sync
It has super useful features like the semi-auto-cropping which removes margins in PDFs (like papers or books), including unnecessary things like page numbers or similar, so that you can really maximize the size of the core content. It also has a nice chapter overview and other useful things!
Truly one of the best pieces of software I have used so far.
My only real complaint with KOReader is that the book browsing UI is file and folder based by default, while virtually all other ebook readers support some kind of cover based library view you can sort 20 different ways based on metadata rather than filenames etc.
It's not a huge issue, but I find just browsing my collection to find a read a lot more enjoyable on other ebook readers. IIRC there are plugins to add this feature, but it's not present out of the box.
On the few Kobos and jailbroken Kindles I've used it on, it also drains the battery significantly faster than the stock reader app, although not enough that I couldn't last at least a few days. On stock software I can go weeks between charges.
My experience with battery life seems to be the opposite of yours. I'm using it on a Kobo Clara BW and my battery just lasts and lasts, even with an hour or more a day of reading. I don't have any firm data on it, but I know that right now I'm at 52% battery and it's been at least a week and a half since I plugged it in anywhere.
I use KOReader a lot. After your comment, I realized file browser annoys me too. After some searching, I found an alternative view. Turns out, you can open the File browser tab, swipe down and switch "Display mode" to "Mosaic with cover images". Also seems like it's default for new versions now. This mosaic view still uses directories but it lists books as rectangles (covers) instead of lines (covers + titles), it seems more pleasant.
By the way, in the same settings I finally found how to set up KOReader to launch with a previously opened book. What a relief!
I am using koreader on my ereader and KOreader has a native support for https://wallabag.org/. They are both fantastic opensource projects, whenever I like to read a blog post I am sending them to my wallabag and therefore I can easily have them on my ereader too.
Also the fact that you can install different plugin on KOreader and customize it in a way you like is fantastic.
for example just check:
I was considering installing KOReader on my Kobo. However, I have decided that I don't want to do any tinkering with my Kobo. The entire point of my Kobo is kinda to be a distraction-free device, and messing around with installing stuff on it would ensure I would get distracted messing with the software when I should be reading or sleeping. It means I don't get to sync my progress with my phone, but I'm ok with that.
It's so funny that you say this because I 100% agree. I have a Remarkable tablet (several of them in fact) and the people on /r/remarkabletablet are always looking for ways to complicate their Remarkables with KOReader or any other number of hacks.
I want to write notes on my Remarkable and I want to read on my Kindle. They are both excellent at that right out of the box.
I'm beginning to suspect that many people actually like being distracted more than they like being distraction free!
I have this on my Amazon Kindle and I freaking LOVE it!
Paired with BookOrbit [0] and using plugins like BookShelf, BookEnds, and KOAssistant I have the best reading setup ever.
The speed of this on my Kindle is _insane_ compared to the stock software. I'm not talking about page turning, that was fine on both, but navigating menus is way faster.
It was a little finicky to configure but once I got a feel for it I didn't have a problem and 15 books read later since I installed it a few months ago and I never touch the settings.
My favorite plugins:
BookShelf: Best UI for viewing my books by author/series/etc IMHO. Much better than the Kindle default UI and much snappier
BookEnds: Configure the header and footer of each page to show what info you care about most. There are community configs you can test out easily and download right on your kindle if you like them
KOAssistant: highlight some text and throw it at an LLM with a provided prompt or your custom one. This was invaluable when reading the Hornblower series which used a lot of older english words/phrasing as well as nautical terms (which I'm completely unfamiliar with). I enjoyed the books way more since I could figure it out inside my kindle instead of constantly having to pick up my phone to look up a phrase.
BookOrbit: It provides a plugin for KOReader that syncs your progress, annotations, etc.
KOReader is table stakes for any e-reader I might consider. If my Kindle died tomorrow I'd have a Kobo or similar on it's way to me within hours. I won't use any reader that doesn't support KOReader after using it for these last few months.
If you use a Kindle, you have to jailbreak it first before installing it. There's definitely been some improvements with user experience at least with apps since I first jailbroke it. There's like an appstore with games and KOReader that I use.
love this project. i used it on my pinephone daily for at least a year: it does _everything_ you'd want and does it fast.
problem for me was that they vendor like 30 different dependencies in a totally bespoke way that's largely incompatible with any modern package management: it downloads them as part of ./configure (IIRC) and with no way for the OS to provide its own. so you're either stuck using the prebuilt releases without any means to patch/improve the software, or if you do want to make improvements then it's a full-time job to keep the package in a buildable state. in the end that was too much work for me and i switched to Foliate: it's noticeably slower (webkitgtk) and lacking, but it's way simpler to develop on.
maybe they've improved the build system in the last couple years, though a quick peek shows that the nixpkgs expression is still using the binary release. if it becomes practical to build from source in the future i will 100% switch back to it.
I use KOReader daily on my Kobo and my Boox Go 10.3 (Gen II) Lumi. I use BookFusion to sync with my iPhone. They all work great. KOReader doesn't have the most intuitive menu structure, but the plugin environment is excellent and there are several UI plugins that make using the software easier.
I finally installed this on my Kobo Libra 2. The UX is clunky but overall it works great. Very fast. Don’t need KEPUBS anymore as epubs render just as fast, where as that’s not the case on the stock software.
I finally got around to installing it as I got an xteink x3 and wanted to have cross device syncing back to my Grimmory server. Works great with OPDS and KOSync.
Although I miss using the native kobo sync where I could just add a book to my virtual shelf and have it auto sync to my device. OPDS seems very rudimentary in comparison, but it works nonetheless.
I'm wondering this too. I also thought about setting up calibre as I own a ton of drm free books and while the calibre reader itself is nice (the viewer is all I mainly use), sometimes I do find myself wanting to read on my phone while at a dr appointment or whatever
I set up KOReader with a jailbroken Kindle. DammitJeff has a good video introducing the topic. UI is definitely awkward, but it is awesome and pretty "hands off" when set up. It also has built-in support for OPDS so downloads from places like "Project Gutenberg" are a breeze. Also, if you are a homelabber with stuff like Calibre & Calibre Sync, it all works as you'd expect.
I love KOreader for the best in class type setting imho. If an e-reader can run KOreader is a purchasing factor to me for that reason. I read a lot so it matters to me how the text looks.
I have one of those Android e-books and it's nice to find good software.
Anyways I just wanted to read using the least possible resources so I'm just using a simple file manager and mupdf (in which KOreader is based). mupdf may be simple, but it's amazing.
Thanks for letting me know about mupdf! One of my favorite things about KOReader is its ability to handle humongous PDFs on extremely modest hardware; it's good to know what this ability is based on.
KOReader is one of these projects where idea is fantastic, it's impressive that it works, and the result is sufficiently quirky that I couldn't get used to it. UI is cumbersome. On kobo, it feels like it's draining battery much faster than the "regular" kobo OS. When you sync progress to KOSync with WiFi you keep getting these "Connecting to wifi" popups. And on mobile, having to use the internal keyboard feels like using the keyboard on a reader, which I do not want to.
I've never used it on Kobo (as I don't have one), but I felt that for the Kindle KOReader it was a significantly better experience than the stock experience. It's easy to sync stuff with Calibre, you can choose any TTF font, and there are more display options for reading. At least on the Kindle Paperwhite (purchased in 2015), it does not appear to significantly affect battery life.
Maybe I'm just too entrenched in the engineering space that I'm just used to "developer UI", but my wife is decidedly not a software person and she seems to like KOReader just fine.
This then allows you seamlessly switch back and forth between your e-reader and listening to the audiobook on your phone with automatic position syncing.
It's a great reader app, but as a reader of Japanese light novels it's sadly not fit for my personal purposes - last I checked vertical text is only possible in a really, _really_ hacky way (using a font that is turned sideways), and dictionary support for Japanese (or, say, Finnish with its complex lemmatization) is lacking behind browser extensions such as Yomitan, or mobile apps like Hoshi Reader that have Yomitan dictionary support.
I don't think KOReader handles fixed-size epubs terribly well too, and most of my manga (usually bought on Rakuten Kobo) comes in that format.
For reading English or native language books on non-Android e-readers it's a godsend.
I installed this the moment I got my Kobo Libra H2O. Mostly read fiction from the 1800s and early 1900s and I did not want to fight whatever proprietary software the reader came with (Kobo is probably better than the Kindle for this, but I never tried it!)
