YouTube Dubbing Extension: Hear Any Video in Your Language - EarDub · eardub.com

Changed the default language from Chinese to "follow browser", and in one month it went from 135 to 1,000: the pivot of EarDub, a YouTube dubbing plugin

What it is A browser extension. When you watch YouTube, Udemy, or Coursera lectures, it translates the video in real time and dubs it with an AI voice in your language, synced to the speaker.

Why it blew up It was originally built for Chinese users with Chinese as the default. After it switched to following the browser language in Oct 8, expanded dubbing voices from 18 to 75 languages, and added course sites and Edge, non-Chinese users could finally use it. On top of that, the store title and official SEO pages were all built around the term "YouTube dubbing extension."

CHow you could follow it Stop building a generic YouTube dubbing extension. Copy its two moves: a tool that serves only one language, expanded globally in the same order; or pick a narrow learning scenario and language pair for dubbing, with subtitle reading free and speech recognition paid, and use scenario pages and comparison pages to capture search.

Grade C: the demand is real, but the category already has dozens of similar tools, and the ones ahead have 200k, 60k, and 30k users. EarDub itself is only in the tail. Its growth came from filling in globalization, which a follower can't capture, and YouTube or the browser could build this in as a native feature at any time. Hardly anyone knows about it yet

EarDub is a browser extension that dubs YouTube and course videos into your language in real time. It sat in the Chrome store for over three months with only fifty or sixty users. In early October the author changed one default setting, added 75 languages plus Udemy and Coursera, and in one month it reached 1,000. This piece covers what changed, where the users came from, and how it makes money. There's also a more important point: in the same period, several other extensions doing the same thing already had 30k to 60k users.

A one-line changelog

Around 2026 Oct 8, Shenzhen indie developer Zhang Qianfeng (his name on the website is Chris Cornell) shipped v0.1.20 of EarDub. This changelog entry is understated:

the dub language now defaults to your browser language (English if it isn't supported) instead of Chinese

The same update also had a line about the quota-exhausted prompt: it "now appears in your language instead of Chinese".

So until then, an American or Indian user installs EarDub, opens YouTube, and hears Chinese dubbing with Chinese prompts. The extension Jun 16 launched with an English title and store description, but the product itself was built for Chinese users. Here's its user count over these three-plus months (tracked by extops.dev): Aug 31 57 users, Sep 15 65 users.

On the day v0.1.20 shipped, the user count was 135. After that:

DateChrome usersWhat happened those days
10-08135v0.1.20: default dubbing language switched to follow browser, welcome page added
October, mid—v0.1.21 added Udemy and Coursera; v0.1.24 expanded dubbing languages from 18 to 75; launched on the Edge store
10-16334v0.1.32: Udemy courses without subtitles can now be dubbed too
10-19482
10-24793+179 in a single day, the biggest jump of the month
10-29992
11-061,000Once the store passes 1,000, the count is rounded, so you can't tell whether it kept growing

Sources: extops.dev user curve, the EarDub official changelog, Chrome Web Store (11-06). The Firefox version launched 22 October, with 25 daily actives; Edge installs are 148, and the two together are less than a fifth of Chrome.

So EarDub's "traction" is basically a Chinese-only tool finally working for non-Chinese users. This is catching up, not a new invention. But it's catching up fast: from June to November it shipped 40 versions, and in October alone it went from 0.1.20 to 0.1.39.

What it does

Once installed, a dubbing button appears in the bottom-right corner of the YouTube player. Click it, and after about 10 seconds an AI voice starts reading the video aloud in the language you picked, with the original audio ducked to 20% volume underneath and bilingual subtitles. Its pitch is "for viewers, not creators": no uploading, no exporting, and you can dub other people's videos.

Compared with typical YouTube dubbing extensions, it has three extra things:

  • Translates whole sentences. It first stitches fragmented subtitles into complete sentences, then translates them with the video title, context, a per-video glossary of names and terms, and a style guide for each language. The store listing's example: "they'll eat your lunch" becomes "they'll take your customers," not the literal "they'll eat your lunch."
  • Prepares ahead, speaks in sync with the speaker. It reads subtitles or audio the player has already buffered, generates sentences in advance, and if the translation runs long it speeds up to at most 1.45x instead of cutting off.
  • Not just YouTube. It can keep dubbing the next lesson on Udemy and Coursera, and also supports X, Bilibili, Gumroad, plus subtitled videos on sites like TED and Wistia. On Android it works in Vivaldi and Firefox.

