Marvis
A privacy-first AI co-pilot that lives on your desktop
Marvis is an always-available assistant that floats above your workspace as a small translucent bar. It can see your screen (with your permission), hear your meetings, answer questions about what's on screen, and stream responses into an overlay panel — all while keeping your API keys, history, and screen data entirely on your machine. No accounts, no cloud sync, nothing leaves your device except the requests you send to the providers you choose.
Tauri 2 + Rust + React — the Rust core owns all sensitive logic
(capture, audio, keys, storage) and the webview is UI only.
