Use cases
Captions for every platform, and every file.
Short-form video, professional posts, podcasts and courses need captions in different shapes. Start from what you're making.
By platform and job
- Auto caption generatorUpload a clip and AutoCap writes the captions for you — each word timed to the moment it's spoken, ready to correct, style and export.
- Subtitle generatorAutoCap transcribes the speech in your video, times every word, and hands you the tools to turn that transcript into subtitles that are easy to follow.
- Add subtitles to videoEverything happens in a browser tab: the transcript, the corrections, the styling and the final render of your subtitled video.
- Burn in subtitlesBurned-in subtitles are drawn into the frames of the video itself, so no player, app or viewer setting can hide or restyle them.
- TikTok captionsCaptions timed to each spoken word, animated as they're said, and positioned where TikTok's interface won't sit on top of them.
- Instagram Reels captionsStyle captions once, keep them out from under Instagram's buttons and text, and export a vertical MP4 that's ready to share as a reel.
- YouTube Shorts subtitlesBurn captions into the Short so they show in the feed, then upload the matching SRT in YouTube Studio so the words also exist as a caption track.
- LinkedIn video captionsUnderstated captions for a feed where video can start playing silently, plus the SRT caption file LinkedIn accepts when you share from a desktop.
- Podcast clip captionsPick the moment, cut it out, and give it captions that break cleanly when the speaker changes and lean on the words that carry the point.
Subtitle files
- SRT generatorAutoCap transcribes your video, lets you correct every word and timing, and writes a clean SRT file from the result.
- VTT generatorAutoCap transcribes your video, lets you fix every word and timing, and writes a valid .vtt file with the WEBVTT header already in place.
- Closed caption generatorAutoCap turns the speech in your video into an edited caption file that players show whenever a viewer asks for captions.