The voice names are Jenny, Guy, Nanami, Xiaoxiao, Yunyang. They look like Microsoft Azure neural voices (inferred), so the voices themselves aren't a moat.

People who install it actually use it. In Nov 4 it published a blog post on its own site about "dubbing latency" and, as a side note, disclosed telemetry for one week from Oct 28 to Nov 4: desktop YouTube 1,889 times, Android 222 times, Udemy 293 times, Coursera 99 times, other sites 223 times, roughly 2,700 in total, about 390 a day on average. For a plugin with 1,000 users that's not small, and online courses (Udemy + Coursera) account for about 15%.

The store shows 5 ratings in total, averaging 4.8 stars (11-06). One review from a Vietnamese user in Oct 23 reads: "correct, fast and no make lagging." Another from Oct 29 is signed "chris," same as the author's English name (can't tell whether it's really him).

Where the money comes from

The free tier, after login, gives 30 minutes a day and up to 3 videos, and only for videos with subtitles (auto-generated subtitles count). Videos without subtitles require speech recognition, which is expensive, so that's only in the paid tier:

TierPricingQuota
Free030 minutes a day, up to 3 videos, subtitles required
Basic$9.99/month or $83/year60 hours a month, works on videos without subtitles
Pro$19.99/month or $155/yearUnlimited length

Source: eardub.com/pricing. Payments via Stripe, WeChat Pay goes through a separate channel. The tiering by cost is clear: cheap work (reading existing subtitles) is free, expensive work (speech recognition) is paid. Revenue isn't public, and the number of paying users isn't visible from outside.

Where users come from

  1. Globalization, the key part, and it's documented. Default language, 75 dubbing languages (recently added Bengali, Tamil, Urdu, Thai, Swahili and others), and Arabic / Turkish / Russian / Vietnamese interfaces. The user curve bends right from these updates.
  2. Store title stuffed with search terms. The current title is "YouTube Dubbing Extension: Hear Any Video in Your Language - EarDub," with the brand at the end. Two old URLs still show up in search engines, eardub-ai-voice-translato and eardub-youtube-dubbing-vo, which suggests the title has been changed at least twice, each time moving closer to the phrase "YouTube Dubbing Extension." The renaming dates can't be found, and how much traffic it brought can't be directly confirmed.
  3. SEO pages on the website. The site has 27 English pages, each with 11 language versions: udemy-translator, coursera-translator, bilibili-translator, english-video-to-hindi-translation, and a page called turn-off-youtube-auto-dubbing, aimed at people annoyed by YouTube's default auto-dubbing who want to turn it off. There's also a set of "EarDub vs AutoDub / DubTab / LingTube / Immersive Translate" comparison posts and a piece on "8 best YouTube dubbing extensions." Most of these were written between Oct 14 and Nov 4. Searching "best youtube dubbing extension 2026" on Brave, it ranks #7; searching "youtube dubbing extension" it doesn't appear in the top ten. The path has just been paved and hasn't yet brought in much.
  4. Store "related extensions" slot. On the detail page of AutoDub, which has 30k users, EarDub is the first related recommendation, so the big extension passes it a bit of traffic.
  5. Directory backlinks, almost no traffic. Submitted in bulk to Fazier (0 upvotes), Toolify, dang.ai, twelve.tools and others.
  6. Social and media: none. Nobody mentions it on X, searching "eardub" on TikTok turns up earphones, and there are no Reddit threads, Product Hunt launch, or press coverage. No sign of paid acquisition either.

Who it's competing with: a crowded road

There are dozens of Chrome Web Store extensions with "dub" in the name or description, and 2026 alone has over a dozen new ones. Numbers as of early November:

ProductLaunchedScalevs. EarDub
YouTube Dubbing – Translate & Dub2023-06200k users, 3.5 ratingThe veteran leader, ranks first for the category keyword on Google; low ratings

Immersive Translate / Language Reactor2018–20213M / 2MMakes bilingual subtitles, you read them yourself

livdub and AutoDub are newer extensions that gained little traction this year, with features much like EarDub's but far fewer users. In this category, distribution matters more than features in deciding scale, and EarDub's distribution has only just started. It's a tail player on this road right now.

