Make your captioned video
Everything happens on your device. No upload, no sign-up, no watermark.
Drop a video here, or tap to choose
MP4, WebM, MOV — whatever your browser can play. The file never leaves your device.
Format
Trim
The preview loops inside the trim. Export renders exactly this range.
Captions
No caption lines yet. Add one at the playhead, import an .srt, or use tap-along timing below.
Tap-along timing — type lines, stamp them as the video plays
Press play, then tap "Stamp line" each time a new line begins. The last stamp closes the final line.
Dictate captions — browser speech recognition
Checking your browser…
Plays the video while listening. Works best in Chrome, speaking along or with the video playing aloud near your microphone. Lines are stamped with timings you can adjust after.
Project
Projects store captions, trim and settings — the video file itself stays where it is, so re-add it when you reopen a project.
Export
Renders your trimmed range with captions burned in and the original audio kept. WebM format, full quality, no watermark.
