# EarDub Review Chrome and Edge extension that dubs YouTube, Udemy, Coursera, and Bilibili videos into 75 languages with synced AI voices, no upload ## Editor's Score: 72/100 Capability scores 19 because the context-aware translation and auto-advance on course platforms are genuinely useful differentiators, but the hard exclusion of uncaptioned video dubbing on Udemy and Coursera (the two platforms most relevant to its core audience) is a real feature gap. Ease of use scores 21 because the install-click-listen flow has almost no friction and no upload step, which is the whole point of a browser extension. Value scores 20 because the free tier requires no card and the Pro plan at $19.99/month covers unlimited personal use, which is fair for the category. Delivery scores 12 because no user review data, ratings, or independent assessments surfaced in search, the product appears to be an indie tool with no documented track record of scale, and the social media presence could not be confirmed at all, making it hard to assess how reliably the service performs or how responsive support actually is. ## Pros - Context-aware translation keeps domain terms and idioms consistent across a full video, not just sentence by sentence. - Free plan requires no credit card and gives 30 minutes of dubbing per day, enough to evaluate the quality before paying. - Auto-advance on Udemy and Coursera means a dubbed course plays through without manual intervention between lectures. ## Cons - The free plan's 30-minute daily cap resets every 24 hours with no rollover, so a single 45-minute lecture exhausts the day's quota and leaves nothing for a second video. - Speech recognition for uncaptioned videos is not supported on Udemy or Coursera, only on YouTube, X, Bilibili, and Gumroad, which is a real gap for paid course learners. - Desktop Chrome and Edge only: no mobile app, no Safari support, and no way to dub videos on a phone or tablet regardless of plan. ## Pricing Freemium. A free tier is available. - Free: $0/mo - Basic: $9.99/mo - Pro: $19.99/mo Pricing reflects what we saw at the time of review (2026-10). Confirm current pricing on the official site.

Directory: https://aitoolseekers.com This review: https://aitoolseekers.com/tools/eardub Methodology: https://aitoolseekers.com/how-verification-works ## Verdict EarDub is the right pick for students and self-learners who want to follow foreign-language video courses or tutorials without reading subtitles the whole time. The free tier's 30-minute daily cap is genuinely restrictive for anyone watching more than one lecture a day, and the tool only runs on desktop Chrome and Edge, so mobile learners are out. If you need to produce translated or dubbed video files rather than just watch them in your browser, HeyGen is the better fit. Best for: Students and self-learners consuming foreign-language video courses Not for: Mobile viewers, live-stream watchers, or anyone who needs a dubbed video file to share ## Overview EarDub is a browser extension for Chrome and Edge that dubs videos as they play, without any upload or rendering step. You open a video, click the EarDub button in the player (or press Shift+D), pick a language and voice, and the dubbed audio starts immediately. The extension reads the video's captions, merges the fragmented caption lines into full sentences, translates them with awareness of the video's title and topic, and plays a neural TTS voice synchronized to the original speaker. On paid plans it can also recognize speech in uncaptioned videos on YouTube, X, and Bilibili. The translation approach is the most distinctive technical claim: rather than translating caption fragments word-by-word, EarDub uses the full video context so that idioms and domain-specific terms stay consistent across a long video. The site gives a concrete example: in a business talk, "they'll eat your lunch" becomes "they'll take your customers" rather than a literal food reference. Bilingual subtitles and separate volume controls for the original and dubbed audio are also available. The platform coverage is specific and worth knowing before you install. YouTube, X, Bilibili, and Gumroad work on all plans including free. Udemy and Coursera work on all plans for captioned videos, but speech recognition for uncaptioned videos is not supported on those sites. The extension auto-advances to the next lecture on Udemy and Coursera. There is no mobile app; this is strictly a desktop browser tool. EarDub sits in a different category from tools like HeyGen or Descript. Those tools produce dubbed or edited video files. EarDub produces nothing you can save or share; it is purely a viewing aid. That is a real constraint for some buyers and a non-issue for others. ## Who should use it EarDub fits anyone who regularly watches foreign-language video content on a desktop browser and wants to listen rather than read. The clearest use cases are students taking Udemy or Coursera courses in a language they are still learning, developers following English-language technical tutorials, and researchers or journalists who need to get through interview footage or documentary content in another language quickly. The auto-advance feature on Udemy and Coursera is a genuine time-saver for course learners working through multi-lecture series. Anyone who needs a dubbed video file they can download, share, or publish should look elsewhere. HeyGen handles video translation and dubbing as a production output, including lip-sync on avatar videos, and is the right tool if the goal is delivering localized content to an audience rather than consuming it yourself. Mobile-first viewers will also find EarDub useless since it has no app and the extension does not run on phones or tablets. ## FAQ Q: Does EarDub work on videos without subtitles? A: Yes, but only on Basic ($9.99/month) and Pro ($19.99/month) plans, and only on YouTube, X, Bilibili, and Gumroad. Udemy and Coursera require captions on all plans. Q: Is there a free plan and what are its real limits? A: The free plan gives 30 minutes of dubbing per day with no credit card required. Minutes reset daily with no rollover, so a single lecture over 30 minutes will exhaust the day's quota. Videos without captions and study notes are not available on the free plan. Q: Does EarDub work on mobile? A: No. EarDub is a desktop browser extension for Chrome and Edge only. There is no iOS or Android app and no Safari support. Q: Does replaying a video use up my dubbing quota? A: No. Quota is counted by actual dubbed playback time, not by the number of times you open a video. Replaying the same video does not consume additional minutes. Q: What does 'unlimited' mean on the Pro plan? A: No cap on dubbing time, video length, or daily video count for normal personal viewing. Automated, commercial-scale, or shared-account use may be restricted under the terms of service. Q: Can I get a refund if I upgrade and change my mind? A: Eligible subscriptions can be refunded under conditions set out in EarDub's terms of service. You can cancel anytime under 'Manage subscription' and keep access until the end of the billing period.
