About

Hi, I’m Ethan — a solo developer building browser extensions that remove language barriers. I’m currently focused on SonicCaption: ultra-low-latency live captions + instant translation for videos and meetings across the web. I love shipping fast, sweating UX details, and learning from real user feedback. If you’re a language learner or work across languages, I’d love to hear what would make this tool truly indispensable for you.

DubTab - Real-time voice translation and AI dubbing for any page

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.
