What is Zhihu Zhida?

Zhihu Zhida is an AI large model search product launched by Zhihu. Its official positioning is an efficiency tool based on the Zhihu community and supplemented by a variety of data sources, targeting professional and popular science users with low entertainment value. Different from general search engines, it is built on Zhihu's self-developed Zhihai Chart AI large model at the underlying level, and prioritizes calling the high-quality Q&A content accumulated on Zhihu's platform to organize answers. In addition to extracting answers from community content, the official states that it will also integrate articles from other websites to provide more complete references. At the same time, it is not just "finding content", but also "finding people" — it also brings out relevant professional answerers and connects back to the Zhihu community. The product is currently free to use, and anyone can open and use it directly.
