From MP4 video to editable text

HeyCaptions extracts the audio from your MP4, transcribes it with a modern speech recognition model and gives you clean text to paste into a document, blog post or email. Turn on timestamps to see when each paragraph starts.

You can also correct words in the Text tab, export subtitles, or add captions to the video itself with one click.

Works with phone and screen recordings

Videos from iPhone and Android, screen recordings, webinar exports and camera files all work. MOV, WEBM, MKV and AVI are supported too.