I have a problem with epubs though. This need to support every single thing under the sun makes the pipeline exceedingly complex. All you need for a vast majority of fiction is:
- headings
- paras
- emphasis (bold/italic)
- block quotes
Add simple "image" syntax to it to display maps etc from detective stories
Basically a ruthlessly cut down version of markdown.
The mini-readers from Xteink came in at the right time for such experimentation.
Kobo's reader definitely renders Epubs better than KOReader. I really only used it on my Kobo Libre H20 to download epubs from my calibre server. Now, on my Boox Go 7, KOReader beats the built-in reader hands down
Fiction from the 1800s? Now that sounds interesting. Can you name three titles that you would recommend? And: how did you get into this? Doesn’t sound like a TikTok trend, haha.
> Can you name three titles that you would recommend?
I can recommend some authors from the period: W Somerset Maugham, Thomas Hardy, Anthony Trollope, H Rider Haggard, Wilkie Collins, Saki, Maupassant, O Henry.
The list could go on forever, almost. Some books might feel dated (or too long). But that is fine.
> how did you get into this?
I started reading when I was 3-4 and never stopped. We moved to the suburbs when I was 7-8 (late 80s) and there wasn't much else to do outside of school except read. Built a physical library of close to 4,000 books along the way, but I mostly read at the computer or on e-devices
Not them, but I read Moby Dick last year. Man, I felt like I'd been lied to. It's kind of a laughing stock reference to giant old-timey books that were famous for being famous and such. So wrong! It was hilarious in parts. The narrator is a complete smartass with a strong bend to irony. I loved every bit of it, even the (in)famous chapters about whaling and knot tying and all that, which were vivid peeks into worlds I didn't know existed.
It took me some time to know my way around it, but wow. I have it configured with some plugins, like zen ui and bookshelf. I Also use BookOrbit to sync reading progress and annotations between devices. Loving it.
Great piece of software. Jailbroken my Kindle when the UI was becoming way too slow, then discovered Rakuyomi [1] and that alone is worth the jump, especially with plugins like SimpleUI to make the UX better
KOReader is so much better, including in how it renders typography and does typesetting than what ships on Kobo devices by default, it's sort of wild.
I actually made a mod to try to upgrade Kobo's built-in reader so it's more correct, i.e. more faithful to how KOReader renders text. Sharing it here since it may be interesting for anyone with Kobo e-readers: https://github.com/nicoverbruggen/NickelTypeFix
I use it because it supports opds and old Android versions (I have an old Android eBook reader).
I host my books on calibre web and never need to do anything beside opening the opds section on koreader and picking what to read.
I love KOReader on Android, but unfortunately it requires granting permission to manage all files on the device. I would prefer if it used the approach most apps use, which is to select a folder on the device that it can access. Then I can move all my books into that directory and KOReader would not have access to all of the data on my phone.
KOReader is awesome and it's my go to for most e-reader reading. I've recently been trying out Plato (https://github.com/baskerville/plato) as well and it has a really nice experience for reading PDFs. It crops the margins and pages through the PDF in chunks nicely.
If you have a newer Kindle and some hacking skills, consider looking for new Kindle jailbreak methods. The existing jailbreak methods don't work on newer firmwares. ( See https://kindlemodding.org/kindle-models.html )
I have a kobo ebook with [plato](https://github.com/baskerville/plato), it includes koreader but I found the built in mupdf much more intuitive and elegant.
The thing I find the most valuable on KOReader is something I haven't seen mentioned yet: the book map[0]
It shows you chapter and section divisions in a single screen, along with black bars to show you which pages and chapters you've spent a lot of time on. I use this very often to jump back to pages or chapters, or look at which parts confused me. It also visualizes where bookmarks and notes are. When you want to see a segment in more detail, you click there and it brings you to a 6-page zoomed-in view.
Let alone being more useful than the Kindle or Kobo UX, it's more useful than the book UX.
So good. I've built a plugin for it to allow me download books from my Jellyfin server on my Kindle 3 Keyboard (from 2010!). Was lovely for develop for and the wide compatibility of KOReader has made it a great investment.
Did anyone made a comparison across different devices for running this? I am curious on what is the best device today to run it, and also the best when accounting for cost of the device too.
I love KOReader! I use it on my Kobo Clara Colour with Calibre. Love Wikipedia lookup, customization options, and the fact that wifi is off by default.
If you like the statistics you might enjoy BookOrbit. I'm a sucker for stats like this and love having them centralized so that it's not just on my e-reader (in case it dies or if I read on another compatible app that syncs progress/stats).
My wish is to see ebooks become first class citizens on all digital devices. Apple has a native ebook reader built in to their devices. It's cumbersome and bloated, but it's there. No web browser except Yandex has built in ebook support, even though it would be the easiest thing in the world. Android, Linux and Windows have no built-in ebook reader, as far as I know.
Murasaki [1] is the most performant and sleek ebook reader you can get for MacOS currently. It's magnificent, but the creator has regionally limited who can get it, unfortunately.
The old Microsoft Edge had epub support, and even a nascent ebook shop and a nifty note-taking/annotation mechanism (there was even a restitution payment made for folks who had taken notes), but Microsoft gave up on it when they shifted to a rebadged Chrome.
I really appreciate you mentioning Murasaki - thank you. I've been looking for something like this for a long time, because every single EPUB "reader" out there does so much more than just read EPUBs. This one does just that, I love it.
To be fair, desktop linux doesn't really have built-in anything (except what's appropriate for a kernel, like filesystems and a TCP stack...). Many linux distributions package epub readers (calibre, okular, fbreader, bookworm), and they tend to be really easy to install.
It doesn’t seem like it’s a huge ask imo, and I’m also pretty surprised that they have such limited support, a mostly text format like epub really should be simple to add functionality for.
Less surprising but still annoying is how many hoops you need to jump through to get a good reading experience for manga, particularly on macOS. I had to try many options that were either too buggy, too difficult to install correctly, various aggressive paywalls, or straight up don’t function with high quality scans.
Eventually I landed on one(will edit the name in when I have access to my laptop) that functions well but has some memory issues in importing books, possibly a memory leak.
Maybe I’ve just become shit at finding apps in the modern unsearchable age, but it really feels like reading of all types has diminished enough that we are an unserviceable market.
I use KOReader on everything except e-ink devices.
Linux desktop. MacOS laptop. Android tablets. Android phones.
Where-ever I am, I can pick up a device and continue reading from where I left off. I have the same config everywhere (it would be nice to be able to distribute that) for gestures and taps. I use the same font everywhere (TeX Gyre Pagella, which is a Palatino clone.)
I always have a phone, a laptop, a tablet or a desktop to hand. The tablet is a great device for reading comics as well as books. The phone is a terrible device for reasing comics, but fine for books.
I run this on a pinenote, and I love it. Only sad thing is that I started transitioning to Linux and then lost interest, so I've only got about 8GB for data on the Android partition. I use syncthing to sync a folder with my laptop, so I just push a pdf into the folder on the laptop and then it turns up on the pinenote in koreader.
I have KOReader on Kindle. But its UI is very odd. Recently found plugins and patches. After installing a few something was causing weird errors. Gave Claude KOReader log and it found comic reader plugin to be the problem.
Then I installed a fast reader plugin, claude fixed its flashing and added more features. Being able to SSH via KOReader and letting an LLM fix or improve things is so awesome and freeing.
I really like that this exists, but I found the menus and UI to be rather non-intuitive. My main use case was to sync reading progress between my Kobo and my iPhone. I was able to do this using KOReader on the Kobo & the Readest app[1] on iPhone (also open source).
Ultimately I decided to get rid of KOReader because it felt a bit laggy. The gestures (eg: swiping up on the left side to increase frontlight brightness) didn't work well either.
I eneded up writing my own software to sync progress from Kobo to a KOReader Sync server[2] which my Readest app also connects to (love that unlike the Kindle, the Kobo is quite an open system). You can even set it up so you can SSH into it[3].
[1] https://github.com/readest/readest [2] https://github.com/koreader/koreader-sync-server [3] https://www.mobileread.com/forums/showthread.php?t=254214
I really appreciate that KOReader is an option. On my older Kindle (first-gen Paperwhite), the default reading experience had declined until page turns take several seconds. Firmware update and factory reset wouldn't fix it. Using the default reader just wasn't a viable scenario.
