About Add subtitles

Generate subtitles from the speech in a video using on-device recognition, fix any words in the editor, then either burn the captions into the video for social platforms or download an SRT or VTT file for YouTube and players. Your audio is never sent anywhere.

  • Clear audio without music gives the most accurate transcript.
  • Burned-in captions show everywhere, including muted autoplay feeds.
  • You can also drop an existing SRT to style and burn it in.

  1. 1Drop a video or audio file and pick the language.
  2. 2Wait for the transcript, then edit lines and timings as needed.
  3. 3Burn the subtitles into an MP4, or download SRT or VTT.
