From raw video to captioned video, automatically
Most subtitle tools hand you a file and leave the hard part to you. This one delivers the finished product. The AI hears the speech, writes it out as readable subtitles, and renders them onto the frames — so the video you download already has captions on screen, no editing pass required.
- 01
Upload your video
Drop in the clip that needs subtitles — long-form interviews and short clips both work. No subtitle file required.
- 02
AI transcribes and subtitles
The AI listens to the spoken dialogue, transcribes it into accurate subtitles, and burns them directly into the video picture.
- 03
Preview and download
Watch the captioned result right on the page, then download a finished MP4 with the subtitles baked in.
Upload a video, get a captioned video back
nothing else to assemble.
Subtitles are burned into the picture, so they display anywhere the video plays.
Preview the captioned result on the page before you download it.
Captions that play everywhere
Because the subtitles are rendered into the video itself, they show up the same way on every platform and player — no upload form to fill, no sidecar file that might go missing. Post the captioned MP4 to social feeds where most viewers watch with the sound off, and the words are already there on screen.

Frequently asked questions
What do I get back — a file or a video?
A finished video. The AI transcribes the dialogue and burns the subtitles into the picture, so you download a captioned MP4 ready to preview and share — not a separate subtitle file.
Do I need to upload a subtitle file?
No. You only upload the video. The AI listens to the spoken dialogue itself, generates the subtitles, and renders them onto the frames automatically.
Can I preview the result before downloading?
Yes. The captioned video plays right on the page, so you can check how the subtitles look and read before you download the final MP4.
Does it need a video, or can I subtitle just an audio track?
It works from the speech in your source, so a voiceover or audio track is enough to generate the subtitles. This fits the Recapo recap workflow, where you can subtitle an AI voiceover before the visuals are finalized.
