DubTab is a browser extension for real-time voice translation and AI dubbing in any browser tab. Watch videos, live streams, meetings, and online classes in other languages with natural dubbed audio and optional bilingual captions. It’s designed for people who want to follow global content more naturally — whether that’s live news on YouTube, cross-language meetings, or online learning — without relying only on subtitles.

SonicCaption is a Chrome/Edge extension that overlays ultra-low-latency live captions and instant translation on any video or meeting—YouTube, Zoom, Google Meet, courses, livestreams, and more. Show bilingual subtitles or translation-only, and customize styles to match how you learn and watch.
