Sogou: What Is It?

Sogou is a Chinese internet company that operates a search engine, develops input method software, and provides vertical search services. The company was founded in 2004 as part of Sohu.com and became independent in 2010. As of September 2021, Sogou is a wholly owned subsidiary of Tencent Holdings Limited after Tencent completed its acquisition of the company.

Sogou's search engine provides general web search, image search, news search, and specialized vertical search options in domains such as medical information, legal content, and educational resources. The company's most recognized product is Sogou Pinyin, a Chinese character input method editor that became the dominant input platform in China for both desktop and mobile devices, serving hundreds of millions of users. Sogou also operates WeChat Search, which provides exclusive access to indexing and searching WeChat public account content—a capability no other search engine possesses.

Sogou's primary technological focus areas include voice search, artificial intelligence for language processing, input method development, and integration with Tencent's ecosystem products including WeChat and QQ. The company maintains research and development centers in Beijing, Chengdu, and Guangzhou. Since Tencent's acquisition in 2021, Sogou operates as part of Tencent's Platform and Content Business Group (PCG), though it continues to maintain its brand identity and operate dedicated search and input method services.

Following its acquisition by Tencent, Sogou discontinued certain hardware and services. In 2022, Sogou discontinued its map services. In May 2024, Sogou officially ended its hardware product services, marking a strategic shift away from hardware offerings while maintaining its core search and software platform services.
