Seller Nation-Ozon AI: up 8x in the store, but it's a hand reaching out from an ERP

What it is A free plugin for Chinese sellers doing Ozon: one-click collection of products from 1688, Taobao and Pinduoduo, AI rewriting of Russian copy and profit calculation, then direct listing or copy-listing to Ozon, backed by Seller Nation ERP membership.

Why it took off Seller Nation's ERP already had a batch of users; after the plugin hit the store in July, existing users and new sign-ups installed it following tutorials. On top of that, Chinese sellers' Ozon sales more than doubled over 2026, driving strong demand for listing tools.

CHow you could follow Don't build another Ozon collection plugin. If you want to learn from this, find a platform where Chinese sellers are just starting to flood in and which has no mature Chinese-language ERP yet; run the back end as paid membership, give the plugin away free as the entry point, and distribute through Bilibili tutorials, agents and Taobao activation codes.

Grade C: the growth rides on an ERP that already has users and on Ozon's platform tailwind, which late followers can't copy. Ozon collection-and-listing is already packed with Mabang, Dianxiaomi and dozens of plugins, so the thing to learn is how the companion plugin gets distributed. The small circle is talking about it

857 users

In 2026 Jul 16, a plugin called "Seller Nation-Ozon AI" went up on the Chrome Web Store. It hasn't been updated since Sep 4 2.3.3, yet its user count climbed from 112 to 6 872 by Nov. The curve looks like a new product taking off. In reality, a Chinese ERP that has been doing Ozon business since 2023 moved its existing collection plugin into the store. What it can teach you is how a "SaaS companion plugin" gets distributed, not an empty slot you can copy.

How a new seller actually installs it

In the "Beginner mode" of the official Yuque tutorial for Seller Nation (bcserp.com), installing the plugin is Chapter 2, placed after "How to become a BCS member." Start on the website and click "Free trial" to register. The sign-up page has a field called "Account manager code"; the tutorial's sample link is register?proxyCode=蟹老板. Fill it in and you're bound to an account manager, who handles activation, renewals and any problems.

Only then comes the plugin install, and the tutorial gives two routes. Method 1 comes first: download the plugin zip from the Ozon section of the website, unzip it, turn on "Developer mode" in your browser, and drag the folder in, with a reminder not to delete or move the plugin folder. Method 2 is searching "Seller Nation-OzonAI" in the Chrome store, followed by: "Plugins downloaded from the app store may not be the latest version; after installing, click 'Update now'." (Yuque tutorial, 11-06 read)

Once installed, open ozon.ru. A BcsOzon window pops up at the bottom right. Click "Quick login" and you can see each product's sales, category and commission rate. On a product page at 1688, click "One-click collect" and the item lands in the ERP's collection box. There's also "AI auto product selection": set the category, price range, quantity and keywords, turn on "Fully automatic mode," and it picks products on 1688 and lists them on your Ozon store by itself.

So the 872 people in the store are only the users who took the second route. The official homepage says "50k+ e-commerce sellers use it deeply" and "1M+ daily function calls" (self-reported, unverified).

What it is

In one line: a collection-and-listing plugin for Chinese sellers on Ozon. It collects products with one click from 1688, Taobao, Tmall and Pinduoduo, uses AI to rewrite Russian copy, calculates profit, and lists or follows-sells directly to Ozon. The plugin is free; the business behind it is ERP membership (personal or enterprise, activated online or by activation code). Advanced features such as the "X-ray eye" are marked Premium and require membership.

The store page has a detail worth noting. The short description says collection and listing, but the long description says "This tool focuses on cross-border e-commerce market data analysis... the plugin only provides data ranking browsing and will not read or retain any user browsing information." The long description of the same author's WB version is word for word identical. The permissions it actually asks for are cookies, tabs and scripting, plus 59 site rules, covering bcserp.com subdomains, 1688, and the image tool Yikeke (extops.dev permissions page). This long description looks like a generic template written to pass review (inferred).

The same author (listed in the store as the individual "Zhao Xiangling," not a trader) used the same template to publish four plugins, matching the four sites on the official website:

Add-onsLaunchedUsers (11-06)
Seller Nation-Ozon AI2026-07-16872
Seller Nation-WB AI2026-07-02206
Seller Nation-Mercado AI2026-07-1012
Seller Nation-Yandex AI2026-08-067

The matrix itself brings no traffic: whichever site has the most ERP users gets the most plugin users.

