About This Software

Companion OS brings a customizable 3D AI companion directly to your Windows desktop.

Chat naturally, talk using your microphone, play mini-games, listen to music, manage notes and reminders, start focus timers, and use handy desktop tools — all without leaving what you're doing.

Choose your companion and personality, then make them your own. Your companion can stay quietly by your side while you work, browse, study, or play games, and jump into a conversation whenever you want.

Use supported cloud AI providers for fast responses or run local AI models directly on your PC for a more private, offline-friendly experience. With optional Desktop Vision, your companion can even look at your screen when you ask and respond to what you're seeing.

Companion OS is designed to feel present without getting in the way — part AI assistant, part desktop companion, and part cozy place to hang out.
