WatchTranslate

WatchTranslate shows original and translated subtitles together, right on the video. When a video has captions, it translates them; when it has none, it transcribes the speech and translates that. It translates as you watch — jump anywhere and it starts there, no waiting for the whole video. Works on YouTube, X and Bilibili through a Chrome extension, and on your own video files in the browser at watchtranslate.com/player. 74 subtitle languages, SRT/VTT export, free to start.
