Sten

On-device voice-to-text for Mac.

Stop typing. Start talking. Voice-to-text for Mac, running entirely on-device — no cloud, no subscriptions, no leaving the keyboard. Works in every app, 25 languages, free forever.

Sten lives in your menu bar. Press a hotkey, speak, and your words are typed into whatever app is focused.

Usage

  1. Launch the app — it appears in the menu bar
  2. Complete the onboarding wizard (permissions + hotkey)
  3. Press your hotkey to start recording, press again to stop
  4. Text is typed into the active app

Transforms

Run every transcription through an AI Fix Speech command that fixes grammar, spelling, and misrecognized words. Powered by Tetra — enable Fix with Tetra in Sten's menu to turn it on. Enable Include Context to pass nearby text from the active app for context-aware corrections.

FAQ

Is it really free?

Yes.

Will you start charging later?

No. If you want to support me, buy a vlad.studio account.

How accurate is it?

It uses Parakeet TDT, a state-of-the-art model running on Apple's Neural Engine.

Install

Download Sten.zip, unzip, and drag Sten.app to /Applications.

For AI fixes, also install Tetra.

On first launch, Sten asks for Accessibility and Microphone access — required to capture keystrokes and audio.
