A browser extension that turns any foreign-language video into a dub in your language — line by line, in sync with the picture, with the original atmosphere kept underneath. No more staring at subtitles.

Translations run longer or shorter than the original, so a naive dub drifts further off with every sentence. We control the length and pace of each line in five stages so the dub starts and ends with the picture. The panel shows a measured sync rate, and you can hear the naive version for comparison.
We don't mute the video and read over it. By default only the voice band is ducked, so applause, ambience and most of the music stay. For music-heavy videos, switch to full mute or center-vocal removal with one click.
Scrubbing, 1.5×, the next video, mid-roll ads — it keeps up. If the dub isn't ready yet it pauses for you instead of falling behind.
Chrome, Edge or Firefox. YouTube, Bilibili and Vimeo load automatically; any other page with a video works from the toolbar button.
Any of 40 target languages — English, Spanish, Japanese, Hindi, Arabic and more. The source language is detected from the captions; no captions? It can transcribe the audio.
The dub follows the video. Translated lines appear in the panel; click any line to jump there, export an SRT, or ask for a summary.
Because it's the creator's feature, not yours. Auto-dubbing only exists when the creator turned it on, only for the language pairs YouTube supports, only on YouTube, and it can't be edited or re-voiced. HearIt runs on your side: any video with captions, any website, any of 40 languages, your choice of voice. Full comparison →
40 target languages, covering every language YouTube's own dubbing supports, plus Cantonese, Turkish, Dutch, Polish, Swedish, Hebrew, Persian, Malay, Filipino, Tamil, Bengali, Urdu, Swahili and more. Source language is detected automatically.
In beta. Streams have no captions, so audio is transcribed first and the dub arrives about 25 seconds behind the picture. One click pauses the stream for 25 seconds so the two line up.

Neural voices from Azure, MiniMax and others, with a male and a female voice for every language. Speaker gender is detected so multi-person videos get different voices.
Captions are sent for translation and the resulting audio is generated on our servers; nothing else leaves the page. Transcription (for videos without captions) sends short audio chunks. See the privacy policy.
Plans are billed by dubbing time, not by number of videos. Start free, upgrade only if you keep using it. See plans in USD
