YouTube Dubbing Extension: AI Auto Dub - EarDub by chris

EarDub is a YouTube dubbing extension and AI video translator for Firefox on desktop and Android. It translates foreign-language videos with AI and dubs them into your language in real time, in sync with the speaker, so you can listen instead of reading subtitles. It works on YouTube, Udemy, Coursera, X, Bilibili and most other sites, on computers and Android phones, with nothing to upload. The free plan dubs 30 minutes a day of videos with captions; Basic and Pro also dub videos without captions.

EarDub's AI translation follows the context: it uses the video's title, topic and scene to translate whole sentences, so the dub sounds accurate and natural, not like stiff machine translation. One click, and you hear the dub in your language within seconds. Beyond dubbing, EarDub's AI also turns videos into chapter summaries and study notes, so you catch the key points faster and can review them anytime.

• ★ Built for online courses and learning: on Udemy and Coursera the next lecture is dubbed automatically, and names and technical terms stay consistent throughout
• ★ Real-time sync: the dub starts the moment the speaker does, and keeps up when you pause, skip or rewind
• ★ Dubs videos without captions (Basic and Pro) on YouTube and most other sites
• ★ 75 languages and 300+ AI voices, male and female, with accents such as Indian or Irish English, Mexican or Argentine Spanish, Gulf or Levantine Arabic
• ★ Context-aware AI translation: in a business talk, "they'll eat your lunch" becomes "they'll take your customers", not a line about food

New: AI chapter summaries and study notes (for videos with captions)
- ★ AI chapter summary: an overview of the whole video plus the key points of each chapter; click a chapter and the video and the dub jump there together, so even hours-long videos are easy to find your way around
- ★ AI study notes: AI skips the chatter and ads and writes study notes with the key conclusions, steps, numbers and terms explained, ready to export to PDF or Word (Pro; Basic can try it on 3 videos a month)

FAQ
Does it work on my phone?
Yes. On Android, install EarDub in Firefox for Android (version 142 or newer); it works just like on a computer. iPhone and iPad aren't supported yet.

What can't it dub?
Live streams aren't supported yet.

How accurate is the AI translation?
EarDub translates whole sentences in context, so most videos come out accurate and natural; results also depend on the audio quality and how hard the topic is. To check a line, turn on bilingual subtitles and compare it with the original.

Privacy
EarDub runs only when you click it: on YouTube by default, and on other sites after you allow them. Subtitles and the video title (or short pieces of audio when there are no subtitles) go to EarDub's servers for translation and speech. Audio isn't stored.
