Turn speech into text and subtitles with Whisper running entirely in your browser. The recording never leaves your machine, which matters most for exactly the recordings people need transcribed: interviews, meetings, dictation, legal and medical audio.
How it works
- Drop an audio file or a video, and the audio track is decoded on your device.
- Pick a model: Fast (≈41 MB, downloaded once) or Accurate (≈77 MB).
- Transcribe, watch the text appear live, and download .txt, .srt or .vtt.
Questions
- Does my file get uploaded?
- No. The models and all processing run inside your browser on your own device. You can verify this yourself: open your browser’s DevTools, watch the Network tab, and process a file: there are no uploads. After the first visit most tools also work fully offline.
- How accurate is it?
- The models are OpenAI’s Whisper (tiny and base tiers). On clear speech they are very usable; heavy accents, crosstalk and noisy rooms will show errors. The Accurate tier is noticeably better on difficult audio.
- Which languages work?
- The models are multilingual, and transcription currently runs in English. More languages are planned: the model itself already supports 99.
- How long does it take?
- On a machine with a supported GPU, a few seconds per minute of audio. On CPU-only machines it is slower but still practical, around a quarter of the recording’s length.
