Real-time voice translation + AI dubbing
Live subtitles, optional bilingual captions, and low-latency audio dubbing — on videos, calls, and livestreams. No files to upload. No waiting.
Works on any site with audio — YouTube, Netflix, Twitch, Zoom, and more.
How it works
1. Install DubTab
Pin DubTab in your browser bar for quick access.
2. Open Any Tab
YouTube, Netflix, Zoom, Twitch, courses... anything with audio.
3. Hit Start
Pick your languages and voices. DubTab listens and dubs instantly.
Works on any browser tab with audio or video
Including:
Built for how you actually watch
Learn without language limits
Take courses on Udemy, Coursera, or any platform — real-time subtitles and dubbing let you focus on learning, not translating.
Catch every livestream moment
YouTube Live, Twitch, or any stream — get instant translations so you never miss the action or the jokes.
Stay present in global meetings
Zoom, Google Meet, Teams — read what people say in real time without asking them to repeat.
Follow your favorite idols
K-pop lives, variety shows, fan content — understand every moment without waiting for fan subs.
Why it's different
Real-time, low-latency
Dubbing and subtitles appear in ~0.5s, good enough for live streams.
Voice options & Ducking
Choose your AI voice and control original volume ducking.
Dual subtitles
See original and translation at the same time (optional).
Universal compatibility
If the tab plays audio, DubTab can listen.
No manual uploads
No files, no exports. DubTab translates whatever the tab is playing, as it plays.
Privacy controls
Source tab audio is processed in real time and is not saved as a recording. If you turn on Save dubbed audio, only the translated AI voice generated by DubTab is saved privately to History, where you can replay or delete it.

Why I built DubTab
Hi, I'm Ethan Hu — and I built DubTab for one simple reason: I wanted to spend less energy fighting the language, and more energy understanding the content.
DubTab provides real-time translation in your browser with live subtitles and optional AI voice dubbing, so you can keep up with videos, courses, and meetings without constant pausing or rewinding.
If DubTab helps you even a little, that means a lot to me. And if it doesn't, tell me what would make it better — I read every message.