I jailbroke it, launched KOReader, and it's like I have a new e-reader. The amount of customizability gets kind of in the way, but once it's set up I don't really think about it from one month to the next. I also didn't feel the need to upgrade my original install either.
Amazon bricked the first gen paperwhite, so I went on a similar journey. I started out making a single rust app on it, then went down the rabbit hole of trying to replace the shell/launcher. https://github.com/justinledwards/ferrink-home-assistant and "ferrink" is the launcher. It is pretty snappy on the paperwhite for what it is.
I tried to set up KOReader multiple times and always got stuck figuring out where all the settings are and how exactly they work. It seems very complete, but I'm just too dumb to actually use it.
I went through the same on my 10-inch Android tablet. The key is just sticking with it long enough to get it set up for your needs and prefs. I'm glad I did because it's really great. While the docs are quite good, if you get stuck just use an LLM. Once you get it configged, you won't be using the UI much.
KOR is both complete and very capable. It can very probably do everything you'll ever want but, as many people observe, the UI is just a bit weird. That's not to say the UI is broken or inconsistent, its simply that its approach is a little different than you'd expect. Once I got familiar with the main flow of the UI, it hasn't been an issue for my daily-use needs. If you care about flexibility, control, features and having it "your way", I think it's well worth the one-time effort to set up. It's also extremely user-moddable with Lua scripts. I use several found here: https://github.com/sebdelsol/KOReader.patches.
I also found all existing e-reader software to be lacking, and all I really wanted was a basic reader. I ended up writing my own with Rust and MyPDF (the latter doing all the heavy loading).
The hardware is great, but the software is pretty lacking. Apparently a lot of the tools out there are from folks in similar situation: had the hardware, but the software to drive it was lacking.
It's good to have options.
Most software has compromises.
KOReader seems to have functionality in one place in one reader app that other e-reader apps don't.
https://github.com/baskerville/plato might interest you. I've yet to try it, personally.
I installed it on my Amazon Kindle and I couldn't be happier. It shows once again that free software is superior to proprietary software. Free software grows slowly to make users happier and not to attract them with useless features to extract more value from them. Congratulations for this great piece of software.
I’m a heavy KOReader user and absolutely adore it, but I think it definitely trades user-friendliness for power and flexibility. The Kindle proprietary store has a far more user friendly UI imo, though it’s getting progressively worse (and the fact that kindles now default to showing you the store pisses me off to no end). KOReader plugins really close the gap though.
> I think it definitely trades user-friendliness for power and flexibility
A tale as old as time with OSS software from what I've seen. So far the only exception that I've seen of a FOSS piece of software with great UX is Blender[1]. With UX not being a first-class citizen on Linux, exposure to a solid universal tooling to create great UX also exacerbates things.
I think the issue of bad UX and OSS are comorbid because good UX needs an extremely opinionated mind at the helm and a culture of prioritizing features and saying "No, this is not important" which OSS generally lacks.
[1]: https://www.blender.org/
I don’t know about that.
I think Libreoffice is easier to navigate than ribbon-era Office.
I think especially Gnome, but also Kde has better settings than Windows, which is spread across a new and a classical view (or more?).
I also think MacOS finder is worse than Windows/KDE/Gnome equivalents. When you strip so much away that people have to remember strange key combinations to jump/navigate to specific directories you have really gone too far.
And mobile UX (android and iphone) seem to me worse than any desktop system. Nothing is consistent (sharing data between apps), nothing ever seems settled (settings move around in the central settings apps every few releases).
We could argue in depth. Let me head it off a bit - taste is absolutely a thing, but consistency across releases is evidently a good thing unless you are constantly in a situation where your existing userbase is dwarfed by the prospective one. There’s a reason we hang on to diskette icons, don’t change from desktop to metro to ios style desktops every release and so on.
Last point: OSS software can be misguided, but it never seeks to bamboozle the user to make some corporate goal succeed. It won’t nefariously stuff files on a cloud or actively make it hard to export data or be incentivized to NOT interoperate with devices or programs shipped by competitors.
People say that and I used to agree, but honestly I use neither MS Office nor LibreOffice heavily anymore. Nowadays I can figure out what to do in MS Office very quickly but LibreOffice's menus are a confusing maze (even when switched into the more ribbon-like mode).
> So far the only exception that I've seen of a FOSS piece of software with great UX is Blender.
Most OSS software favors power users instead of total beginners. And even Blender is not a great exercise in discoverability. You need training to use it.
The stock software in Kobo and kindle can be used within minutes because they don't have a lot of features/options. And it's totally fine if that's what you need. Just like Windows 7's Notepad. But if you need more capabilities, your wish is notepad++/vim level (which does require more learning), which is what koreader is.
> Most OSS software favors power users instead of total beginners. And even Blender is not a great exercise in discoverability. You need training to use it.
I think it’s more subtle than that. I am a power user — I was compiling my Linux kernel in the 90s, I wrote my own SSH tunnel manager 20 years ago, I always fiddle with settings, etc. etc.
However, I am constantly frustrated with a lot of OSS software because it expects you to think like the developer of the tool, instead of having empathy for the user. What feels obvious to the developer of the tool (I am making up a hopefully-representative hypothetical here, but finding the change of font under “Theme” because it’s how “it looks” but finding the font size under “View” because, well, you view it) feels frustrating and nonsensical to a normal human who relates both the font and its size the same way in their mind. Again, generally — I’m making generalizations here and not calling out any specific software, but trying to illustrate the feeling that I get.
When I switched to the Mac in 2002, it is because these sorts of things made sense. Yes, there were and are frustrations because of this sort of opinionated design mentality, but I judged the benefits to outweigh the positives. Unfortunately, Apple squandered this culture and skill and nowadays I often find the platform as frustrating as OSS ones, to the point where I have switched back to 50/50 time split between platforms.
I find this is mostly just a "mindset" difference.
OSS software aligns mentally with "tool". It only exists because someone had a problem to solve, and they wanted a tool to solve it. Generally, people should expect to have to learn how to use tools. Then they solve their problem and move on. It takes effort, and the result is mastery which gives you new capabilities.
Consumer software (and especially anything ad supported or social media adjacent, and sadly in many respects, lots of modern SaaS companies) want to be as glitzy and smooth as possible, but they don't actually want you to solve your problem. Instead they'd really prefer that you simply spend as much time looking at their software as possible. So the experience can be quite pleasant, it feels nice, things feel obvious, you get the dopamine hits quick and fast. But after a while you realize you aren't actually all that productive (or even productive at all) when engaging with them. Because the goal of this software isn't to help you solve your problem. The goal is to keep your attention and extract your money. If it happens to solve your problem... sometimes that's fine, sometimes that's actually counter to the primary mission of extracting your time and money.
> The stock software in Kobo and kindle can be used within minutes because they don't have a lot of features/options.
Afaik koreader itself does not support stylus while the default reader in kobo does (somebody made a plugin lately but not sure how stable it is). Not to say that koreader is not amazing, but it does not mean that FOSS always has strictly more features. If koreader had strictly more features and I wanted some of them I would choose that. But I also right now want to use the ereader to read books and take notes, not tweak plugins and configurations. I have been in this "power user" loop where I spend more time with configuring rather than doing the thing, and I am a bit more selective with when this makes sense to me.
I love the discoverability of blender in the sense that I can hit space and start typing the name of the thing I want to do and run it from there while it shows me in what menu I could find it and what shortcut to use. And next space it remembers the last thing I ran so to repeat it its even faster.
This requires however to remember the name of the command (or parts of it). I often remember that but not where to find it or the shortcut.
It also requires that you chose the spacebar search option, which is the only correct option if you ask me. (Not a pro. Just messing around with blender sometimes.)
you will spend much MUCH more time as a power law user than as a new user, such that almost any % gain in productivity once familiar is worth almost any months of unproductivity when new.
> I think the issue of bad UX and OSS are comorbid because
I think UX is simply harder when you're not leading the user by the nose to your most profitable features, and removing or obscuring the others. Commercial UX is more akin to advertising than UX, so there's no wonder that it makes very clear the few affordances that it offers (and bizarre when it doesn't, like the "flat" period.)
