Vocnu

AI voice-over and subtitles for any video, in 35 languages

Vocnu translates video into 35 languages with a natural AI voice-over and subtitles. Use the browser extension for Chrome, Brave and Edge to watch YouTube videos and online courses in your language, or upload a file in the web app and download the dubbed video, the voice-over audio or just the subtitles. The new voice sits over the lowered original sound, so the music and effects stay. You see the price before you start and pay per minute; new accounts get 40 free credits.

Hi everyone! Vocnu translates a video into 35 languages with an AI voice-over and subtitles. The browser extension works right on YouTube and other video sites, the web app takes any file you upload, and there is an MCP server if you'd rather ask Claude to do the dubbing. The original sound stays under the new voice, and you see the price before anything starts. New accounts get 40 free credits, so you can try it on your own video. I'd love to hear which languages and voices work well for you and which don't.
