CaptionBolt

CaptionBolt is an AI caption generator and finishing tool that turns your recorded talking-head videos into publish-ready short-form content. Instead of wrestling with manual captioning, it automatically transcribes your speech into timed, editable captions and applies customizable styles, so every clip looks polished in minutes.

By default, CaptionBolt preserves the original video framing, so your footage stays exactly as shot. You stay in control of accuracy: review and correct every word of the transcript, and resize or crop the video whenever a different aspect ratio is needed.

Finishing touches are built in. Optionally trim the beginning or end of your footage, then add covers, B-Roll, logos, progress bars, and ready-to-use social post copy — all in one place. When everything looks right, export the finished video with subtitle files, with export options depending on your plan.
