Frequently Asked Questions
Which AI model is used for transcription?
This tool uses OpenAI Whisper (tiny model) via the Transformers.js library. The model runs entirely in your browser — no audio is sent to OpenAI or any server.
What audio formats are supported?
MP3, WAV, OGG, FLAC, M4A, MP4, and WebM. Any format your browser can decode via the Web Audio API will work.
How accurate is the transcription?
Whisper tiny provides good accuracy for clear speech in English. For best results, use clean audio with minimal background noise. Longer files may take more time to process.
Is there a file length limit?
There is no hard limit, but the Whisper tiny model processes audio in chunks. Very long files (over 30 minutes) may take several minutes to transcribe.
