Are Bilibili's own subtitles enough?
Bilibili's subtitle menu is designed for Chinese readers. Here is how the common cases look for an English speaker.
| The video you're watching | What the Bilibili player offers | With WatchTranslate |
|---|---|---|
| Uploader or AI subtitles exist | Signed out, the subtitle menu shows only 登录可享; what language a track is in depends on the video | Signed out: English from the audio. Signed in: the uploader's track can be translated |
| No subtitle track at all | The Chinese soundtrack only | Transcribes the Mandarin and translates it as the video plays |
| Hours-long replays and multi-part series | Same as above, part by part | Each part gets its own subtitles, and a whole part can be prepared in advance |
The Bilibili column reflects the bilibili.com web player's subtitle menu on November 8, 2026, signed out. Check Bilibili's current page.

How WatchTranslate makes the subtitles
Where does the English come from on a video with no subtitles?
WatchTranslate works through the playing video in short stretches: it recognizes the Mandarin in each stretch, then translates it into English. The current stretch and the next one come first, so subtitles keep pace with playback.
Why do names and terms stay consistent?
Each sentence is translated with the lines around it in view, so a plant name or a game term keeps the same English wording through the video.
Why do some videos show subtitles straight away?
Results are kept per video and target language. If someone already translated the same Bilibili video into English, those subtitles are reused.
Get the most out of it
Start with one clear narrator
Explainers and vlogs with one main voice give the cleanest English lines.
Keep the characters for study
When you are practising Mandarin, leave the default bilingual view on and export the SRT afterwards.
Long replays: prepare first
Start "Translate all subtitles in advance" before a long replay, then skip around freely.
Bilibili video translator questions
How do I get English subtitles on Bilibili?
Install WatchTranslate in Chrome or Edge, open the video on bilibili.com, click WT on the player, set Target language to English and switch it on. English lines appear as the video plays.
How do I watch Bilibili in English?
The site menus stay in Chinese, but what people say shows up in English on the player. The WatchTranslate panel has English labels.
Is there a Bilibili video translator that works right on the page?
Yes. WatchTranslate runs on top of the bilibili.com player, so there are no video files to download or upload.
Is there a Bilibili translate extension for Chrome?
Yes, WatchTranslate is a Chrome and Edge extension. After installing it, a WT button appears on the Bilibili player.
Do I need a Bilibili account?
No. We tested signed out of Bilibili, using audio recognition. If you do sign in and the uploader added a subtitle track, that track can be translated too. A free WatchTranslate account holds your free minutes.
The video has no subtitles at all. Does it still work?
Yes. That is what Audio recognition is for: WatchTranslate builds subtitles from the Mandarin audio.
Is it useful for learning Mandarin?
Many learners use it that way: subtitles show the characters with the English by default, and you can export SRT or VTT to review later.
What about multi-part uploads and bangumi?
Open the part you want and click WT; subtitles follow that part. Bangumi and films you can already play on Bilibili work the same way.
Can I use it on my phone?
On Android, install the WatchTranslate app, open the Bilibili video inside the app and tap Translate.
How much is free?
New accounts get 20 free minutes, no card needed.
Is WatchTranslate part of Bilibili?
No. It is an independent extension and app that shows subtitles over the Bilibili player without changing the video.
