Automatic from start to finish

Transcription, timing and line breaks happen automatically, and the spoken language is detected for you. You only step in to fix a word or change the style.

Captions that hold attention

Word-by-word caption styles keep sound-off viewers watching. Start from a preset, then adjust the font, size, outline, position and words per line.

Free to start, cheap to scale

Answers

Frequently asked questions

Is the subtitle generator free?
Yes. Your first 3 subtitled videos are free and download without a watermark. No credit card is needed. After that, each video costs 5 credits (up to 5 minutes) or 10 credits (up to 10 minutes) on a paid plan. The free plan is not offered in every country.
What does 'automatic' mean here?
Transcription, line breaks and timing are all generated by AI without manual input. You only review and style if you want to.
Can I edit the captions?
Yes. Every word in the transcript is editable, and you can change the caption style before you export.
What languages does it support?
oVideo detects the spoken language automatically and writes the subtitles in that language. It does not translate subtitles into other languages.
How long can my video be?
Up to 10 minutes and 1 GB, as an MP4, MOV or WebM file.
Can I download an SRT file?
Not yet. oVideo burns the captions into the video and exports an MP4, which is what TikTok, Reels and Shorts need.
Will captions help my reach?
Most social video is watched on mute, so on-screen captions typically improve watch time and completion rate.
