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.
