Audio to Text Converter
Turn any recording into text you can copy, with timed subtitles as a bonus.
Interviews, lectures, podcasts, meetings, voice notes: drop the file and get the full text. Timestamps come along, so you can also save SRT or VTT subtitles.
The transcription runs inside your browser with Whisper, the open speech recognition model by OpenAI. Your audio is never uploaded: only the model itself is downloaded once, then your browser keeps it, so the next files start right away.
Speech model: Whisper by OpenAI (MIT). Runs with Transformers.js (Apache-2.0).

FAQ
How accurate is it?
For clear speech, Whisper usually gets well over 90 % of the words right. Background music, crosstalk and strong accents lower that; the More accurate model helps there.
Is my recording uploaded?
No. It is transcribed on your device. Only the speech model is downloaded, never your audio.
Is there a length limit?
We don't set one. Long files take longer: on a recent computer with Chrome or Edge, an hour of audio takes about 10 minutes. Phones and older computers are slower.
Which languages work?
Whisper understands around 100 languages, including English, Spanish, German, French, Portuguese, Hindi, Arabic, Japanese and Indonesian. Accuracy is best for widely spoken languages.
Is it free?
Yes. No account, no minutes limit, no watermark.
