Immersive Translate or WatchTranslate for videos?
Immersive Translate translates web pages, PDFs and videos; for a video without captions, its AI subtitles are a Pro feature. If video is what you translate, WatchTranslate is built only for that: it listens to the audio on YouTube, X, Bilibili and your own files.

Immersive Translate and WatchTranslate for video
Two tools with different centres, compared cell by cell; every cell links to the page it came from.
| A video with no captions | Pages, PDFs and e-books | Video sites it names | |
|---|---|---|---|
| WatchTranslate | Writes the original line and your language from the speech while it plays[1] | Not covered: WatchTranslate translates video only[1] | YouTube, X, Bilibili and more, plus files on your own computer[1, 2, 3] |
| Immersive Translate | Subtitles generated from the audio are part of its Pro membership[4] | Side-by-side page translation, PDFs with the layout kept, ePub books[5] | More than 60 video platforms, YouTube, X and Netflix among them[6] |
| YouTube's own captions | Only translates a caption track the video already has[7] | Not its job[7] | YouTube alone[7] |
Written by WatchTranslate, which has no tie to Immersive Translate; the name belongs to its owner.
A translator for everything, or one for video
Immersive Translate is best known for translating web pages side by side, and it also handles PDFs, e-books and video subtitles. WatchTranslate does one thing: subtitles for videos you watch. Which fits depends on how much of your translating happens inside a video player.
WatchTranslate: when the video is the point
It translates captions when a video has them and listens to the speech when it has none, writing the original line and your language a few seconds behind the picture. That works on YouTube, X, Bilibili and other video sites, in a local player for files on your computer, and in the Android and iPhone apps. You pay per minute in points after 20 free minutes, and a video someone already translated into your language is usually free.
Immersive Translate: when you read more than you watch
If most of what you translate is articles, PDFs and pages, a general translator that also does video may be all you need. Its video page names more than 60 platforms; for videos without captions, its own FAQ says the AI subtitles generated from the audio are part of the Pro membership.
Using both
They are separate extensions. Keep Immersive Translate for pages and turn it off on video tabs where WatchTranslate draws subtitles, so you don't get two sets on the same player.
