Sunday
A personal AI you self-host: one chat across voice, text, iMessage, desktop, and satellites installed on your own machines.
Sunday is the personal AI idea pushed all the way into infrastructure: one conversation, self-hosted, with every modality feeding the same context. Voice, text, iMessage, desktop, and satellites are surfaces — not separate bots.
The daemon owns the chat log. Satellites on machines dial home and expose useful capabilities like shell, screen, browser control, and on macOS, iMessage. The data sits in SQLite, and Litestream can replicate it so the whole thing stays simple without being fragile.
The goal is a personal AI that is actually yours: memory, tools, machines, and context under your control.
It is open source, because the whole point is ownership. The repo is linked in the sidebar.
