FAQ
Is the MP3 uploaded anywhere?
No. The file is decoded and transcribed inside your browser tab. The only download is the speech model itself, fetched once from a public model host — after it has loaded you can even go offline and keep transcribing.
How long can the file be?
There is no limit. MP3 is read in small pieces, so recordings hours long still fit in memory. Speed depends on your device: with graphics acceleration it runs many times faster than real time; on the processor alone, closer to real time.
What can I export?
Plain text, with or without timestamps, or SRT subtitles with timing for every line.
Can I transcribe MP3 in other languages?
Yes. The spoken language is detected automatically, and the languages it handles best are listed below — pick one before you start if detection guesses wrong.
How fast is converting MP3 audio to text?
It depends on the device: with graphics acceleration it runs many times faster than the recording, on the processor alone about as fast. Silence is skipped, so long gaps cost nothing.
