SubSync — Realtime Subtitle & Translate

About

SubSync turns the audio of any tab into live subtitles — and translates them into 60+ languages on the fly.

No more relying on platform captions. SubSync transcribes the audio your browser is playing in real time, so it works on sites that don't ship subtitles: Netflix originals in foreign languages, YouTube videos without CC, Zoom meetings, Google Meet calls, podcasts, news streams, and more.
