FAQ
Which languages are recognised?
The model is multilingual and detects the spoken language by itself. If it guesses wrong, pick the language from the list before you drop the file.
Does it work offline?
Yes, once the speech model has been downloaded. The first visit fetches it and your browser keeps it; after that, transcription needs no network at all.
Why is it free, and what is the catch?
Your computer does the work, so there is no server bill to pass on. The catch is speed: it depends on your device. The check further down shows what to expect from yours.
How do I check a word I am not sure about?
Click the line it is in. The recording plays from there, and the line stays highlighted as the audio moves on.
Is it suitable for confidential interviews?
Yes — the recording is never uploaded, so it never sits on anyone else’s server.
