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.

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.

The product is currently free to use, and anyone can open and use it directly.
