AI subtitles you can still edit like a human.

How it works
- 01
Choose a video
Upload the clip from your browser and let the app prepare its audio for transcription.
- 02
Generate timed text
AI converts the speech into caption segments with timing for each spoken word.
- 03
Correct and design
Review the transcript, adjust line breaks, and apply a caption style on the video.
- 04
Export the result
Download a captioned MP4 or a subtitle file for another editor or platform.
Built for the correction after generation.
Word-aware motion
Caption styles can emphasize the current word because the transcript includes detailed timing.
Human review is expected
The product makes correction part of the normal path instead of pretending transcription is infallible.
Questions before upload
What does the AI subtitle generator do?+
It transcribes speech from a video, creates timed caption segments, and opens them in an editor for review and styling.
Can I correct AI-generated subtitles?+
Yes. You can edit the wording and work with caption timing before exporting.
Can I export a subtitle file instead of a video?+
Yes. SRT, VTT, and TXT downloads are available alongside burned-in MP4 export.
Does the AI-generated video have a watermark?+
No. Neither the Free nor Starter plan adds a watermark to the exported video.
