COMPANIONS

Meet Max.

Your AI companion comes with a pixel art pet that lives on your desktop.

Sato sprite: Max the Samoyed, idling

A cheerful Samoyed with white wings. Walks beside you, flies to help, and barks when he gets it right.

    Paris

FAQ

Questions.

Is it free?

Yes, Sato is free and open source. You pay Anthropic directly for API usage, which typically costs pennies per question.

Does it work on Windows or Linux?

macOS only right now (14.2 or later). If there's enough interest, cross-platform support is on the roadmap.

Is my screen data private?

Your screenshots go directly from your machine to Anthropic's API. Sato doesn't have a server and doesn't see your data.

Can I use my own Claude API key?

Yes, Sato uses your own Anthropic key stored securely in macOS Keychain. No middlemen.

Who built this?

Amir Valizadeh, a CS student at the University of Pittsburgh. Inspired by Clicky by Farza Majeed.

Can I add my own sprite?

Custom sprites aren't in the UI yet, but the app is open source — the sprite system supports new characters with a simple folder structure.
