Analysis
Zhihu sits at a unique intersection: it's where Chinese professionals go to demonstrate expertise and where curious people go to learn. The platform's trending questions (Zhang Xue at 4.3M views, Italy at 10M views) are leading indicators of what educated Chinese people care about.
For AI development, Zhihu's content is invaluable. High-quality Q&A pairs in Chinese are relatively scarce compared to English. Zhihu's corpus — spanning technical, business, and cultural domains — represents one of the richest Chinese-language knowledge resources. The platform's AI integration (summarization, recommendations) makes this knowledge more accessible while creating new revenue streams.
The challenge is maintaining quality as the platform scales. Zhihu has struggled with content quality degradation (increasing marketing answers, decreasing expert participation). If AI tools can help identify and surface the best answers, quality could recover.
