What people ask us
Does it download the video?
No. You watch the video on YouTube as usual; WatchTranslate only translates what is playing.
What if the video already has automatic captions?
Even better: they are put back into full sentences and then translated. It is faster, and your minutes last five times longer.
Does it only work on YouTube?
No. It also works on X, Bilibili, TikTok, Instagram, Dailymotion and other video sites, and on video files you already have.
How good is the translation?
It is done by AI from the audio or the captions. You can follow it easily; some proper names may vary from one part to another.
Which devices does WatchTranslate work on?
On phones, the Android and iPhone apps. On computers, the Chrome or Edge extension for online video and the Windows or Mac app for video files.
