Getting started

Set up the Somnus desktop app and run your first task in a few minutes.

What Somnus is

Somnus is one desktop chat with Claude, GPT, Gemini and 50+ other models. It picks the right model for each task, remembers you, and can act on your computer: it can use the terminal, a browser and your files, and it shows every step it takes.

Download

Somnus is available for Windows and Linux. Get it from the download page.

Windows: installer (.exe)
Linux: AppImage, .deb or .rpm
