Hold
The notch blooms out of the top of your screen. Your words appear as you say them.
Voice assistant for Windows
FluidUI lives in a notch at the top of your screen. Hold Ctrl Alt, talk, let go — it listens, thinks, answers out loud and gets things done on your PC.
Live demo — the real notch, rebuilt with the same spring physics.
How it works
The notch blooms out of the top of your screen. Your words appear as you say them.
FluidUI thinks with DeepSeek and picks the right tool — an app, a file, your inbox, the web.
One short sentence, spoken in a natural voice that runs on your own PC. Then it folds away.
Takeover
Opening the reservation page and filling in the guests…
Highlight
The screen dims around what you asked for — it points, it doesn't touch.
Asks first
Sending mail, moving files, adding events — FluidUI shows a card that grows right out of the notch, one continuous shape. Tap Send, or Cancel. Deletes only ever go to the Recycle Bin.

Private by design
Speech recognition runs on your own GPU with Whisper. Audio is never uploaded.
Replies are spoken by Kokoro, a voice model that runs entirely on your machine.
When FluidUI looks at your screen, its own notch is hidden from the capture. Your screenshots still see it.
Google sign-in happens in your browser; FluidUI never sees your password. Tokens stay on your PC.
Coming soon
We're putting the finishing touches on it. FluidUI is coming soon to Windows.
Coming to Windows 10 and 11
