About this extension
Translate the audio of your YouTube videos from any language into your own — with real-time AI dubbing, no more reading subtitles.

Fydub lets you listen to YouTube videos in your own language while they play, no matter what language the original video is in. No reading, no pausing — just natural AI voices that stay perfectly synced with the video in real time.

Simply open a YouTube video, click “Translate Video,” and Fydub will instantly generate dubbed audio synchronized with the original content.
