What you may want to ask first
Can it translate online Japanese videos?
Yes. Add the WatchTranslate extension to Chrome or Edge on your computer, open the video and click the WT icon in the player. YouTube, X and Bilibili have dedicated support. On other sites you can try translating from the extension; results depend on the site.
Which languages can the subtitles be in?
74 languages, including English, Spanish, French, Portuguese, Chinese and Korean. You can also show the original and the translation together.
Does it work on my phone?
Yes. On Android and iPhone, download the app. On other phones, open the local player in your browser.
Is my video uploaded to your servers?
No. The video file stays on your device. To recognize speech, the audio segments needed are sent to the server.
How accurate is the translation?
Usually good enough to follow the story, but it is AI translation. Names, dialects, overlapping speech and loud backgrounds are more error-prone, and it won't match a carefully checked fansub.
What if my file won't open?
Very large files or unusual codecs may not open. Try the WatchTranslate app, or convert the video to MP4.