The other problem with FOSS UX is that millions of dollars haven't been put into it (literally: 5 developers = 1 million dollars/year.) The wonderful benefit of FOSS UX is that you have plenty of time to learn it, because every feature is already there, no one is forcing you to upgrade, and no one is moving things around and deleting things because it is more profitable to them.
Commercial UX had better be good enough to learn basic functionality quickly, because it's going to be completely recycled every year. It also doesn't want you to learn anything too deeply, because then you might become a (gasp) "power user" and make unprofitable demands.
Imagine using the same type of software (e.g. an mp3 player) for a couple dozen years and thinking that it's a hassle to figure out how to learn it. Imagine being boiled like a frog to relearn how your mp3 player works every couple years for a couple dozen years, and dreaming you've saved some sort of time or effort. Imagine you've used mp3 players for a couple dozen years, you still don't know what an mp3 is, you don't know what a file is, and you don't know how to get your mp3s back after switching your mp3 player without rebuying them. Eventually you switch to streaming, give up making any decisions, and take whatever the marketers prefer.
This is "good" UX.
I jailbroke my Kindle and moved to KOReader last year, primarily to get away from the Amazon jail. Just the bare KOReader UX was pretty utilitarian. It lacked polish for sure. I'll have to agree that, as noted elsewhere, the KOReader menus can be difficult to get a grip on.
If you're working at just the most basic level of functionality, I don't think KOReader is necessarily worse than native Kindle. The latter is hampered by being very opinionated about how you should experience it, and that includes pushing their store above the user's own library, and this is a real annoyance.
As you start to demand more capabilities they diverge more. Organizing when you've got many books on the device is clunky on both platforms, but in different ways. The native Kindle options for grouping are simple, but not necessarily easy. They're very generic, and very cumbersome to work with. Bare KOReader's support for folders makes more sense to me, and it's easier to deal with bulk books than is Kindle's.
Getting books onto Kindle is super-easy if you get them from Amazon, but complexity ramps up for other sources. Your best bet is plugging it into USB and transferring via the file system. Native KOReader add to this an OPDS capability (if your book repository supports it), which works but is less than pleasant. If you use BookOrbit as your repository, there's a plugin that gives you the remote BookOrbit UI from the Kindle, which makes things a LOT better.
I experimented with Simply UI for a bit but could never get it to work quite right. About a month ago I found Bookshelf, and this makes the UX pretty wonderful. It has a very attractive and intuitive UI. And it simplifies the interactions needed for group management a bit.
Bottom line is that KOReader + Bookshelf are, for at least a power user, a potentially far superior experience compared to baseline Kindle.
I've tried hard to make Bookshelf work for me, but I find the UI confusing, going off in unexpected directions, and it's very unintuitive. I've got SimpleUI at the moment and it's comfortable, even though the library interface is lacking.
I don't know what the situation is like for Kindle, but there are atleast two open source alternatives for Kobo. KOReader is the Swiss Army knife, Plato is easier to use.
A few people are suggesting that KOReader is symptomatic if the issues with open source software. The reality is it targets a particular group of users.
I think the only proprietary software companies with any shot at longevity are Japanese companies. First Japan leads by far the ranking of oldest companies in the world (https://en.wikipedia.org/wiki/List_of_oldest_companies). Then we have actual software like Zelda Breath of the Wild which is a technical marvel comparable to the original Rollercoaster Tycoon considering how well it runs on the severely limited architecture of the Switch.
I think this boils down to profit not being the only driving force for these companies, but prestige and a sense of duty and responsibility towards something larger and less immediate.
I think you know nothing about Japanese software.
You're assuming long lasting soy sauce companies have anything to do with software development. Japan produces great video games despite how terrible otherwise the developer environment and culture is there and nearly all of the other software shows it.
Didn't say they are good quality, or the working environment is nice or anything, just that they have higher chances or living a long time. The reasons might not be any more or less commendable, but they are different than chasing the highest profit margin possible in the next quarter
Japanese software and software technology culture is amongst the worst in the world. They're famous for failing to adopt modern ways of working, tools and as an industry is seriously struggling. There's fantastic video in this from Asianometry: https://youtu.be/ky1nGQhHTso
This podcast about the history of zaibatsu, hardware, and software comes to mind. https://www.disruptingjapan.com/the-forgotten-mistake-that-k...
> Software was not viewed so much as a product, but more like a service, similar to integration, training, and ongoing support and maintenance. It was usually sold on a time-and-materials basis, and sometimes it was just thrown in for free to sweeten the deal. The real money was in the hardware.
> Software development was considered rather low-skill work. It didn’t pay well and was viewed as a kind of clerical work. The job was simply to write software that was close enough to whatever sales had promised the client while they were out drinking last week.
This sounds like the way software was viewed through at least the 1960s in the US.
Until the threat of anti-trust against IBM, and the latter's decision to “unbundle” its software from its hardware, in 1969. There had been proprietary software before that, but very little horizontal software (OSs, development tools, etc.) Autoflow's flowchart generator was a rare example of this.
There is nothing inherently special about Japan or Japanese people. You can pull similar examples from many other countries.
I take it you've never been to Japan...
Wouldn't wanna live there permanently. Wouldn't want to have been born Japanese. But my god the products and services are head and shoulders above my baseline expectations; it's simply nicer.
I have lived in Japan.
> Wouldn't wanna live there permanently. Wouldn't want to have been born Japanese.
So I take it you understand that there is no free lunch.
The apps I need to use for Rakuten Mobile are certainly... special.
get a point card and try to register it online to pay your water bill and then tell me this
I agree. I didn't say it's special, only different. Can you say adult adoption is something common in the US?
https://en.wikipedia.org/wiki/Japanese_adult_adoption
I have always found the adoption loophole to maintaining a family business hilariously smart.
I also understand why it’s not something common outside of Japan. Selling your family name in exchange for (maybe) keeping your business alive is distasteful at best.
It's weird and shows how heinous the working culture is, salarymen are almost property of the company they work for
I thought I was reading a summary about the Yakuza.
Bro has never played the thousands of shitty visual novels. Hell even from software games, which are beautifully well designed, are technically embarrassing
They are, but the central theme of the convo here isn't quality but longevity
this is complete nonsense. 『ローラーコースタータイクーン』はそもそも日本のゲームではありませんだよね笑
> Breath of the Wild which is a technical marvel comparable to the original Rollercoaster Tycoon considering how well it runs on the severely limited architecture of the Switch.
What? It can’t even maintain a stable 30fps on its own target hardware. That’s not an example is point to for something running “well.”
Yeah, it's genuinely my favorite game of all time but to compare it to Rollercoaster Tycoon as "a technical marvel" is doing a massive disservice to Chris Sawyer.
Software
Software Japan
I've been a Kindle user since way back in 2010 with a Kindle 3G. I had a pretty huge amount of money invested into a library of books on Kindle. I installed koreader on my paperwhite earlier this year and haven't looked back. Even if it weren't for the limitations put on the walled garden for books in the kindle ecosystem, just the software upgrade alone feels great. When you hit buttons in koreader it actually responds in less than a second. I hadn't even realized how frustrating the UX of the kindle OS was until I realized the hardware was capable of feeling snappy.
There's obviously a lot you need to provide yourself that Amazon gives "for free" with the Kindle ecosystem, but using koreader with OPDS and kosync for synchronizing progress across devices, I'm very happy to be just buying DRM-free books elsewhere and hosting a small OPDS+kosync server on my home server. Installing tailscale on my kindle makes it so I can even fetch books/sync progress when I'm away from home without needing to expose my book server to the internet.
What extra features has over regular kindle software? I find kindle features enough but I want to know if I’m missing something
As someone who thought the same (stock was enough for me) until I had some free time and switched, here are some things I'm really enjoying, in no particular order:
- Format support: EPUB, CBR/CBZ (comics, graphic novels), PDF
- Dark mode
- Fully programmable gestures and shortcuts
- Automatically syncs with my readeck instance (think readitlater/instapaper) to dowload the articles I save for example here on HN
- Calibre integration over wifi
- RSS/Atom
- Custom dictionaries
If you are into manga, there is an extension for directly downloading them on the device
I'm really happy I made the switch.
What's the point of Dark mode on an eink screen?
For some people it's less eye straining if they're reading at night, doesn't help for me personally, but it's a popular feature
Because most of the page is dark, with light only coming from the text, the total light emitted is much less. That makes it less annoying to my wife, when I'm reading before going to sleep.
