China's Quora: Zhihu vs Quora — The 2025 Comparison
Zhihu (知乎) is China's premier question-and-answer platform, often described as China's Quora. Founded in 2011, Zhihu has grown from an invitation-only knowledge community into a public platform with over 100 million MAU. While Quora has struggled to monetize, Zhihu has diversified into education, e-commerce, and content付费订阅. However, Zhihu faces its own challenges — FY2025 revenue declined 23.6 percent as it pivots its business model.
TL;DR
Zhihu has over 100 million MAU and reported FY2025 revenue of 2.749 billion yuan ($376 million), down 23.6 percent year-over-year as the company scaled back loss-making businesses. Reddit reported $2.2 billion revenue in 2024 (up 69 percent) with 1.3 billion MAU. Zhihu's content quality is generally considered superior to Quora due to its expert-contributor model, but Zhihu faces challenges balancing content quality with commercial growth.
Key Insights
Zhihu: China's Knowledge Community
Zhihu reported FY2025 revenue of 2.749 billion yuan ($376 million), a 23.6 percent decline as the company exited unprofitable businesses. Zhihu has over 100 million MAU with high engagement among educated urban professionals. The platform is known for detailed, expert-level answers on technology, science, career advice, and social issues. Zhihu has expanded into paid content (盐选专栏), vocational education (职业教育), and book publishing. The company went public on NYSE in 2021 and dual-listed on HKEX in 2022.
Quora: The Global Q&A Pioneer
Quora has an estimated 400 million monthly active users globally. Unlike Zhihu, Quora has struggled with monetization — its primary revenue source is advertising, supplemented by Quora+ subscriptions ($6.99/month for ad-free access and exclusive content). Quora launched Poe, an AI chatbot aggregation platform, which has become a significant growth driver. Quora has been criticized for declining answer quality due to AI-generated content and spam. For comparison, Reddit (a related platform) reported $2.2 billion in 2024 revenue.
Content Quality: Zhihu's Strength
Zhihu maintains higher content quality than Quora due to several factors: its early invitation-only model attracted industry experts and academics; detailed long-form answers are rewarded through upvotes and visibility; and the platform actively moderates low-quality content. Zhihu's '盐选' (Salt Select) paid content program has attracted professional writers creating serialized fiction and in-depth guides. However, Zhihu has faced criticism for declining quality as it pursued user growth, similar to Quora's experience.
