What people use this for
Interviews and research
Get a searchable transcript before you start pulling quotes. Reading is faster than scrubbing a waveform.
Meetings and calls
Turn a recording into notes you can skim. The free tier has no speaker labels (Unlimited does), but the content is all there.
Lectures and study
A transcript is searchable in a way a two-hour recording never is — Ctrl+F beats rewinding.
Video subtitles
Export straight to .srt with timestamps already cued for your editor.
Going deeper
Starting from an MP3 specifically, need subtitles instead of a transcript, or want this running in code? And if you're weighing hosted transcription against the OpenAI API, here's the per-hour maths.
FAQ
How do I convert audio to text?+
Drop an audio or video file into the box above and click Transcribe. The file uploads, the model runs, and the text appears — typically within 5 to 15 seconds. You can copy it, download it as .txt, or export timestamped .srt subtitles. There's nothing to install and no account to create.
How accurate is automatic transcription?+
On clear single-speaker audio, Whisper large-v3 lands close to verbatim — good enough that editing is faster than typing from scratch. Accuracy degrades predictably with background noise, distance from the microphone, strong accents and people talking over one another. Nothing at any price is reliable on a phone recording from across a room.
Which languages are supported?+
99 and change, detected automatically — you don't pick one. That includes code-switching, where a speaker moves between languages mid-sentence. If you want a non-English recording turned into English text rather than transcribed in its own language, that's the translations endpoint on the API.
Is it really free, and what is the limit?+
3 files a day per IP, resetting every 24 hours, with a 15 MB cap per file. Files up to 15 minutes show on screen; 15 to 30 minutes are emailed to you. No account, no card, no expiring trial credits.
What file types work?+
mp3, wav, flac, m4a, aac, opus and ogg for audio; mp4, mov, webm and mpeg for video, where the audio track is extracted automatically. If ffmpeg can decode it, it will work here.
Can I tell who is speaking?+
Not on the free tier — it returns one continuous transcript. Unlimited ($9 a month) labels each speaker in the transcript. Word-level timestamps are on the paid API.
