A quieter phone.
A conversation away.
PeterOS is an open-source Android project built around Peter, a personal AI assistant designed to run on your phone.
Design stage · Apache 2.0 · No downloadable build yet
Why PeterOS
Start with a conversation
A chat launcher with text input, voice, and slash commands instead of an app grid.
AI that stays on the phone
Local wake word, speech recognition, one assistant model and speech output, with no cloud AI fallback.
Everyday actions, simply
Open apps, call contacts, draft messages, set alarms and adjust supported settings.
You stay in control
Review messages before sending, see when the microphone is on, and inspect an on-device log.
Minimal by design
Essential phone apps, a monochrome interface, no ads, no subscriptions, no camera in Peter.
Built for modest hardware
Simple commands run without a language model; heavier AI loads only when needed.
Design preview
Illustrative mockups of the planned lock screen, chat home and voice mode — not screenshots of working software.
Good evening, Gokul.

PeterOS is in planning and design. Features and performance figures are goals to implement and validate. The first proposed device is the Poco M4 5G with 6 GB RAM, and compatibility still needs verification.