Why it's growing now

Store curve (public user counts from extops.dev): 9-04 112 people, 9-16 214,9-28 381,10-16 656,11-01 849,11-06 872. The fastest stretch ran from mid-September to mid-October, roughly +15 a day; in late October it slowed to 5 to 10 a day. It has had 0 ratings the whole time and never shipped a new version, so this growth wasn't driven by store recommendations.

Two forces stacked together:

  • Old users moving to the store version.The brand has existed for at least 2023 years. The Bilibili account "BCS Seller Nation" posted "Strongly recommend the super useful Ozon plugin... BcsOzon feature walkthrough" in 2023-07-20, a batch follow-selling video in 2023-11-27, and a BcsYandex plugin download-and-install video in 2024-12-15, with a dozen more after that: follow-selling, detecting unlinked listings, automatic order matching 1688 links. The store listing only appeared in July 2026. The tutorial lists it as the second installation method, so some newly registered sellers take that route.
  • Chinese sellers are surging on Ozon. Ozon says China-based sellers' turnover hit 2.1x year-on-year in Q2026, and its target for 2026 is to double cross-border GMV. New sellers' first move is to list at scale from 1688. 9, October saw the fastest growth, right before Russia's 11.11 and Black Friday restocking season (the timing lines up, but this is an inference).

Where users come from

Not a single yuan was spent on the Chrome store. Distribution followed the playbook common to domestic tools:

ChannelApproach
Account managers / agentsEnter an account manager code at sign-up or use a dedicated invite link; activation, renewal and support all go through that manager
Bilibili tutorialThe "BCS Seller Nation" account, a series since 2023, with a Bilibili collection pinned at the top of the Yuque docs
Yuque docsOne tutorial each for Ozon, WB, Yandex and Mercado, plus an automation tutorial
Selling activation codes on Taobao"BCS Seller Nation Premium" at ¥89, "OZON forced follow-selling software," personal monthly cards
Cross-border news sitesThe "Bcsozon" account on Dashu Cross-border posted 17 update logs, with 17.7k total reads
Fingerprint browser plugin hubsFeiqua browser listed "Seller Nation-Ozon AI product listing assistant," authorized per store employee; sellers running store networks install it there directly

Found no paid ads or influencer promotion, and no discussion on X, Reddit or HN. Douyin and Xiaohongshu searches returned nothing this time, so they're unverified.

Who it's competing with

Very crowded. Ozon's Chinese-seller tools are mostly "ERP + one plugin":

Seller Nation has nothing unique in its feature set: collection, AI Russian copy, profit calculation and follow-selling are all offered by rivals. Three differences are worth naming: it covers only Russian-speaking markets plus four Latin American sites; it goes deep on gray features such as forced follow-selling, detecting unlinked listings, and getting around the "copy restriction"; and it has a free tier with cheap paid plans. None of these explains why it grew on the store, though.

If it were you

C: you can learn something, but following isn't worth it.Its growth comes from an ERP that already has users plus the general expansion of Ozon sellers, and you have neither. In Ozon collection-and-listing, dozens of tools sit below Dianxiaomi and Mabang.

Who it suits:teams that already have a SaaS or ERP with a base of paying users and want to learn how to use a plugin as an entry point and how to claim more space in a store. Also people with a cross-border seller community and an agent network, looking for a new site the ERPs haven't filled yet.

Who it doesn't suit:independent developers who want to build a standalone "1688 → Ozon" collection plugin and grow it on organic store traffic. The store has no shortage of these plugins, the users are tied to ERPs, and the plugin alone can't collect money.

How to do it:If you really want to, skip Ozon and WB and look for a platform that Chinese sellers are just starting to flood into and that has no mature Chinese-language ERP yet. (The Mercado version has only 12 users, which suggests Seller Nation itself hasn't got Latin America going, inferred.) Start with a small ERP or order back office. Keep the plugin free as the collection client and entry point, and collect money from memberships: personal, enterprise and activation codes. Gray follow-selling features make money fast, but they can stop working the moment a platform introduces new rules, so don't treat them as the main course.

How to get users:Copy its approach: a Bilibili video series, Yuque docs, activation codes sold on Taobao, agents and account managers for store networks, and listings in fingerprint browser plugin hubs. The Chrome store is just one install channel, so don't expect it to bring volume.

When to get in early:Follow the platform's recruitment timing. The window is roughly the first six months after a new platform starts actively recruiting Chinese sellers. Once Dianxiaomi and Mabang announce integration, you're late.

