HearSub is a browser extension that adds real-time subtitle translation and AI dubbing to YouTube. Instead of uploading and reprocessing a whole video, it reads the captions the player already has, translates only the lines around the playhead, and prepares target-language audio ahead of playback. That keeps translated subtitles, bilingual captions and AI voice-over in sync while you watch foreign-language courses, interviews, podcasts and tutorials in your own language.

HearSub is a browser extension that adds real-time subtitle translation and AI dubbing to YouTube. Instead of uploading and reprocessing a whole video, it reads the captions the player already has, translates only the lines around the playhead, and prepares target-language audio ahead of playback. That keeps translated subtitles, bilingual captions and AI voice-over in sync while you watch foreign-language courses, interviews, podcasts and tutorials in your own language.
HearSub translates only the lines near the current playhead and updates them as the video plays, so you do not wait for a whole file to finish processing.
Show both the original and translated text together to follow the meaning and pick up the source language as you watch.
HearSub prepares target-language audio ahead of playback so the AI voice tracks the speaker instead of lagging behind.
Translation and dubbing are tied to playback position, so switching between languages stays aligned with what is on screen.