Eink doesn't emit light.
this is the worst kind of pedantic engineer comment that seems to infest this site. they're obviously talking about the frontlight. dark mode reflects much much less light back at the user through the lightguide because the dark bg absorbs more of the light.
Many Kindles have backlights for night-time reading!
If you want pedantic ridiculousness, well, notice that I never said that the e-ink emits light. It does, however reflect light back from the device's frontlight. The device taken as a system most certainly emits light, but less so when in dark mode.
I have no idea but users seem to like it despite all the ghosting.
The reason I use koreader is because it can sync my progress on disparate devices. I have a normal sized kobo and also a phone sized viwoods eink device.
Being able to put epubs bought elsewhere and reading them without needing to convert the files is a huge plus
Where do you buy your epubs from?
In my case from different places like itch.io , smashwords.com, gumroad.com, some fundraisings that provide epubs. You also have some nice free places like standardebooks.org. Or you can sail the digital seven seas if there's no availability.
Theres a long trail of smaller stores, including Kobo store and ebooks.com
Standard Ebooks for high quality public domain books, though they also offer azw.
https://www.gutenberg.org/ has more books than you will be able to read in your lifetime for no cost. Some are classics for a reason, some are garbage - same as any other publisher.
There are a number of other free ebook sites out there as well.
I wouldn't assume that purchases are taking place.
Considering that the GP said
> Being able to put epubs bought elsewhere
I'd say it is in this case.
Kindle already supports that, or at least my 5 years old vanilla Kindle can.
really, epub without conversion? Which kindle can do thay?
Stuff which may be above the kindle stock features (as seen on Paperwhite 10):
- Allowing to highlight text across pages. Used to work in the past but no longer works
- Allowing exit to library from mobi files without a cold reboot of the device. Used to work, no longer works.
- Not deleting contents of my library on an update overnight? (files still on disk, metadata gone, no longer visible on Kindle)
- consistently working dictionary, offline, at least for English texts? (used to mostly work, with recent updates it is broken)
- Not getting worse on every update
- Better keyboard layout, maybe supporting smaller languages
- Not deleting purchased books remotely
- better bookmarks and navigation support. I find Kindle useless for the technical reading and learning materials, as navigation and cross-referencing is slow clunky and useless, I need paper books for that, or a computer.
- Better image display? Also hinders proper use for digesting technical content.
- Text Search?
- EPUB support.
- Better and faster UI. I always thought the Kindle was just slow, nope, it's just really bad software
- Customise any/everything. Font size, line spacing, paragraph spacing, margins, header/footer content, the list goes on
- Ability to use things like BookOrbit (or alternatives) to manage your books and sync your progress/stats.
- LLM-integration through plugins like KOAssistant, highlight a word/phrase/passage to get it explained to you. This was invaluable for me when reading through a series from the 1950's about the late 1700's, lots of phrases I'd never heard. Many I could grasp the meaning from context but it was way more fun to hear the "why" behind the phrase. Same with historical events that I am less knowledgeable about than I wish. Let's me stay "in the book" instead of picking up my phone.
- Full control, some people don't care/need this but I love being able to SSH into my Kindle and do whatever I want. I love having my entire book reading experience end-to-end be fully open source and self-hosted.
Ability to use things like BookOrbit (or alternatives) to manage your books and sync your progress/stats
I discovered BookOrbit about two months ago. I think that it, together with the KOReader plugin that exposes the remote BO UI, may turn out to be a game changer in how I organize and access my ebook repository.
Same here, I jailbroke my kindle just 1-2 months ago (when the PW5 JB came out) and I had been using BookOrbit for only a few weeks before then. Since then I've read over 15 books and been loving BookOrbit and KOReader.
Thanks for the BookOrbit hint. Seems very interesting.
I see it supports audiobooks and ebooks. Do you know if there is any way for keeping sync between an audiobook and ebook?
It does not have any sort of "whispersync" but, ironically?, I feel like whispersync could be recreated with things like Whisper and parsing the epub/whatever to line up progress. BookOrbit is in active development from what I can see (I'm not connected to the project, just a happy user) and it wouldn't surprise me if that was a feature in the future. It's something I've mulled over building for a while (even before Whisper).
For my Audiobooks I don't use BookOrbit because my setup is:
- Buy on Audible
- Rip DRM off
- Add to Plex
- Use Prologue (iOS only) to listen
And I freaking love that setup so I'm not looking to replace it currently.
How do you rip the drm off audible? Id love to free my audioooks.
IMO the most important one is more options for PDF rendering, often allowing you to read PDFs without squinting.
Well tbh the reason I like it has to do more with calibre (free software)
Never updating if you don't want an update. I see no reason for my e-reader to have updates. I have a Kobo and after I updated it once about 5 years ago I haven't since because it already does everything I need it to.
Not only is it the superior piece of software, the freedom it offers by dissociating the choice of hardware from the choice of software is another example why free software and interoperability is something we should strive for.
Funnily koreader comes with a lot of features that are useless to me, but I love that I can just disable the respective plugins.
I like the Readwise integration via plugin and the EPUB support, but for the first few days with it, I was busy understanding the menu hierarchy and trying to figure out how to match the styling and spacing of my native Kindle books. The out-of-the-box experience is unfortunately just "tasteless," and I needed some time to warm up to it.
Yeah and like the majority of open source software, the UI is garbage and unintuitive.
It shows reading stats that I absolutely love!!
I'm immensely thankful for koreader - it improves the reading experience so fundamentally that it literally drives my purchasing decisions. I got a remarkable 2 precisely because it was known to run it well. When I got a new kindle, I went for a refurbished one hoping it'd be one FW version behind (it was! lucky me) so I could jailbreak it immediately, and run koreader.
Which reminds me:
- I'm still a primitive user. Sync reading state, reflow, calibre link, yes, but I'm at maybe 10% of the features, might even be an overestimate. I may finally have to cave in and go through its manual
- I literally endure calibre because that's how I feed koreader. Any alternatives?
- Is there really no practical way to mark a book as read other than give it a star rating or a custom tag?
- Does anyone know of anything coming close to this experience on an iPad?
- I've never given them a cent or contributed a line of code or even filed a bug report. That changes now.
> - I literally endure calibre because that's how I feed koreader. Any alternatives?
I use USB mass storage.
In details, I configured KOReader not to start mass storage automatically, so I need two taps after connecting the USB. Then on my Linux PC, I mount the device, exec a `rsync` command, then umount.
My ebooks directory uses Git (with LFS) so I can update it from several computers. I considered switching to git-annex, instead of gitlfs+rsync, but I'm not motivated enough to change a system that works.
> - Is there really no practical way to mark a book as read other than give it a star rating or a custom tag?
There are 3 states : reading, on hold, finished. The rating is optional. A long press on a book title will give access to this states and more.
All that metadata is stored in lua data files (a bit similar to JSON). With mass storage, it's easy to read or update these files. I use "on hold" to mean "dropped" (and I hide them in the listings).
I've been messing around with this as well, and there are a few good options now, if you're willing to self-host services:
- calibre-web, as a pure web front end to the calibre db
- Calibre Web Automated, which is a rewrite of the app, with a better web UI, that is faster and adds functionality
- Grimmory, a Java-based book mgmt. app w/ a web front end too
- BookOrbit, similar to Grimmory but written in Node and seems to scale better w/ 100k+ book libraries
The better way to get books onto KOReader is via connecting to these apps' OPDS feeds. Wireless, and most of these other apps have better library organization.
Heads-up for BookOrbit users:
Last week they released a change that put the header Strict-Transport-Security into all responses (yes, even non-HTTPS ones!). This broke not just BookOrbit, but every other app I had running on that server, because suddenly everything being served by that host refused to work without HTTPS.
I probably should have done it sooner, but I spent a big chunk of the afternoon setting up new DNS entries so I can access each app through a different hostname. That was easy enough for me, running OPNsense with my own internal DNS, but you may not have that much flexibility in your home.
I submitted an issue (see https://github.com/bookorbit/bookorbit/issues/760) and a few days later, they created a semi-fix such that the header is only sent out in secure responses. But this still has the effect of forcing every app on that server to require HTTPS.
> “ I literally endure calibre because that's how I feed koreader. Any alternatives?”
