Yiban

What Yiban does

Yiban (壹伴), operated by Wuhan Nightingale Technology Co., Ltd. (武汉夜莺科技有限公司) and headquartered in Wuhan, China, is a software company that builds a Chromium-based browser extension embedded inside the WeChat public account backend (mp.weixin.qq.com). The plugin adds one-click article formatting, AI-assisted writing (long-form generation, short-text rewriting, title generation/optimization, and title scoring against a corpus of 300+ million titles), material sourcing from a library of 200M+ images/GIFs/emoticons and 200,000+ style templates, real-time article and fan-growth analytics across 30+ metrics, compliance detection across five sensitive-content categories, batch fan-message handling, scheduled mass-sending (Yiban Mass Sender), and a cloud material library (Yiban Cloud Notes). The product portfolio also extends into enterprise WeChat marketing via the separate weibanzhushou.com property and includes integrated image-design partnerships with Gaoding Design, Fotor, and Chuangkit.

The company monetizes through a freemium model with two paid annual subscription tiers — Standard VIP and Advanced VIP (the latter gated to WeChat-certified accounts and adding enterprise features such as channel QR codes, customer push, auto-tagging, and fan-retention analytics) — supplemented by a referral/rewards program and indirect monetization through its enterprise WeChat marketing tools. Yiban claims a user base of 4 million+ WeChat public account operators and is privately held, with no disclosed institutional funding and 11–50 employees. The company was founded by Xiao Hong (肖弘), who has subsequently founded Monica AI and Manus AI; ownership is founder-controlled with no public cap-table information.

Distribution is product-led and self-serve: users download the .crx from yiban.io or install from the Chrome Web Store, QQ Browser Store, 360 Browser Store, and other Chinese browser stores, supported by content marketing through the company's WeChat Public Account Guide blog, Zhihu and Sohu columns, SEO for WeChat editor/operations keywords, and a friend-invitation reward program. The target customer is the long tail of individual and small-team WeChat public account operators, with a secondary enterprise-marketing-teams segment served via the Advanced VIP tier and the Enterprise WeChat marketing property.
