Trusted by 1,100+ performance marketers at top brands like:
Frame-accurate sync, no manual tweaking
Captions land on the exact frame the word is spoken. No more dragging timeline blocks five frames left.
Brand-styled, not stock TikTok captions
Set caption font, color, stroke, and animation once. Every ad variant uses the same caption style without redoing it.
50+ languages, accurate transcription
Auto-caption Spanish, German, Portuguese, French, and more. Switch language without retyping a single word.
One render, all aspect ratios
Captions reflow for 9:16, 1:1, and 16:9 automatically. Stay safe inside the action zone on every platform.
Test caption variations like ad copy
A caption rewrite often beats a new edit. Run caption variations through testing alongside hooks and CTAs.
Captions on every video, every render
Auto-caption fires on bulk renders, not just one-offs. Ship a hundred captioned video ads as fast as you ship one.
