Udemy Video Translator hear any course in your language.
DubTab is a Udemy translate extension that works in real time: it translates the lecture and speaks it in your language with an AI voice, while translated captions follow on screen. Use either, or both — on any course, including Udemy Business.
Free 15-minute trial · No credit card · Works on udemy.com and Udemy Business
Watch it translate a real Udemy lecture — live.
Lectures in your language — not just the caption bar.
The course lists [Auto] captions in 30 languages — but the instructor is typing code on screen, and every second you spend on the caption bar is a second you're not watching the editor.
[Auto] captions are machine text: a misheard variable name gets translated as confidently as a correct one, and you can't hear the original well enough to catch it.
Your course is smaller, newer, or taught in another language — so the CC menu holds the original language, or nothing at all.
Listen in your language and keep your eyes on the code, the slides and the demo — translated captions are one click away when you want to read along.
DubTab listens to the audio itself, so it doesn't depend on Udemy's captions being there, or being right.
Auto catch-up keeps the dub in sync with the video, so the voice never drifts behind the instructor.
Translate Udemy with a Chrome extension in 3 clicks
1. Add DubTab to Chrome
One click from the Chrome Web Store — the free trial is included.
2. Open any Udemy lecture
Play the video as usual — a course you bought, your company's Udemy Business portal, or the free preview lectures on a course page.
3. Turn on dub & captions
Pick your language once. The AI voice and translated captions start within seconds.
Built for studying, not just translating
Real-time AI dubbing
The voice speaks while the video plays — not a file you upload and wait for.
Bilingual captions
Translated captions alongside the original, or your language alone. Read along with the dub, or use captions on their own — both follow the lecture live.
Stays in sync automatically
Auto catch-up keeps the dub aligned with the video, so the voice never lags behind the instructor.
Works from the audio, not the captions
DubTab listens to the lecture itself, so courses with no captions, wrong captions, or captions only in the original language work the same — and a course taught in Spanish, Hindi or Portuguese is detected automatically.
Udemy Business and previews too
Anything that plays in a Udemy tab gets dubbed the same way — courses you bought, your company's Udemy Business portal, and the free preview lectures on a course page.
Windows desktop app included
Dub anything beyond the browser — local videos, meetings, any app's audio.
What people learn on Udemy with DubTab
Udemy's biggest courses are screen recordings: someone typing, clicking and explaining at the same time. That's exactly where a voice beats a caption bar.
IT and cloud certifications
Networking, cloud, data-platform and CRM exam prep — courses where the instructor works through consoles and configs while explaining. Follow the explanation in your language without looking away from the screen.
Cybersecurity and ethical hacking
Bug bounty, penetration testing and security fundamentals — courses full of tool names and terminal output, where one mistranslated caption costs you the thread. The dub carries the terminology in your language.
AI tools, agents and automation
AI-assisted coding, agent frameworks, no-code automation — the fastest-moving category on Udemy, where new courses arrive faster than their captions do.
Programming bootcamps
JavaScript, Java, Python, mobile and backend frameworks — hours of live coding. Hear the explanation while you watch the code being written, instead of reading it at the bottom of the screen.
PMP, business analysis and finance
Certification prep and business courses built on frameworks and vocabulary — keep up with the terms in your language while you take notes.
Design, 3D and game development
Photo editing, illustration, 3D modeling and game engines — courses where the instructor's cursor is the lesson. A voice lets you watch it; captions make you choose.
Doesn't Udemy translate courses itself?
It captions them. Popular English courses get automatic captions in 20–30 languages, labelled [Auto]; smaller courses often have only the original language, or nothing. Nothing on Udemy speaks your language — there is no dubbing — and that's where DubTab comes in.
| What you're watching | What Udemy gives you | DubTab |
|---|---|---|
| A course whose instructor uploaded subtitles in your language | Human-made subtitles — use them | ✓ Adds the voice; keep their subtitles, or DubTab's bilingual captions |
| A popular English course | [Auto] captions in 20–30 languages — machine text, the audio stays English | ✓ Real-time dub in your language, plus captions |
| A smaller or newer course, or a language missing from its [Auto] list | Captions in the course's own language, or none | ✓ Real-time dub + captions, 60+ languages |
| A course taught in Spanish, Portuguese, Hindi or another language | Captions in that language at most | ✓ Detects the spoken language, dubs it into yours — English included |
Udemy captions the text. Nobody speaks your language.
Udemy's answer to language is the CC menu: auto-generated captions, and on popular English courses, [Auto] translations of them. There is no dubbed audio track on Udemy — asked about AI dubbing in September 2025, Udemy said the idea had been shared with its team. DubTab is the missing half: it translates the instructor's voice itself, live, on the same tab, in 60+ languages.
[Auto] captions come with the course, not with your account.
Which languages a course has is decided course by course: a bootcamp with a million students may list 30, a course with a few thousand may have only its original language, and courses need 20 enrollments before they get auto-captions at all. DubTab doesn't work from the list — it listens to the audio, so every course gets the same 60+ languages.
Udemy is screen recordings. Captions make you look away.
Most Udemy courses are someone typing, clicking and explaining at once. Reading the caption bar means missing the line of code, the menu, the brush stroke. With the dub carrying the explanation, you watch what the instructor is doing — and translated captions stay one click away for the moments you'd rather read.