If it were you

C. Worth learning from, not worth chasing. The demand for "watch videos dubbed in my language" is real, but dozens of extensions already do it, and several have 200k, 60k and 30k users ahead; EarDub itself reached 1,000 in a month by turning a product built only for Chinese users into one anyone can use, an opportunity that belongs only to it. And YouTube is rolling out auto-dubbing itself, while browsers (Yandex already has it) and Google could build this into Chrome at any time.

Who it fits: developers who already have a video or learning tool serving one language community and want to expand outward. EarDub's "going global" playbook can be copied as is. Or anyone with a channel into a niche learning audience (programming, trading, medical courses, a minority-language exam).

Who it doesn't fit: anyone who wants to build another "general YouTube dubbing extension" and grow through store search. The dozens in the table are your competitors, and the smallest one ahead of you is still dozens of times bigger. Also anyone without distribution who hopes to win on translation quality alone, since users can't tell the difference between good and slightly better translation and will install whichever they see first.

How to do it:

  • If you already have a tool that serves one language, follow EarDub's order: default language follows the browser → multilingual interface → expand all supported languages at once → then Edge and Firefox. These steps are cheap, and each one can correspond to a stretch of user growth.
  • If you're building something new, don't build "YouTube dubbing." Build a narrow niche: one category of paid course platform, one language pair (English video → Hindi, → Indonesian), or one type of instructional video where viewers have to watch the screen. Price it the way EarDub does: free for reading existing subtitles, paid for speech recognition.

How to get users: start the store title with the category keyword and put the brand last; build a page on the site for each scenario and each competitor ("X translator," "EarDub vs X"), plus a page that catches reverse demand from platforms (EarDub's "how to turn off YouTube auto-dubbing"); write up your own usage data as a blog, which is both content and social proof. These are slow tactics, and after three weeks EarDub still hasn't climbed the rankings. If you want speed, you need another channel, such as people who run learning-focused short-video accounts.

When is the window: there's no clear window. The threat comes from platforms: if YouTube expands auto-dubbing to more languages and lets viewers turn it on themselves, or Chrome builds in video translation, the category shrinks together.

What would show this read is wrong: (1) EarDub climbs past the 10k-user tier on the Chrome Web Store without any new distribution moves, which would mean the course-site plus SEO path works better than expected and vertical dubbing extensions are worth pursuing seriously; (2) a single-site course extension (like the Udemy version) grows to tens of thousands of users, showing the vertical audience is big enough to follow; (3) YouTube launches a viewer-side multilingual auto-dub you can toggle anytime, and the whole category ends.

Why EarDub (YouTube Dubbing Extension: Hear Any Video in Your Language) is gaining traction

Channel: Chrome extension (Edge and Firefox versions also available) · ID jmlcanhchdeaepjfgdefjmbfmlkfhpeh · Research date 2026-11-06

One line

EarDub is a browser extension by Shenzhen indie dev Zhang Qianfeng (goes by Chris Cornell / chris zhang externally) that dubs YouTube and online course videos into your language with real-time AI voice. Its "breakout" is very small: 8–September it sat at 50 to 60 users, then after going global around Oct 8 it grew to about 1,000 a month. The rise wasn't from a viral moment. It was a product pivot: the UI and default language switched from Chinese to follow the browser, dubbing languages expanded from 18 to 75, Udemy and Coursera were added, it launched on the Edge store, and the Chrome store title was stuffed with keywords while the website got a batch of SEO pages. In a crowded category (there are old extensions with hundreds of thousands of users, and ones launched 2026 years ago that already have 3–60k users), it carved out a niche with "courses + beyond YouTube + translation by sentence meaning," but it is still a tail player in the category.

