Baike.com: What Is It?

Baike.com is a Chinese-language, user-editable online encyclopedia and social network. Registered users can create and edit entries, and the platform has historically included chat forums, fan groups, and a credit-point system that rewards frequent contributors with redeemable gifts. It was one of the two largest wikis in China during the 2000s and 2010s, alongside its longtime rival Baidu Baike.

The platform began in 2005 as a direct emulation of Wikipedia; founder Pan Haidong stated in 2009, "Of course we are a copycat of Wikipedia," while arguing the site had its own distinct features. The company also built its own wiki software, HDWiki, as an alternative to MediaWiki, and released a classifieds product called YELLOWIKI. Unlike Chinese Wikipedia, which was intermittently blocked in China for extended periods, Baike.com operated without that restriction and grew rapidly through the late 2000s.

Since ByteDance's 2019 investment, the platform has been folded into ByteDance's content and search ecosystem. Its brand has changed multiple times — from Toutiao Baike to Kuaidong Baike to Douyin Baike — reflecting successive integrations with ByteDance's Jinri Toutiao news aggregator, Toutiao Search, and the Douyin short-video app. As of 2024, the underlying domain, baike.com, is publicly branded as Kuaidong Baike (快懂百科) on desktop and Douyin Baike (抖音百科) inside ByteDance's mobile apps.

Baike.com: Disambiguation

Baike.com should not be confused with the following entities:

Baidu Baike (百度百科): Baike.com's principal and longtime rival, owned by Baidu and founded in 2006. Baidu Baike is the larger of the two platforms by traffic and entry count and has been the plaintiff in multiple lawsuits against Baike.com's operator.
Chinese Wikipedia (中文维基百科): A nonprofit, community-governed encyclopedia operated by the Wikimedia Foundation. Baike.com is a for-profit commercial company with editorial and content-moderation practices that differ from Wikipedia's, and it has faced repeated allegations of copying content from Chinese Wikipedia and other sources.
Sogou Baike (搜狗百科): A separate Chinese wiki encyclopedia historically associated with Sogou/Tencent, distinct in ownership and operating company from Baike.com.
Qiuwen Baike (求闻百科): A nonprofit Chinese-language encyclopedia created after 2021 by former Chinese Wikipedia contributors; unrelated in ownership to Baike.com.
BaiduWiki: A multilingual, AI-translated international edition of Baidu Baike launched by Baidu in January 2026. It is a separate Baidu product, not a Baike.com or ByteDance product.

Baike.com: Frequently Asked Questions

What is Baike.com?: Baike.com is a Chinese-language, user-editable online encyclopedia founded in 2005 by Pan Haidong. It was originally called Hudong Baike (互动百科) and is now owned by ByteDance, currently operating under the brand names Kuaidong Baike (快懂百科) on the web and Douyin Baike (抖音百科) inside ByteDance's apps.
Who owns Baike.com now?: ByteDance has controlled the platform since it invested RMB 8.1 million for a 22.2 percent stake in August 2019, becoming its largest shareholder. The site's registered operating company remains Beijing Hudong Baike Network Technology Co., Ltd., as listed in the site's own copyright notice.
Is Baike.com the same as Baidu Baike?: No. Baike.com and Baidu Baike are separate, competing companies. Baidu Baike is owned by Baidu and was founded in 2006; Baike.com was founded in 2005 by Pan Haidong and is now owned by ByteDance. The two platforms have been involved in multiple lawsuits against each other.
Why did Baike.com change its name so many times?: The platform has been renamed repeatedly to reflect changes in ownership and corporate strategy: from Hudong Weike (2005) to Hudong Baike, then to Baike.com (2012), then to Toutiao Baike (2020) after ByteDance's involvement, then to Kuaidong Baike (2021), and finally to Douyin Baike (2023–2024) as ByteDance integrated it into the Douyin app, with the PC website reverting to the Kuaidong Baike name in September 2024.
What happened in the 2017 CCTV 3.15 Gala controversy?: China Central Television's annual consumer-rights broadcast reported that Hudong Baike allowed users to pay a fee to publish entries with little editorial oversight, including a fabricated entry claiming a supplement cured cancer. The exposure damaged the platform's credibility and was followed by a steep drop in its reported annual profit.
What was the 2025 lawsuit between Baidu Baike and Douyin Baike about?: In May 2025, a Beijing court (Haidian District Court) found that the operator of Douyin Baike had scraped more than 600,000 entries from Baidu Baike and fabricated user data to make the copied content appear to be organic user submissions. The court ordered the operator to pay Baidu 8 million yuan in damages and expenses, and the case was named among the court's top intellectual-property disputes of the year.
How large is Baike.com's encyclopedia today?: As of 2024, the platform's Chinese Wikipedia entry reports approximately 8 million entries, accessible through ByteDance products such as Douyin and Toutiao Search. This is smaller than Baidu Baike, which reported more than 28 million entries as of 2025.
Was Baike.com ever a publicly traded company?: Yes, in a limited sense. The operating company listed on China's National Equities Exchange and Quotations (NEEQ), a secondary "New Third Board" market, in February 2016 under stock code 835799. Trading was suspended in March 2017 following the CCTV controversy, and the company delisted in August 2018, before ByteDance's 2019 investment.
