Zhida's real differentiator is traceability: answers cite specific Zhihu contributors and posts rather than vague web sources, which cuts down on the made-up-citation problem generic AI search tools have. Since integrating DeepSeek-R1 for its deep-thinking mode, and adding a "professional search" pass over Wikipedia, Zhihu Select, and a 50 million-plus Chinese/English paper corpus, it's become a genuine research tool rather than just a Q&A wrapper. Penetration has grown fast — Zhihu says it nearly quadrupled year over year by Q3 2025. The tradeoff is quality inheritance: answers are only as good as Zhihu's own content on that topic, so niche or fast-moving subjects with thin community coverage still produce shakier results, and it remains Chinese-first with no public API. Worth using specifically for Chinese-language research and opinion-heavy questions where you want a named source, not blind trust in the answer.
What people say
Zhihu launched Zhida on June 29, 2024, betting that its long history of community Q&A content could differentiate an AI search product in a market already crowded with Baidu, Doubao, and DeepSeek's own chat interface. The wager appears to be paying off on engagement: Zhihu says Zhida's penetration rate topped 15% by Q3 2025, close to four times where it stood a year earlier, and the company credits AI search broadly with double-digit growth in retention and engagement across its apps.
The product now runs DeepSeek-R1 in what Zhihu calls a "fully powered" integration for its deep-thinking mode, layered on top of Zhihu's own content. A "professional search" mode, added more recently, adds file upload and long-document parsing, plus the ability to point a query at a specific source — Wikipedia, Zhihu Select, a combined Chinese/English academic corpus the company puts at 50 million-plus papers, or a personal knowledge base built from your own uploads, bookmarks, and RSS feeds. Answers come in brief or in-depth modes, and a recent upgrade added source-to-person traceability — linking a claim back to the actual Zhihu contributor and post it drew from, rather than a generic citation — specifically to cut down on fabricated sourcing.
That traceability is the real selling point over generic AI search: because Zhida can point at a named, real answerer with an upvote count, it's harder for it to hallucinate a source the way pure web-scraping tools sometimes do. Zhihu's own coverage of the product frames this explicitly as a hallucination-reduction strategy.
It's not friction-free. Users report that switching browser tabs kills an in-progress answer stream because the product doesn't keep the connection alive in the background — you have to stay on the page. There's no way to @-mention or follow a Zhihu author directly from within Zhida. Query understanding can also misfire on specific-entity questions: one documented example has a user asking to evaluate a named contributor's answers, and Zhida parsing "Zhihu," "contributor," and the person's name as three separate keywords instead of resolving the actual profile, returning scattered, only loosely relevant results. Specialist and fast-moving topics still produce occasional fabricated details despite the sourcing upgrades. There's no public API, and it's built for a Chinese-reading audience — the interface and content base are Mandarin-first even where it can process English academic sources.
