Windows overlay coding agent — double-tap Alt to bring your current selection, files, and workspace to AI (DeepSeek).
AltAltAi is a local Windows desktop overlay. It captures context from the foreground app, then runs a DeepSeek agent that can read and edit files, run Shell, use MCP tools, and search the web — without leaving the window you were in.
- Download the MSI from Releases
- Open Settings from the tray and add your DeepSeek API key
- In any app, double-tap Alt → type → Enter
Requires Node 18+, pnpm, Rust stable, VS C++ Build Tools, and WebView2.

API keys and settings live in the local app data directory. Chats are local by default. Workspace files leave your machine only when you send a turn to your configured DeepSeek endpoint.
