About the subtitles

Subtitles are made from the same word timings as the transcript, so each line appears when it is said. Lines that run too fast to read are flagged before you download. Paid plans can also translate the subtitles into other languages.

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.