  • Source: extops.dev single page (https://extops.dev/extensions/jmlcanhchdeaepjfgdefjmbfmlkfhpeh, 30-day +886,90 day +943); our chromestore library item_snap, 11-04 and 11-06 both show 1,000 users and 4 ratings, average score 4.75.
  • Ratings: the first one came in 10-25, and by 11-01 there were 4 in total (5, 5, 4, 5). Volume is too small to tell whether it is nudging people toward good reviews.
  • Other stores: listed on Firefox 10-22, with 25 DAU, 53 weekly downloads and no ratings (AMO API); Edge has 148 installs and no ratings (Edge store API). Together the two are under a fifth of Chrome.
  • Real usage: It publicly posted telemetry on its website blog (2026-11-04, www.eardub.com/blog/real-time-ai-dubbing-delay) covering one week from 10-28 to 11-04: desktop YouTube dubbing 1,889 times, Android 222 times, Udemy 293 times, Coursera 99 times, other sites 223 times, about 2,700 in total, averaging around 390 a day. For an extension with 1,000 users, that suggests people who install it are actually using it, and online courses (Udemy + Coursera) account for about 15%.

The store lists in-app purchases. Revenue is not public, and the number of paying users is unknown.

2. Competitors: this niche is already crowded

Our chromestore library has dozens of extensions with "dub" in the name or description, with a large batch launched in 2026.

ProductWhereLaunchedScaleHow EarDub differs
YouTube Dubbing – Translate & Dub(youtube-dubbing.com)Chrome2023-06200k users, 778 ratings, 3.5 starsThe veteran leader, ranks first on Google for "youtube dubbing extension"; low rating. EarDub's selling points are whole-sentence translation with context, and support for course sites

Yandex browser's video translation, various AI earphonesOther——One is built into the browser, the other is hardware; different routes

Bottom line: EarDub is neither the first nor by far the biggest. livdub, listed around the same time, already has 60k, and AutoDub and Tofu are both at 30k. It sits near the bottom of this category.

3. Growth tactics: where the users came from

  1. Shifting the product from "for Chinese users" to "for global users" (confirmed, the most critical factor). The changelog is clear: before October, the dubbing language defaulted to Chinese, and the quota messages were in Chinese too ("EarDub's messages now appear in your language instead of Chinese"). v0.1.20 (extops records the release on 10-08) switched to following the browser language; v0.1.24 expanded dubbing languages from 18 to 75, adding Hindi, Tamil, Bengali and others; the UI also has versions in Arabic, Turkish, Russian, Vietnamese and more. The user curve turns up starting right at 10-08 135. Before that it was stuck at 50 to 60 users, essentially a small tool for Chinese users.
  2. Store search / title keywords (highly likely, not directly confirmed). The current store title is "YouTube Dubbing Extension: Hear Any Video in Your Language - EarDub", with the brand name at the end and the front a whole phrase of search terms. Search engines still index a few old slugs: eardub-ai-voice-translato and eardub-youtube-dubbing-vo; the current one is youtube-dubbing-extension, showing the title has been changed at least twice and increasingly leans toward the phrase "YouTube Dubbing Extension." The Firefox version has the same title (YouTube Dubbing Extension: AI Auto Dub - EarDub). The exact dates of the renames could not be found.
  3. Website SEO landing pages (confirmed to exist, how much traffic they bring is unverified). The website sitemap has 27 English pages, each with hreflang versions in 11 languages: udemy-translator, coursera-translator, bilibili-translator, translate-x-video, english-video-to-hindi-translation, turn-off-youtube-auto-dubbing (capturing traffic from people annoyed by YouTube's auto dubbing), youtube-dubbing-android, plus a set of "EarDub vs AutoDub / DubTab / LingTube / Immersive Translate / YouTube Dubbing" comparison articles and a "8 best YouTube dubbing extensions" list. The blog posts were mostly published from 10-14 to 11-04 (publish dates captured by Exa). However, searching "youtube dubbing extension" in Brave doesn't put it in the top ten, and searching "best youtube dubbing extension 2026" ranks it 7. This Google channel has only just been built and hasn't brought much yet.
  4. Directory backlinks (confirmed, essentially zero traffic). It is listed on Fazier (0 upvotes, a post by "product manager Chris Cornell" himself), TinyHunt (ranked 2027-01-04 at launch), Toolify, dang.ai, twelve.tools, TopAIHubs, techbasedirectory, make.rs and others. A typical bulk-submission directory approach to building backlinks.
  5. Chrome Web Store's "Related extensions" slot (some evidence). In our data, AutoDub (30k users) has EarDub at #1 in its related extensions. Detail pages of similar large extensions send it part of their traffic.
  6. Social and content: nothing found. The X corpus (x-radar, 90 days) has zero mentions; a TikTok search for eardub returns only earphones; there are no relevant Reddit posts; no media coverage, and no Product Hunt.
  7. Paid acquisition: no evidence. There are only 4 ratings, and the ratio to 1,000 users is normal, unlike fake or bought traffic.

