Subtitles that fit your video
SRT and VTT formats
SRT is accepted by most video editors and players, and VTT is the standard for web video. Both are available from one transcript on the paid plan.
Control over line length
Limit the words, characters and seconds per subtitle so the lines are easy to read on screen. Sentence-aware splitting avoids cutting a sentence in an awkward place.
Accurate timing
Timestamps come from the recording itself, so the subtitles follow the speech instead of being spread evenly across the video.
Edit before exporting
Correct names, brands and terminology in the editor first, so you do not have to fix the subtitle file by hand afterwards.
Podcasts, courses and interviews
Add captions to audio-first content published as video, and make it accessible to viewers watching without sound.
10+ languages
Create subtitles in English, Spanish, French, Portuguese, Chinese, Hindi, Arabic, Urdu, Russian or Ukrainian.