- Syncthing plugin for Koreader (for syncing your ebooks with a computer / phone / tablet)
- RSS feeds for newsfeeds
I use BookFusion. A plugin for Calibre (which is still my central library) lets me upload chosen books to the BookFusion server, after which I download to KOReader. Using the BookFusion plugin for KOReader I can sync reading progress and annotations to back to the cloud, and read on iOS or other devices using KOReader.
> - I literally endure calibre because that's how I feed koreader. Any alternatives?
On first exposure to calibre I was put off by its weird UI and how opinionated it was about filename conventions. But I learned to accept that it's the best solution out there with the most community support, and it grew on me. There are also a few third party projects that can interact with its database.
Someone claims to have ported it to iOS but I haven't tried it and one of the open issues says that the release build doesn't work:
https://github.com/hezi/koreader-ios
Awesome, even if it doesn't currently work, good starting point. Thanks.
You can use the regular Kindle viewer once you jailbroke your kindle, but KOReader has native epub and pdf support so you don't have to use a converter when uploading your books.
I did find it hard to get the bezels to be even and it still doesn't always format well depending on the book. I still kind of prefer the default viewer.
I use this plugin in KOReader which lets you download books from Z-Library within KOReader.
https://github.com/ZlibraryKO/zlibrary.koplugin
Another cool thing is you can use custom fonts and dictionaries. I use the OED short version and the Wikipedia one. There's built in ones that it can download but pirated ones like OED you have to upload yourself.
Unfortunately on MacOS it seems you have to use Amazon's app to access the filesystem.
Edit:
They changed it on the newer Kindle which I have.
There's open source alternatives to the send to kindle app.
Where do you download the OED dictionary? I've never found a source for it, and assumed it was not available publicly.

KOReader comes with SSH, so you can just SSH into it.
Another cool thing is you can use custom fonts and dictionaries.
To be fair, it is now possible to load your favorite fonts onto baseline Kindle.
> Unfortunately on MacOS it seems you have to use Amazon's app to access the filesystem.
Hmmm not really my experience, unless it's a new thing. I am still able to access it via finder. Although I need to exit KoReader first and go back to the stock UI.
>Unfortunately on MacOS it seems you have to use Amazon's app to access the filesystem.
I can recommend using a Filebrowser plugin for KOReader, that way you can access the file system over a web interface and upload that way. No cables needed or anything, quite convenient.
The latest generation paperwhite (“PW6”) and color readers use MTP rather than acting as mass storage devices.
I use OpenMTP rather than Amazon’s software, and that works fine for me.
same experience here, jailbroken Kindle, installed KOReader, tried it and returned back to default viewer, don't exactly remember the reason, maybe overcomplicated? (especially since it's device for my kids, it doesnt have internet access, I just put there books offline)
It's a shame the out of the box UI/UX is so bad, it really feels like the GIMP of e-reader software at times.
I think the Zen UI plugin is mandatory to have a good time with it.
https://anthonygress.github.io/zen_ui.koplugin
That's very helpful, thanks! The KOreader UI is... Rough.
Love all the options, especially the ability to use folders on the device storage as the primary way to organize my books, but trying to figure out where a setting is and change it has been frustrating from the first day I installed it.
Will give the Zen UI plugin a go. Does it still support the on-device folders as the main way to navigate through your books?
KOReader is my jam! With its reflow for PDFs, I've used it on my Kindle Oasis 2 to read everything for my undergrad and graduate degree. Some years ago now, I wrote a script that converts the annotations to Obsidian [0], and then another little script to automatically keep my "Articles" folders in sync between the Kindle and my laptop.
Very grateful for this software!

Interesting. I generally hate proprietary software, but I've actually been really satisfied with the kindle UI. I don't use the store at all, simply email epubs to it directly. (I usually only move 1-5 books max at a given time, so this process feels really simple to me). The only adjustments I need are the text size and front light, battery life is amazing. I'm guessing this would be really useful if I had advanced needs, but for just reading epubs, kindle is a really good UI.
You must have a newer kindle. Koreader was basically my best bet once mine (2012 vintage) stopped being supported by Amazon. Native epub support plus other goodies. I’m sure you’re aware that emailing an epub to your kindle converts it to mobi before sending, potentially mucking up the formatting.
I think mine is from 2019. I didn't realise it wasn't natively displaying an epub. I haven't noticed any breaks, or maybe I attributed any errors simply to the original epub and didn't realise it was a conversion error. But also the things I read are quite plain and text heavy so perhaps that's why.
Lots of nice features but the UX and UI are so painful that it's not worth jumping from the stock kobo reader for me.
It's nice to have another option though and if the UX improves one day maybe I'll use it as my main reader.
I don't like the UX but the extra controls on ebook rendering was worth the pain for me, since almost all of my time is just reading the ebook anyways.
I got to the same conclusion. Installation was also painful; understandable, these platforms are clumsy.
The software itself is magic, kudos to all the developers and community.
Came to the same conclusion too – I appreciate that it exists, but the UI felt really complicated and disorganized.
Being able to read magazines was a big upgrade for me v the native kobo reader
koreader is wildly unintuitive (just try to look at battery statistics, and marvel that it's in a submenu of a submenu with only 2 items) -- but it is very powerful. once I got used to it's quirks I can't go back. Things i use all the time on my phone-sized ereader :
1. calibre sync built in 2. customised estimated time remaining/progress bar 3. custom fonts and margin support 4. hardcover.app sync
I absolutely love KOReader on my Boox Go 10.3!
It has super useful features like the semi-auto-cropping which removes margins in PDFs (like papers or books), including unnecessary things like page numbers or similar, so that you can really maximize the size of the core content. It also has a nice chapter overview and other useful things!
Truly one of the best pieces of software I have used so far.
My only real complaint with KOReader is that the book browsing UI is file and folder based by default, while virtually all other ebook readers support some kind of cover based library view you can sort 20 different ways based on metadata rather than filenames etc.
It's not a huge issue, but I find just browsing my collection to find a read a lot more enjoyable on other ebook readers. IIRC there are plugins to add this feature, but it's not present out of the box.
On the few Kobos and jailbroken Kindles I've used it on, it also drains the battery significantly faster than the stock reader app, although not enough that I couldn't last at least a few days. On stock software I can go weeks between charges.
My experience with battery life seems to be the opposite of yours. I'm using it on a Kobo Clara BW and my battery just lasts and lasts, even with an hour or more a day of reading. I don't have any firm data on it, but I know that right now I'm at 52% battery and it's been at least a week and a half since I plugged it in anywhere.
I use KOReader a lot. After your comment, I realized file browser annoys me too. After some searching, I found an alternative view. Turns out, you can open the File browser tab, swipe down and switch "Display mode" to "Mosaic with cover images". Also seems like it's default for new versions now. This mosaic view still uses directories but it lists books as rectangles (covers) instead of lines (covers + titles), it seems more pleasant.
By the way, in the same settings I finally found how to set up KOReader to launch with a previously opened book. What a relief!
I am using koreader on my ereader and KOreader has a native support for https://wallabag.org/. They are both fantastic opensource projects, whenever I like to read a blog post I am sending them to my wallabag and therefore I can easily have them on my ereader too.
Also the fact that you can install different plugin on KOreader and customize it in a way you like is fantastic. for example just check:
- https://github.com/doctorhetfield-cmd/simpleui.koplugin - https://github.com/AndyHazz/bookshelf.koplugin
Or with Lua you can develop your own plugin for that. to people who wanted to jailbreak their Kindle I can recommend these two links:
- https://kindlemodding.org/ - https://www.youtube.com/watch?v=Qtk7ERwlIAk
All in all I am supper happy with KOreader and can't imagine to use anything else
I was considering installing KOReader on my Kobo. However, I have decided that I don't want to do any tinkering with my Kobo. The entire point of my Kobo is kinda to be a distraction-free device, and messing around with installing stuff on it would ensure I would get distracted messing with the software when I should be reading or sleeping. It means I don't get to sync my progress with my phone, but I'm ok with that.
It's so funny that you say this because I 100% agree. I have a Remarkable tablet (several of them in fact) and the people on /r/remarkabletablet are always looking for ways to complicate their Remarkables with KOReader or any other number of hacks.
I want to write notes on my Remarkable and I want to read on my Kindle. They are both excellent at that right out of the box.
I'm beginning to suspect that many people actually like being distracted more than they like being distraction free!
I have this on my Amazon Kindle and I freaking LOVE it!
