Watcha

Watcha (Guan Cha) is an AI product community and review platform operated by Hangzhou Siyi Technology Co., Ltd., known as the Dianping of AI products, stitching together a Chinese-language community through its product catalog, long-form reviews that can be negative, and developer services, serving AI enthusiasts, independent developers, and industry observers who want the unvarnished truth.

Core Capabilities

• Product catalog: 2,743 AI products filterable across 15 categories like general assistants, image, video, and coding — the main discovery entry point
• Scores and reviews: 0–10 word-of-mouth scores plus Good/Bad long-form reviews, with review rights requiring invitation or passing the 50-question reviewer exam
• Watcha Hall and rankings: plaza discussions, weekly hot lists, fastest-rising reputation list, active user rankings, and topic tags
• Personalized exploration queues: the homepage generates recommendations by user profile ('we matched 12 products for you') rather than a static directory
• Seeds and melon sheds: post and check in to earn seeds, redeemable for beta codes, discount codes, and merch — not a cash paywall
• Events and academy: the Watcha conference, hackathons, and free co-learning camps (study.watcha.cn), plus a public JSON API at /api/v2/products and an iOS app

Use Cases Suited to AI power users who want real long-form reviews and to avoid advertorials, independent developers and OPCs needing cold-start seed users and feedback, and product managers and investors who treat the community as an industry signal source; casual users who just want one-click jumps to official sites are better served by traditional directories.

Unique Advantages Against Product Hunt and the many directory sites, Watcha delivers in-depth Chinese reviews and a word-of-mouth system where negative reviews can be published, layered with a two-sided network, gated review admission, and developer infrastructure. Note: the same company's TokenDance (tokendance.space) is a model API gateway from the Watcha ecosystem and a completely different product form — do not conflate them. The platform is backed by Sequoia China + China Renaissance seed funding and has been covered by CCTV's Economic Half Hour, with its homepage and iOS app (v1.0.11) still updating as of 2026-09-17 — among the strongest endorsement tiers of domestic communities.

Editorial Review As the strongest candidate for China's Product Hunt, Watcha's product surface and ecosystem completeness merit inclusion. But honest caveats: official revenue comes from advertising and channel fees and part of the review incentives are funded by AI product makers, yet no 'ad' labels appear on site — neutrality is in tension; the Watcha trademark itself is not yet registered, and class 38 has been registered by an unrelated Beijing company; the user agreement still says 'no account deletion service,' out of step with the deletion entrance already live in the app; plus UGC copyright and subjective scoring, name conflicts with Guancha.cn (Observer) and Korea's WATCHA, and team-size figures ranging across 14/16/24 people.