What would show you're wrong:① The Seller Nation-Ozon AI listing starts collecting a lot of ratings, or passes several thousand users through store recommendations. That would mean the store itself has organic traffic, and a standalone plugin could work. ② The Mercado or Yandex version reaches hundreds or thousands of users within a few months. That would mean it has taken off in Latin America or on Yandex, and those spaces are already claimed. ③ Ozon cracks down on follow-selling and copy-type tools and Seller Nation's core features stop working. Then the whole track reshuffles, and that could open new opportunities.

Why the Seller Country–Ozon AI Chrome extension (khbkldlanemijjpgednfhcpfgbmkjncl) took off

Research date 2026-11-06. Data comes from our chromestore database, the extops.dev page, the store listing, the bcserp.com official site, and web pages on Bilibili, Dashu Cross-border, Taobao, and Feiqua Browser.

Bottom line

It did not take off on its own. It is the companion collection plugin for BCS Seller Country (bcserp.com), an Ozon/WB ERP. The brand has been posting BcsOzon plugin tutorials on Bilibili since 2023, and only formally put the plugin on the Chrome Web Store in 2026-07. Store users grew from 112 to 872, driven by existing ERP users and new sellers installing the plugin following tutorials, not by organic store traffic. The plugin itself is free; the money comes from ERP subscriptions (the "Advanced Edition" on Taobao at about ¥89, the "personal monthly card"), riding the wave of 2025–2026 when large numbers of Chinese sellers poured into Ozon.

1. What the product is

  • Store description: one-click collection of products from 1688, Taobao, Tmall, Pinduoduo, and Ozon, listing directly to Ozon, with AI-optimized Russian copy, a profit calculator, and Russian localization. (Store listing page, read 2026-11-06)
  • Long description doesn't match the summary: the long description says "This tool focuses on cross-border e-commerce market data analysis… the plugin only provides market ranking browsing and will not secretly read…" The same author's "Seller Country–WB AI" long description is word-for-word identical. (Store page; chromestore database item table) This looks like a generic template written to pass review; the actual permissions request much more.
  • Permissions: cookies, tabs, scripting, activeTab, alarms, storage, plus 59 site match rules, including all bcserp.com subdomains (ozon./vision./pre.), yiketu.com/.art (Yiketu, an image tool), and *.1688.com. (extops.dev permissions page) In other words, it reads 1688 pages and then writes the data into the Seller Country ERP's web pages.
  • Version 2.3.3,2026-09-04 updates; author "Zhao Xiangling", email [email protected], not a trader; privacy policy at privacy.bcserp.com; 0 ratings.
  • The same author has 4 extensions built on the same template: WB AI (2026-07-02,198→206 users), Ozon AI (2026-07-16,872 users), Mercado AI (2026-07-10,12 users), Yandex AI (2026-08-06,7 users). (Extops author page; chromestore database item_snap) These four line up exactly with the four "platforms" on the official site: Ozon, Wildberries, Yandex, Mercado.

  • Has held a 0 rating the whole time; no sign of solicited or fake reviews.

