Voice assistant for Windows

Say it. It's done.

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

Three moves.
No window to open.

Hold

The notch blooms out of the top of your screen. Your words appear as you say them.

Let go

FluidUI thinks with DeepSeek and picks the right tool — an app, a file, your inbox, the web.

Listen

One short sentence, spoken in a natural voice that runs on your own PC. Then it folds away.

Takeover

It can drive
your computer.

  1. "Take over and book a table for two tonight."
  2. The edges fade to black — FluidUI is in control.
  3. Its own pointer, labelled. Yours stays where you left it.
  4. It clicks, types and checks every step on screen.
  5. Press Esc any time. Done — it tells you so.

The screen dims around what you asked for — it points, it doesn't touch.

Asks first

Nothing happens
without your yes.

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.

40+ tools

One voice.
Everything on your PC.

Private by design

Your voice
stays on your PC.

01

Local ears

Speech recognition runs on your own GPU with Whisper. Audio is never uploaded.

02

Local voice

Replies are spoken by Kokoro, a voice model that runs entirely on your machine.

03

Invisible to itself

When FluidUI looks at your screen, its own notch is hidden from the capture. Your screenshots still see it.

04

Your keys, your mail

Google sign-in happens in your browser; FluidUI never sees your password. Tokens stay on your PC.
