YouTube Dubbing Extension watch any video in your language.
DubTab translates YouTube videos while you watch — an AI voice dubs the speaker in your language and translated captions follow on screen. No uploads, no waiting, no captions required.
Free 15-minute trial · No credit card · Works on videos without captions
Watch it dub a real YouTube video — live.
Stop reading videos. Start watching them.
Auto-translated captions only exist when the video has captions — and their quality is whatever the source captions were.
The dub track skipped your language, or the video never got one at all — and you can't request it.
Eyes locked on the caption line for an hour: you're reading the video, not watching it.
An AI voice dubs the speaker in your language while the video plays — look away, take notes, just listen.
No captions needed — DubTab listens to the audio itself, so any video translates.
Show original and translated captions together — learn the language, or check the translation as you go.
Translate a YouTube video in 3 clicks
1. Add DubTab to Chrome
One click from the Chrome Web Store — the free trial is included.
2. Open any YouTube video
A tutorial, a lecture, a podcast, a Short or a live stream — play it as usual.
3. Turn on dub & captions
Pick your language once. The AI voice and translated captions start within seconds.
Built for watching, not just translating
Real-time AI dubbing
The voice speaks while the video plays — not a file you upload and wait for.
No captions needed
DubTab listens to the audio itself — videos with no CC translate just the same.
Bilingual captions
Original and translation on screen together — for learning a language or checking the translation.
Stays in sync automatically
Auto catch-up keeps the dub aligned with the video, so the voice never lags behind the speaker.
Long videos welcome
Full lectures, podcasts and films — DubTab keeps going where auto-dubbing rules videos out.
Live streams too
Live streams dub in real time right in the browser — no waiting for the replay.
What people watch with DubTab
The knowledge on YouTube isn't in one language — your feed doesn't have to be either.
Crypto, trading & finance
Bitcoin commentary, earnings breakdowns and macro analysis from creators in any language — understand the full reasoning, not a caption summary of it.
Tech & AI
Model releases, coding walkthroughs, conference talks and AI news — the best explanation is often not in your language, and now that's fine.
VTuber & idol videos
Uploaded streams, archives and clips from virtual idols — real-time translated captions that keep their real voice, with a dub there if you ever want it.
Lectures & full courses
University lectures and multi-hour courses stay watchable when you're listening — not decoding captions for two hours straight.
Podcasts & interviews
Podcasts are made for listening in the background — which reading captions never was. Put on a dubbed interview and keep your hands free.
Tutorials & how-to
The exact repair, setup or fix you need exists on YouTube — just not in your language. Watch it dubbed instead of guessing from gestures.
Doesn't YouTube already translate videos?
Sometimes — and when it does, use it. YouTube can auto-translate captions on videos that have them, and auto-dubs some eligible videos. DubTab covers everything else: videos with no captions, languages the dub skipped, live streams, and every time you'd rather listen than read.
| The video you're watching | What YouTube gives you | DubTab |
|---|---|---|
| Has an official dub in your language | Use it — it's built into the player | ✓ Adds bilingual captions on top, if you want them |
| Has captions, but no dub for you | Auto-translated captions — text only, quality follows the source | ✓ Real-time dub + translated captions |
| No captions at all | Auto-translate unavailable | ✓ Works anyway — it listens to the audio |
| Live stream | Auto captions in English only, on some streams | ✓ Real-time dub + captions, your language |
Auto-dubbing is the creator's feature — not yours.
YouTube generates dubs when an eligible video is uploaded, and the creator can turn them off. Very long videos, music-heavy audio, fast speech and many languages fall outside it — and as a viewer you can't request a dub. DubTab works from your side of the screen: the video you're watching right now, in the language you pick.
Shorts translate too.
Cooking hacks, news clips, language snippets — Shorts play with the same real-time dub and captions. Keep scrolling; the translation follows.
Two languages on screen at once.
Turn on bilingual captions to see the original line and its translation together — the way language learners shadow a video, or the quickest way to check what the translation actually said.

Install once — the dub starts the moment the speaker starts talking.
