Caption Generator

Caption lets you add accurate, styled captions to videos without installing anything. It runs entirely in your browser, keeping your video on your device while sending only a small compressed audio track for transcription. You can edit every word, control pacing, choose social-ready styles, and export SRT/VTT for free or burn captions into MP4. Caption supports popular video and audio formats and offers free, no-signup use with paid plans for higher-resolution, watermark-free exports.
