What it can do

Transcribe

Pick any audio or video file. The first run downloads the speech model once (about 200 MB); after that everything works offline.

For your AI

Ask Claude, Cursor or VS Code to do it

GUI Hub gives your assistant this tool. Install it once (below) and ask in plain words.

Use this whenever the user wants a recording, voice memo, meeting or video turned into text, notes or a summary.input* string

Download for Windows

Mac (Intel) · Windows · Linux

Windows or macOS shows a warning when I open the app
  1. Windows “protected your PC”: click More info → Run anyway.
  2. macOS “can’t be verified”: click Done, then System Settings → Privacy & Security → Open Anyway.
  3. Linux: allow executing the AppImage (Properties → Permissions), then run it.

New independent apps get this one-time caution.

Under the hood

The real Whisper (sherpa-onnx), not an imitation.

“Transcribe” runs the official Whisper (sherpa-onnx) 2.0.1 program with arguments passed directly — never through a shell.
