CaptionBolt is an AI-powered caption generator designed for short-form video creators. It transcribes speech from uploaded videos, applies timed and styled captions from a library of 308 styles, and preserves the original video framing by default. Users can edit caption text, adjust styling, resize or trim the video, and add optional elements like b-roll, cover frames, and brand assets. Finished projects can be exported as MP4 or subtitle files, along with AI-generated social media post copy for TikTok, Instagram Reels, and YouTube Shorts.
