Tiny uses the least memory. Base and Small may improve recognition but need more memory and time. Try a short sample first. No accuracy or speed is guaranteed.
Audio is processed locally. Model files download from Hugging Face when you start, then stay in your browser cache when storage permits. How privacy works
Your transcript
Click a word or timestamp to listen. Search updates as you type. Edit text and add speaker names yourself. Speaker recognition is not automatic.
Shape your subtitles
SRT and VTT exports use this layout. These controls limit characters and lines, not reading speed. Check subtitle reading speed before publishing.
Saved on this device
Recordings and edits are stored in this browser when local storage is available. Export an important transcript before clearing browser data. The delete control clears app storage and its model cache. Use browser cache controls to remove any browser-managed download copies too.

Generate, listen, correct
Choose the spoken language, start transcription and review the draft. The export selector includes SRT and VTT. A model transcript does not reliably identify speakers or describe meaningful sounds. Add that information yourself when preparing accessibility captions.
These are separate subtitle files. The tool does not burn text into video. Test the export with the exact final video, especially after cutting or adding an intro.
