We just launched Silo, a personal AI app that is private by default.
We believe everyone deserves a personal AI that is truly theirs. Today, most AI apps require sending your conversations to a provider who can log, analyze, or profile your data. Our goal with Silo is to bring Signal’s privacy guarantees to personal AI, so you can use the best models without giving up control of your data.
How it works:
Open-source models (DeepSeek R1, Llama 3.3 70B) run inside NVIDIA GPUs with confidential compute mode enabled. This provides hardware-level isolation, encrypted memory, immediate deletion, and cryptographic attestation.
Closed-source models (GPT 5, GPT 4.1) run through privacy layers. Right now that means proxy routing with traffic mixing. Coming soon: a <1B parameter local anonymizer model that replaces sensitive info on your phone before queries ever leave it.
What’s included today:
Access to open-source models in TEEs, closed-source models with privacy layers
Fully local memory on your device (Postgres-backed on macOS, lightweight local memory on mobile)
afaik the app isn't open source, i'm required to login with Google/Apple, and theres very little information in the app about security, and plus, running models like DeepSeekR1 and Llama70B aren't cheap, so you've gotta be getting money from somewhere, right?

Someone needed to make this! Thanks, I'm trying it out!
Finally someone building privacy focused with taste. When OpenAI started sending chats to police was the last thing for me
Nice! I've been looking for more privacy oriented apps for a while, will give it a try for sure.
Wooooooooo
awesome!