Paired with BookOrbit [0] and using plugins like BookShelf, BookEnds, and KOAssistant I have the best reading setup ever.
The speed of this on my Kindle is _insane_ compared to the stock software. I'm not talking about page turning, that was fine on both, but navigating menus is way faster.
It was a little finicky to configure but once I got a feel for it I didn't have a problem and 15 books read later since I installed it a few months ago and I never touch the settings.
My favorite plugins:
BookShelf: Best UI for viewing my books by author/series/etc IMHO. Much better than the Kindle default UI and much snappier
BookEnds: Configure the header and footer of each page to show what info you care about most. There are community configs you can test out easily and download right on your kindle if you like them
KOAssistant: highlight some text and throw it at an LLM with a provided prompt or your custom one. This was invaluable when reading the Hornblower series which used a lot of older english words/phrasing as well as nautical terms (which I'm completely unfamiliar with). I enjoyed the books way more since I could figure it out inside my kindle instead of constantly having to pick up my phone to look up a phrase.
BookOrbit: It provides a plugin for KOReader that syncs your progress, annotations, etc.
KOReader is table stakes for any e-reader I might consider. If my Kindle died tomorrow I'd have a Kobo or similar on it's way to me within hours. I won't use any reader that doesn't support KOReader after using it for these last few months.

If you use a Kindle, you have to jailbreak it first before installing it. There's definitely been some improvements with user experience at least with apps since I first jailbroke it. There's like an appstore with games and KOReader that I use.
This is the guide I used and it's up to date.
https://kindlemodding.org/
EXTREMELY confusing UI, but when you get used to it, nothing really comes close in terms of customisability and features.
Seriously, takes ages to find specific settings for the first few times.
love this project. i used it on my pinephone daily for at least a year: it does _everything_ you'd want and does it fast.
problem for me was that they vendor like 30 different dependencies in a totally bespoke way that's largely incompatible with any modern package management: it downloads them as part of ./configure (IIRC) and with no way for the OS to provide its own. so you're either stuck using the prebuilt releases without any means to patch/improve the software, or if you do want to make improvements then it's a full-time job to keep the package in a buildable state. in the end that was too much work for me and i switched to Foliate: it's noticeably slower (webkitgtk) and lacking, but it's way simpler to develop on.
maybe they've improved the build system in the last couple years, though a quick peek shows that the nixpkgs expression is still using the binary release. if it becomes practical to build from source in the future i will 100% switch back to it.

I use KOReader daily on my Kobo and my Boox Go 10.3 (Gen II) Lumi. I use BookFusion to sync with my iPhone. They all work great. KOReader doesn't have the most intuitive menu structure, but the plugin environment is excellent and there are several UI plugins that make using the software easier.
It's also great for jailbroken Kindles.
I finally installed this on my Kobo Libra 2. The UX is clunky but overall it works great. Very fast. Don’t need KEPUBS anymore as epubs render just as fast, where as that’s not the case on the stock software.
I finally got around to installing it as I got an xteink x3 and wanted to have cross device syncing back to my Grimmory server. Works great with OPDS and KOSync.
Although I miss using the native kobo sync where I could just add a book to my virtual shelf and have it auto sync to my device. OPDS seems very rudimentary in comparison, but it works nonetheless.
What's the advantage of Grimmory over Booklore?
Booklore maintenance stopped a while ago. Grimmory maintenance continues. The original author of Booklore has seemingly moved on to a new project.
Have people moved on from Calibre?
I've been slowly spinning up self-hosted services and Calibre was on my TODO. I haven't even heard of Booklore.
I'm wondering this too. I also thought about setting up calibre as I own a ton of drm free books and while the calibre reader itself is nice (the viewer is all I mainly use), sometimes I do find myself wanting to read on my phone while at a dr appointment or whatever
I tried but the whole process is a miserable experience between the stale blog posts and the dead links…
And then the UX… great project but could use a systems guy used to jailbreaking installations and a UX designer
Edit: for kobo at least
you used https://kindlemodding.org/?
Worked fine for me.
No it was on Kobo
I set up KOReader with a jailbroken Kindle. DammitJeff has a good video introducing the topic. UI is definitely awkward, but it is awesome and pretty "hands off" when set up. It also has built-in support for OPDS so downloads from places like "Project Gutenberg" are a breeze. Also, if you are a homelabber with stuff like Calibre & Calibre Sync, it all works as you'd expect.
I love KOreader for the best in class type setting imho. If an e-reader can run KOreader is a purchasing factor to me for that reason. I read a lot so it matters to me how the text looks.
I have it on my Kobo, it's really good ! I use it with Wallabag, I can save articles on my desktop and sync it before leaving for work, really nice.
I have one of those Android e-books and it's nice to find good software.
Anyways I just wanted to read using the least possible resources so I'm just using a simple file manager and mupdf (in which KOreader is based). mupdf may be simple, but it's amazing.
Thanks for letting me know about mupdf! One of my favorite things about KOReader is its ability to handle humongous PDFs on extremely modest hardware; it's good to know what this ability is based on.
Thanks for that recommendation. It is simple and yes it is much easier to just get reading than Koreader
KOReader is one of these projects where idea is fantastic, it's impressive that it works, and the result is sufficiently quirky that I couldn't get used to it. UI is cumbersome. On kobo, it feels like it's draining battery much faster than the "regular" kobo OS. When you sync progress to KOSync with WiFi you keep getting these "Connecting to wifi" popups. And on mobile, having to use the internal keyboard feels like using the keyboard on a reader, which I do not want to.
I've never used it on Kobo (as I don't have one), but I felt that for the Kindle KOReader it was a significantly better experience than the stock experience. It's easy to sync stuff with Calibre, you can choose any TTF font, and there are more display options for reading. At least on the Kindle Paperwhite (purchased in 2015), it does not appear to significantly affect battery life.
Maybe I'm just too entrenched in the engineering space that I'm just used to "developer UI", but my wife is decidedly not a software person and she seems to like KOReader just fine.
There's a KOReader plugin that lets you sync your progress to a Storyteller server.
https://github.com/Sirozha1337/storytellersync.koplugin
https://storyteller-platform.dev/
This then allows you seamlessly switch back and forth between your e-reader and listening to the audiobook on your phone with automatic position syncing.
It's a great reader app, but as a reader of Japanese light novels it's sadly not fit for my personal purposes - last I checked vertical text is only possible in a really, _really_ hacky way (using a font that is turned sideways), and dictionary support for Japanese (or, say, Finnish with its complex lemmatization) is lacking behind browser extensions such as Yomitan, or mobile apps like Hoshi Reader that have Yomitan dictionary support.
I don't think KOReader handles fixed-size epubs terribly well too, and most of my manga (usually bought on Rakuten Kobo) comes in that format.
For reading English or native language books on non-Android e-readers it's a godsend.
BookFusion recently introduced a KOReader plugin (no affiliation). Combining that with a Kobo has finally let me break free of the Kindle ecosystem
I installed this the moment I got my Kobo Libra H2O. Mostly read fiction from the 1800s and early 1900s and I did not want to fight whatever proprietary software the reader came with (Kobo is probably better than the Kindle for this, but I never tried it!)
I have a problem with epubs though. This need to support every single thing under the sun makes the pipeline exceedingly complex. All you need for a vast majority of fiction is:
- headings
- paras
- emphasis (bold/italic)
- block quotes
Add simple "image" syntax to it to display maps etc from detective stories
Basically a ruthlessly cut down version of markdown.
The mini-readers from Xteink came in at the right time for such experimentation.
Kobo's reader definitely renders Epubs better than KOReader. I really only used it on my Kobo Libre H20 to download epubs from my calibre server. Now, on my Boox Go 7, KOReader beats the built-in reader hands down
Fiction from the 1800s? Now that sounds interesting. Can you name three titles that you would recommend? And: how did you get into this? Doesn’t sound like a TikTok trend, haha.
> Can you name three titles that you would recommend?
I can recommend some authors from the period: W Somerset Maugham, Thomas Hardy, Anthony Trollope, H Rider Haggard, Wilkie Collins, Saki, Maupassant, O Henry.
Dickens, Hugo, Austen, Eliot, Bronte, Wilde, Doyle, Poe, Melville, Verne, Stevenson, Wells, Christie, Chesterton, Burroughs, Lovecraft, Chekhov, Dostoyevsky, Tolstoy etc are probably well-known.
