What it does

🎙️

Talk, don't click

A realtime voice agent lives at the bottom of the screen. Press a hotkey or say a wake word, then just ask for what you want.

🪟

Apps as glass windows

“Open a browser and go to YouTube.” “Open a terminal.” Windows tile themselves into a neat, resizable grid you control with your voice.

🖱️

It can drive your PC

When a task needs the real mouse and keyboard, comfyOS takes over and does it — watching the screen and acting like you would.

🌲

Calm by design

Living video backgrounds, frosted glass, and a quiet interface. Swap the whole scene by asking — “give me the Lord of the Rings background.”

🍅

Built to focus

Notes, to-dos, a music player, a pomodoro timer, weather and a clock — all on tap, all hands-free.

🔒

Your key, your machine

Bring your own OpenAI key. It’s encrypted on your device and never leaves except to call OpenAI. No accounts, no middleman.

First launch asks for your OpenAI API key. comfyOS isn’t code-signed yet, so Windows may show “Windows protected your PC.” Click More info → Run anyway.
