AI Video Translator: Captioner

Captioner is an AI video translator: it turns a video in a language you don't speak into one you can watch in your own.

Choose a video from your photo library — Captioner transcribes the speech, translates it, and plays the video back with captions in your language, plus an AI summary of what it says.

Any language in, any language out: Thai speech to English captions, English to Burmese, Chinese to Vietnamese — every direction works.

No account. No editing skills. Start with five free videos.

HOW IT WORKS

1. Choose a video from your photo library
2. Choose your language — 100+ supported
3. Watch with translated captions, or skim the AI summary first