3. Where users come from (growth tactics)

  1. ERP user migration and install with ERP activation (main channel, inferred, strong evidence). The official site bcserp.com claims "50k+ e-commerce sellers use it deeply" and "1M+ daily feature calls", with a "free trial", a pricing page (visible only after login), and Yuque tutorials (Ozon beginner tutorial, WB/Yandex/Mercado tutorials). The plugin's site permissions are exactly bcserp's own subdomains, so the purpose of installing it is to collect and list goods through the ERP. The store has fewer than 900 users, far below the claimed 50k sellers, which suggests most users installed it from somewhere else.
  2. Bilibili tutorials (confirmed). The account "BCS卖家国度" (space.bilibili.com/3546758256789996) has a series of tutorials: "Strongly recommend the super useful ozon plugin... BcsOzon feature walkthrough" (2023-07-20), "BcsOzon bulk follow-selling, stock setup, one-click follow-sell all variants" (2023-11-27), "3. BcsYandex plugin download and install" (2024-12-15), plus a dozen-plus more on follow-sell rework 1688 scraping, detecting unfollowed listings, auto-matching order links 1688, auto-reminding passport info fill-ins and more. The brand and plugin have been around since at least mid-2023, and the one on the Chrome Web Store is the 2026-07 release.
  3. Cross-border news site content (confirmed). Dashu Cross-border (10100.com) has a "Bcsozon" account with 17 articles and 17.7k total reads, mostly version update logs; for example, the 2025-08-02 article covers "a temporary workaround for BCS's copy ban". AI navigation sites such as Feiyu AI Navigation and PMKG also list BCSOzon.
  4. Taobao activation and subscriptions (confirmed). Taobao has "BCS卖家国度 Advanced Edition Ozone cross-border and domestic all-purpose order-boosting tool" at ¥89, "BCS卖家国度 OZON forced-copy software", and "personal monthly card" (Taobao Baike 2026-10-12). A Russian seller site has an article titled "bcs+ozon analytics system activation code". This indicates it is going through activation-code and agent distribution channels.
  5. Fingerprint browser plugin center (confirmed). Feiqua Browser's plugin center lists "卖家国度-Ozon AI上品助手", authorized at the store-staff level. Sellers running store farms often use this kind of fingerprint browser, and the plugin is distributed directly inside it, bypassing the Chrome Web Store.
  6. Platform event (timing, background confirmed). Ozon officially says Chinese sellers' Q2 2026 turnover grew 2.1-fold year over year (seller.ozonru.cn), and its 2026 target is to double cross-border GMV (Sina 2026-04-24). By the end of 2024 it had signed at least 100k Chinese sellers (letschuhai). When new sellers flood in, they need tools to list and forced-copy from "1688 → Ozon". 9–October growth was fastest, right in the restocking and new-listing season before Russia's 11.11 and Black Friday; this correlation is inferred.
  7. Not found: paid ads, influencer promotion, discussion on X/HN/Reddit, media coverage. The TikHub interfaces for Douyin and Xiaohongshu returned no results this time, so these remain unverified.

4. Competitors

Collection, bulk listing, and forced-copy tools for Chinese Ozon sellers are a crowded red ocean, mostly ERPs bundling a plugin:

(Store users: chromestore database 2026-11 snapshot)

5. Differentiation

  • Nothing unique in features: one-click scraping 1688, AI Russian copywriting, profit calculation, copy-listing. Miaoshou, DianxiaoMi and Shangpinbang all have these.
  • Differences worth noting: ① it covers only four "Russian-speaking + Latin America" sites (Ozon / WB / Yandex Market / Mercado), with one plugin and one subsystem per site; ② grey features like copy-listing and anti-copy-listing are built deep (forced copy-listing, patrolling for delisted items, generating complaint text, bypassing the "copy ban"); ③ there is a free tier ("0 cost + the best free features on the web") and the paid tier is cheap (Taobao ¥89 tier).
  • These differences are not why it grew on the Chrome Store. The store curve is ERP users migrating into this newly listed plugin, plus Ozon's Chinese sellers expanding overall.

6. How visible it is

  • Revenue is not public; TrustMRR and the founders have not posted it, and it is not mentioned on X or in media. It has some name recognition in the Chinese Ozon seller circle (Bilibili tutorials, Dashu Kuajing, Taobao, fingerprint-browser plugin hubs), which makes it "whispered about in a small circle."
  • The niche itself is already crowded (dozens of Chinese ERPs and plugins), so it is not an undiscovered gap.

7. Takeaways

  • Companion-plugin play: the main product is a SaaS or ERP, and the plugin is just an entry point and collection client. The plugin is free, the generic description passes review, and users steadily come from the SaaS itself. So the rise in store users reflects the main product pulling in new users; it should be read alongside the main site.
  • One template copied into a multi-site matrix: the same code with the site name swapped yields WB, Yandex and Mercado versions at almost zero listing cost. But the other three have only 7–206 users, showing the matrix itself does not bring volume; volume follows where the main site has users.
  • A common domestic tool distribution mix: Bilibili tutorials + Yuque docs + selling activation codes on Taobao + fingerprint-browser plugin hubs + WeCom customer service, relying entirely without Chrome Store organic traffic.

8. Uncertain

  • "50k+ sellers" is self-reported on the official site and unverified; paid-user counts and pricing page content (behind login) were not seen.
  • How the plugin was distributed before 2026-07 (crx offline package, fingerprint browsers, or an old store listing since removed) is unverified; no earlier BcsOzon store entry is in our database.
  • Whether it is an official Ozon partner is unverified. Douyin and Xiaohongshu ads and content were not found this time (the API returned nothing).
  • It is unclear which specific Ozon restriction "BCS copy ban" refers to, which may affect how long its core copy-listing feature can survive.
