Jenny: An Open Source On-Device AI Assistant Replacing Your Home Screen
flagdizero · reddit · 2026-08-28
The author developed Jenny, a personal AI Agent running entirely on-device (via an embedded Python runtime) on a Titan 2 phone with a physical keyboard. The app replaces the home screen interface, launching a conversation when the Home key is pressed, while also functioning as a standard application.
Jenny features memory capabilities, executes scheduled tasks while the screen is off, and can generate its own mini-apps upon request. The author highlights that on a device with a physical keyboard, users can start typing immediately without tapping an input field. The project is open-source on GitHub and has been the author's daily driver for a month.
