Subtitles, dubbing and video translation in one browser-based editor
Automatically transcribe uploaded video and produce captions in more than 100 languages, including bilingual subtitle sets for language-learning and international publishing.
Proofread and correct auto-generated captions directly in the web editor, fixing timing, wording and speaker labels before export.
Customise fonts, colours, sizes and positioning so captions match a channel's visual identity across vlogs, shorts and long-form uploads.
Translate the spoken content and generate a voice track in the target language, so the same video can be published to non-native audiences without re-recording.

Watch foreign-language YouTube videos in your own language, in real time
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.
