Three transcripts a day on the free plan, up to 30 minutes each.

What you get

  • Word-level timestamps, so subtitle splitting lands exactly on the word.
  • Speakers separated automatically, with names you can set once for the whole transcript.
  • SRT and VTT subtitles in the language of the recording, on every plan.
  • AI summaries and other documents can be written in French or in any other of the hundred languages, whatever the language of the recording.

A real result from SonaFact

On 2 October 2026 we ran the first 75 s of a public recording in French through SonaFact. This is the beginning of the result exactly as it came out, with nothing corrected. The recording is one person reading a Wikipedia article, so the transcript has one speaker.

Three steps from recording to finished work

  1. Upload anything recorded. Audio or video — up to 30 minutes per file on Free, 3 hours on Starter, 6 on Pro and 10 on Studio. The language and the number of speakers are detected for you, or you set them yourself when you already know. You can also record straight in the browser.
  2. Review in the editor. Play it back with the line highlighted, fix a word, rename a speaker everywhere, move a line to the right person.
  3. Turn it into finished work. Export DOCX or PDF, generate minutes, action items, subtitles, chapters or a call report.
