Speak, and it appearswhere your cursor is.

Hold the shortcut, talk, let go. Speech recognition and cleanup run on your PC, and the result is typed straight into the app you are already using.

Right Althold to talk

Free to start · No account needed · Works offline once models are downloaded

Holding Right Alt and speaking brings up the recording capsule at the bottom of the screen, which shows your words as you say them. When you let go, the sentence is cleaned up and typed at the cursor in the notes window. The example repeats.

A scripted example, not a real recording.

From quick notes to meeting minutes, all on your PC.

Everything below is free and, with the default settings, runs on your own machine.

  • Type by voice anywhere

    Works wherever there is a cursor: notes, browsers, code editors, chat apps. Press the shortcut twice to keep talking hands-free.

  • Text cleanup

    Removes filler words and tidies up sentences with a local Ollama model. You can also create your own commands, such as translate or summarize.

  • Next-sentence suggestions

    While you write, a local model offers ways to continue. Pick one with Ctrl+Alt+Up/Down and insert it with Ctrl+Alt+Enter.

  • Live captions

    Shows captions on top of your screen for meetings, lectures, and videos. Finished lines are corrected once more using the lines around them.

  • Meeting notes

    Records long meetings and, when they end, writes up a summary and action items.

  • File transcription

    Drop in an audio or video file and get a transcript with timestamps.

Hold, speak, release. Done.

No switching windows. It all happens where you were already typing.

  1. Hold

    Recording runs while you hold Right Alt. You can change the shortcut in Settings.

  2. Recognize

    The built-in faster-whisper engine turns speech into text. An NVIDIA GPU makes it faster.

  3. Clean up

    If enabled, a local model tidies or translates the text. Turn it off to keep exactly what was heard.

  4. Type

    The text is pasted at your cursor. Whatever was on your clipboard is put back afterwards.

By default, it stays on your PC.

There are cloud features, but they are not used until you turn them on.

Speech is processed on your PC
The default speech recognition uses a local engine, and recordings and history are stored in a database on your PC.
No account required
Every local feature works without signing in.
Usage analysis is off
Typing-pattern analysis only turns on with your consent, and even then the results stay on your PC.
The cloud is opt-in
If you turn on cloud speech recognition (with your own API key) or cloud text cleanup (sign-in required), only those requests are sent to an outside server.
