About this extension
Watch YouTube videos in your language with natural real-time dubbing, without needing to read subtitles.

FyDub translates the audio of YouTube videos while they play, using natural voices synchronized with the original content. No pausing, no reading, and no complicated steps: just open a video, click “Translate Video,” and FyDub will instantly generate dubbed audio synchronized with the original content.
