Animated captions that stay in sync after every cut
Quick answer
MirrorCut generates captions from your speech and ties them to the audio, so they stay in sync after every cut, whether you make it or the AI agent does. Choose from 48 animated styles, highlight the words that matter, and export SRT or VTT caption files at any point.
Most viewers watch Shorts and Reels with the sound off, so captions decide whether a clip gets watched. But captions made before the final edit break the moment you trim a pause or move a clip.
MirrorCut generates captions from your speech and keeps them tied to the audio, so they stay in sync through every cut, by you or by the agent. Pick from 48 animated styles, highlight key words, and export caption files when you need them.

What MirrorCut does
48 animated caption styles
Word-by-word captions in eight families, designed for Shorts, Reels and TikTok, from clean subtitles to bold hero words.
In sync after every cut
Captions follow the speech through every trim and cut, by you or by the agent, so editing never breaks them.
Key-word highlights
Ask the agent to emphasise the speaker's key words so the message lands even without sound.
