Bilibili Video Translator watch Bilibili in your language — no Chinese required.

DubTab is a Bilibili translate extension that works while you watch: an AI voice dubs the video in your language, with translated subtitles on screen. Variety clips, fan cuts, courses, donghua, live rooms — anything on bilibili.com, in Chrome, whether the video has subtitles or not.

Free 15-minute trial · No credit card · Works on videos with no subtitles at all

Watch it dub a live Chinese Bilibili stream into English — as it happens.

The site is in Chinese. The videos are in Chinese. The subtitles, when there are any, are in Chinese.

Watching Bilibili without DubTab

bilibili.com has no English interface, and most videos come with no subtitle track at all — when one exists, it's usually Chinese captions the uploader added for Chinese viewers.

Bilibili's own AI subtitles show up on a share of popular videos, in Chinese and sometimes English — text only, and not on the video you happened to open.

Live rooms have nothing: no captions, no transcript, no translation. Either you understand the streamer or you don't.

With DubTab

An AI voice dubs the video in your language while it plays — on a two-hour course, that's the difference between following along and giving up.

Bilingual subtitles show the original Chinese and your language together — for fan cuts and variety clips where you'd rather keep the person's real voice.

Live rooms too, a few seconds behind — and any video, with or without captions, because DubTab listens to the audio itself.

Translate a Bilibili video in 3 clicks

1. Add DubTab to Chrome

One click from the Chrome Web Store — the free trial is included.

2. Open the video on bilibili.com

A video page, a multi-part course, a live room on live.bilibili.com — open it in Chrome the way you normally would.

3. Turn on dub & subtitles

Pick your language once. The AI voice and translated subtitles start within seconds — or leave the dub off and keep just the subtitles.

Built for a site that wasn't built for you

Real-time AI dubbing

The voice speaks while the video plays — not a file you upload and wait for, not a subtitle file someone has to make first.

No subtitles needed

Most Bilibili videos have no subtitle track. DubTab doesn't need one — it transcribes the audio itself, so any video translates.

Bilingual subtitles

Chinese and your language on screen together — keep the original voice on fan content, or check a phrase while you learn Chinese.

Stays in sync automatically

Auto catch-up keeps the dub aligned with the video, so the voice never drifts behind the speaker — on a live room or a three-hour lecture.

Multi-part courses welcome

Bilibili courses often run as one video split into dozens of parts. DubTab keeps going as you move through them, and pauses itself when the audio goes quiet.

Live rooms too

live.bilibili.com dubs in real time, a few seconds behind the streamer — the one place on Bilibili with no captions of any kind.

What people watch on Bilibili with DubTab

Most of Bilibili never leaves Chinese — the fan edits, the courses, the live rooms. These are the ones people open DubTab for.

Chinese stars, variety shows & fan cuts

Interview clips, variety-show moments, stage cams, fan edits of the actor or singer you follow — most of it uploaded by fans, none of it subtitled in your language. Bilingual subtitles let you follow every line and keep their real voice.

Courses & tutorials taught in Chinese

Animation and drawing courses, software walkthroughs, university lectures — hours long, split into parts, taught in Chinese. Hear the teacher dubbed in your language and keep your eyes on the canvas.

Donghua & original animation

Chinese animation lands on Bilibili first — often long before any subtitled release elsewhere. When an episode plays where you are, DubTab translates it the moment it drops, no waiting for a fansub.

Live rooms

VTubers, gaming, chatting, event streams on live.bilibili.com — live rooms come with no captions at all. DubTab dubs the streamer a few seconds behind, with live subtitles in your language.

Learning Chinese

Native-speed content with bilingual subtitles: hear the line, see the characters, see the translation. Turn the dub off and Bilibili becomes a listening course that never runs out.

Tech, AI & gaming from China

Chinese creators break down new models, hardware and games in depth — often the fastest take on anything made in China, and almost never in English. Watch the breakdown instead of a translated summary of it.

Doesn't Bilibili translate videos now?

It's started to. Bilibili adds AI subtitles to some popular videos, and in 2025 it began AI-dubbing videos for its international app. On bilibili.com in the browser, though, what you get is still mostly Chinese — and that's where DubTab works: any video, any live room, your language, in real time.

The English version is the app. The browser is still Chinese.

Bilibili relaunched its international app in 2026 with AI dubbing, and says an English website is coming. Until it does — and for everything beyond Chinese-to-English — bilibili.com in Chrome is a Chinese site with Chinese videos. DubTab works there today, on your side of the screen, in any of 60+ languages.

Fan content wants subtitles. Courses want a voice.

For a variety clip or a stage cam, you want the person's real voice: turn on bilingual subtitles and leave the dub off. For a three-hour drawing course, you want to hear the teacher and watch the canvas: turn the dub on, and the original voice stays underneath at whatever volume you like. Same extension, your call for every video.

Multi-part videos, marathon live rooms.

Bilibili courses are often one video split into dozens of parts, and live rooms run for hours. DubTab follows the tab as you move from part to part, pauses itself when the audio goes quiet, and counts only the time it's actually listening.

Frequently asked questions

Some videos do — either the uploader added them, or Bilibili's AI subtitles generated an English track for a popular video. Most videos have no subtitles at all, or Chinese-only captions. DubTab doesn't depend on any of that: it listens to the audio and gives you subtitles and a dub in your language on every video.

The next Bilibili video you open — in your language.

Install once — the dub starts the moment the video does, on any bilibili.com page.