4. Why it took off (to the 1,000 level)

  • The pivot to global was the inflection point: after 10-08 changed the default language to follow the browser, users rose from 135 to 1,000; for the three months before that it hovered around 60 (extops + changelog).
  • Found a narrower audience than "YouTube dubbing": online courses. Udemy and Coursera can automatically dub the next lesson, and Udemy courses without subtitles can be dubbed too; the website's use cases are all scenarios where your eyes must stay on the screen, like programming, trading, online courses and game tutorials. In the usage telemetry, online courses account for about 15% (website blog).
  • Keyword stuffing: the store title, the various website landing pages and the comparison articles all compete for search terms like "youtube dubbing extension", "udemy translator" and "turn off youtube auto dubbing".
  • YouTube's auto dubbing created demand and also annoyed many people: after YouTube rolled out auto dubbing over 2024–2026, searches for "hear it in my native language" and "I don't want default dubbing" both increased, and EarDub wrote pages for both (turn-off-youtube-auto-dubbing, youtube-auto-dubbing-not-available).
  • Fast iteration: from June to November it shipped 40 versions (0.1.4 → 0.1.40), and in October alone there were 0.1.20 to 0.1.39.

5. Differentiation

  • Translation follows sentence meaning: it first stitches subtitle fragments into complete sentences, then translates with the title, context, a per-video glossary and per-language style guides (changelog). An example from the store description: "they'll eat your lunch" is translated as "they'll take your clients."
  • More than YouTube: Udemy, Coursera, Bilibili, X, Gumroad, and TED / Wistia can all be dubbed, including courses behind login or a paywall; it also works on Vivaldi on Android.
  • Dubbing aligned with the picture: it uses subtitles or audio the player has already buffered, preparing sentences in advance so it can speak in sync with the speaker; overly long sentences are sped up to at most 1.45x.
  • Tiers split by real cost: the free plan only dubs videos with subtitles, and speech recognition requires payment.
  • The voice names are Jenny / Guy / Nanami / Xiaoxiao / Yunyang, clearly Azure neural TTS; the voices themselves are no moat.

Is differentiation why it took off? Only partly. What actually lifted it from 60 to 1,000 was "it became usable for non-Chinese users," meaning localization and language expansion. That is catching up, not differentiation. The course use case and sentence-level translation gave it a reason to be picked and kept among many undifferentiated YouTube dubbing extensions, and about 2,700 dubbings a week suggests the people who keep it are using it. But livdub (60k) and AutoDub (30k), listed around the same time with similar features, are far bigger, which shows that in this category distribution matters more than features, and EarDub's distribution has only just started.

6. Visibility and copycats

  • Almost nobody knows about it yet: revenue is not public, there's no media, no X posts, and 0 upvotes on Fazier.
  • Copycats: there isn't really anyone copying it; it is simply in an already crowded category. At least a dozen similar products were launched in 2026 (livdub, DubFlow, Dubingo, DubMog, FyDub, VoxTube, AnyDub, etc.).

7. Takeaways

  • Polish it for Chinese users first, then go global all at once (default language, 75 languages, multilingual UI, multilingual site). Each step maps to a user inflection point and is cheap to copy.
  • Within big categories, build vertical landing pages (Udemy translator, Coursera translator, English video to Hindi dubbing), plus reverse-demand pages riding platform news like "turn off YouTube auto-dubbing".
  • Start store titles with the category keyword, brand last.
  • Tier pricing by cost: free for subtitles, paid for speech recognition.
  • Turn your own tracking data into a "real numbers" blog: it's SEO content and trust proof at once.

8. Still unclear

  • When did the store title change, and did it come before or after the October surge?
  • Paid conversion and revenue.
  • 1,000+ growth: the store rounds it, so we can't tell whether it's still climbing after November.
  • How did livdub go from zero to 60k in 3 months? It deserves its own study. It may be the one that really broke out in this niche.
  • How much came from Google search (Brave ranks it low; actual Google rank not checked).
