oVideo's AI caption generator creates, syncs, and styles on-screen captions for every video automatically — no manual timing, no transcript upload, no caption software required. Generate your video and captions arrive synced and styled in the same step.
Most video tools require a separate captioning step — upload the video to a caption tool, generate the transcript, sync the timing, download, and re-import. oVideo generates captions in the same step as the video itself.
oVideo's captions highlight each word as it is spoken — the same caption style proven to increase video completion rates on TikTok and Instagram. Viewers reading along are significantly more likely to watch to the end.
