Our verdict

This browser extension translates and dubs online video in real time, so you listen in your own language instead of reading subtitles on YouTube, Bilibili, Udemy or Coursera. The free tier caps you at five dubbed videos a day, and options like preserving background audio or detecting multiple speakers sit behind a premium subscription. Anyone who watches lecture or tutorial video in a language they don't speak gets the most out of it, while heavy daily users will hit the free limit quickly.