The list could go on forever, almost. Some books might feel dated (or too long). But that is fine.
> how did you get into this?
I started reading when I was 3-4 and never stopped. We moved to the suburbs when I was 7-8 (late 80s) and there wasn't much else to do outside of school except read. Built a physical library of close to 4,000 books along the way, but I mostly read at the computer or on e-devices
Not them, but I read Moby Dick last year. Man, I felt like I'd been lied to. It's kind of a laughing stock reference to giant old-timey books that were famous for being famous and such. So wrong! It was hilarious in parts. The narrator is a complete smartass with a strong bend to irony. I loved every bit of it, even the (in)famous chapters about whaling and knot tying and all that, which were vivid peeks into worlds I didn't know existed.
Melville's "Bartleby" is very good
I'm not familiar with it, which makes me want to add it to the reading stack.
It took me some time to know my way around it, but wow. I have it configured with some plugins, like zen ui and bookshelf. I Also use BookOrbit to sync reading progress and annotations between devices. Loving it.
Great piece of software. Jailbroken my Kindle when the UI was becoming way too slow, then discovered Rakuyomi [1] and that alone is worth the jump, especially with plugins like SimpleUI to make the UX better

KOReader is so much better, including in how it renders typography and does typesetting than what ships on Kobo devices by default, it's sort of wild.
I actually made a mod to try to upgrade Kobo's built-in reader so it's more correct, i.e. more faithful to how KOReader renders text. Sharing it here since it may be interesting for anyone with Kobo e-readers: https://github.com/nicoverbruggen/NickelTypeFix
Nico, while I have the chance, I'd like to thank you for all your work on Kobo mods and fonts
I use it because it supports opds and old Android versions (I have an old Android eBook reader). I host my books on calibre web and never need to do anything beside opening the opds section on koreader and picking what to read.
For anyone with a Kobo who only wants to be able to sync with calibre-web without installing anything on your device, here's a link to instructions:
https://jccpalmer.com/posts/setting-up-kobo-sync-with-calibr...
I'm not associate with this person, just know that these instructions worked for me.
I love KOReader on Android, but unfortunately it requires granting permission to manage all files on the device. I would prefer if it used the approach most apps use, which is to select a folder on the device that it can access. Then I can move all my books into that directory and KOReader would not have access to all of the data on my phone.
KOReader is awesome and it's my go to for most e-reader reading. I've recently been trying out Plato (https://github.com/baskerville/plato) as well and it has a really nice experience for reading PDFs. It crops the margins and pages through the PDF in chunks nicely.
If you have a newer Kindle and some hacking skills, consider looking for new Kindle jailbreak methods. The existing jailbreak methods don't work on newer firmwares. ( See https://kindlemodding.org/kindle-models.html )
I have a kobo ebook with [plato](https://github.com/baskerville/plato), it includes koreader but I found the built in mupdf much more intuitive and elegant.
The thing I find the most valuable on KOReader is something I haven't seen mentioned yet: the book map[0]
It shows you chapter and section divisions in a single screen, along with black bars to show you which pages and chapters you've spent a lot of time on. I use this very often to jump back to pages or chapters, or look at which parts confused me. It also visualizes where bookmarks and notes are. When you want to see a segment in more detail, you click there and it brings you to a 6-page zoomed-in view.
Let alone being more useful than the Kindle or Kobo UX, it's more useful than the book UX.

So good. I've built a plugin for it to allow me download books from my Jellyfin server on my Kindle 3 Keyboard (from 2010!). Was lovely for develop for and the wide compatibility of KOReader has made it a great investment.
No Windows? Is it a political choice or is there a technical limitation?
Windows would be a whole different build target, and Koreader works great through WSL anyway.
Any macOS builds out there? I would really like to have one app that can open both ePubs and pdfs.
Don’t need the library feature to manage books like Books.app, just need a light and reliable reader.
Did anyone made a comparison across different devices for running this? I am curious on what is the best device today to run it, and also the best when accounting for cost of the device too.
I love KOReader! I use it on my Kobo Clara Colour with Calibre. Love Wikipedia lookup, customization options, and the fact that wifi is off by default.
I use it since years on my PocketBook Touch HD 3. I especially like the statistics. You might not care about them, but I find them very interesting.
If you like the statistics you might enjoy BookOrbit. I'm a sucker for stats like this and love having them centralized so that it's not just on my e-reader (in case it dies or if I read on another compatible app that syncs progress/stats).
I installed this because I wanted the sqlite database that track when I'm turning each page
FWIW not only it is in itself nice but it evens has plugin system. Consider extending it and sharing back with the community!
My wish is to see ebooks become first class citizens on all digital devices. Apple has a native ebook reader built in to their devices. It's cumbersome and bloated, but it's there. No web browser except Yandex has built in ebook support, even though it would be the easiest thing in the world. Android, Linux and Windows have no built-in ebook reader, as far as I know.
Murasaki [1] is the most performant and sleek ebook reader you can get for MacOS currently. It's magnificent, but the creator has regionally limited who can get it, unfortunately.
[1] https://genjiapp.com/mac/murasaki/index_en.html
The old Microsoft Edge had epub support, and even a nascent ebook shop and a nifty note-taking/annotation mechanism (there was even a restitution payment made for folks who had taken notes), but Microsoft gave up on it when they shifted to a rebadged Chrome.
I really appreciate you mentioning Murasaki - thank you. I've been looking for something like this for a long time, because every single EPUB "reader" out there does so much more than just read EPUBs. This one does just that, I love it.
to be honest, I use the calibre ebook viewer without bothering with calibre itself (so far) and I find it to be good at what it does
I'm also using Calibre, but the ebook viewer is really clunky, I'm not a big fan.
To be fair, desktop linux doesn't really have built-in anything (except what's appropriate for a kernel, like filesystems and a TCP stack...). Many linux distributions package epub readers (calibre, okular, fbreader, bookworm), and they tend to be really easy to install.
It doesn’t seem like it’s a huge ask imo, and I’m also pretty surprised that they have such limited support, a mostly text format like epub really should be simple to add functionality for.
Less surprising but still annoying is how many hoops you need to jump through to get a good reading experience for manga, particularly on macOS. I had to try many options that were either too buggy, too difficult to install correctly, various aggressive paywalls, or straight up don’t function with high quality scans.
Eventually I landed on one(will edit the name in when I have access to my laptop) that functions well but has some memory issues in importing books, possibly a memory leak.
Maybe I’ve just become shit at finding apps in the modern unsearchable age, but it really feels like reading of all types has diminished enough that we are an unserviceable market.
*The software I landed on is Koodo Reader
I installed it and I use Calibre to send books over wifi. Simple and sweet setup.
KOReader my king
I use KOReader on everything except e-ink devices.
Linux desktop. MacOS laptop. Android tablets. Android phones.
Where-ever I am, I can pick up a device and continue reading from where I left off. I have the same config everywhere (it would be nice to be able to distribute that) for gestures and taps. I use the same font everywhere (TeX Gyre Pagella, which is a Palatino clone.)
Customization begets comfort.
Why not on e-ink devices too?
Because I don't own any that I want to use.
I always have a phone, a laptop, a tablet or a desktop to hand. The tablet is a great device for reading comics as well as books. The phone is a terrible device for reasing comics, but fine for books.
I installed it on my Kobo to have the syncing from Calibre. Works perfectly, no complaints.
Use it both on my phone and on an eink Android tablet. Love it, especially the dark mode.
I wish you could disable fullscreen (enable the navigation bar) on Android though :-(
Amazing software. Makes a 10 year old Kindle of the best electronics I own.
It seems there's a native dictionary. How does it fare?
Good. You can install your own or download the free ones from settings.
It also searches Wikipedia.
Does it have Kindle X-Ray like features, like integration with Wikipedia or possibly integration with AI for contextual information?
Yes, Wikipedia is included, and there are plugins for AI tools.
I run this on a pinenote, and I love it. Only sad thing is that I started transitioning to Linux and then lost interest, so I've only got about 8GB for data on the Android partition. I use syncthing to sync a folder with my laptop, so I just push a pdf into the folder on the laptop and then it turns up on the pinenote in koreader.
The PDF support is just the right thing to have.

Koreader rocks indeed
KOREA!
It really does rock.
Thank you for this
