Its main editor adds an AutoSubtitles.com watermark to free exports, up to 720p. Its simple editor exports without one, up to 480p. Captions Generator’s free videos also carry a small watermark, up to 1080p, and its subtitle files have none.

Is it faster than AutoSubtitles?
A little. In our October 2026 test the same video became a captioned MP4 1.7 times faster here. Both send only the audio and make the video in your browser. See the speed test →
Is my video private?
Yes. Your video never leaves your device: captions are drawn and the video is exported in your browser. Only the audio is sent to make captions, and we don’t keep it. We keep the transcript for 30 days to check accuracy, then delete it. Want to check? Open your browser’s developer tools, go to the Network tab and add a video: the only file sent is the audio, never the video. Privacy policy →
