Baidu Wenku: What Is It?

Baidu Wenku is a document-sharing and content-creation platform operated by Baidu, Inc. Users upload documents, which Baidu reviews before publication, and other users can read them online or download them; uploaders earn points for contributions, and downloading priced documents consumes points. The platform supports common file formats, including .doc/.docx, .ppt/.pptx, .xls/.xlsx, .pdf, .txt, and several others.

Since an August 2023 restructuring, Baidu Wenku has operated as an AI-assisted "one-stop" content platform, layering generative features on top of its existing document library. These features include automated PPT generation, document drafting, mind-map creation, research-report generation, and AI-assisted illustration and comic creation, powered by Baidu's ERNIE large language model. In 2025, Baidu paired Wenku with Baidu Netdisk to launch "Cangzhou OS," a content-domain operating system, and a general-purpose AI agent called GenFlow, which has been updated through multiple versions.

Baidu Wenku is used by students and researchers searching for reference materials and past coursework, by teachers sharing instructional resources, by office workers producing presentations and reports, and by content creators monetizing original documents through the platform's points and revenue-sharing systems.

WPS Office (Kingsoft WPS): A competing Chinese office-software suite whose smart-PPT feature competes directly with Baidu Wenku's; WPS held about 14.6% of China's smart-PPT market as of mid-2024, compared with more than 80% for Baidu Wenku, per industry data.
