猜盐

它在赌什么任何真实世界的信息都可以变成可分享的猜谜游戏,而让用户自我表达(而非付费广告)才是独立产品传播的关键。已上线

做的是什么生意

CaiYan (猜盐), a pun meaning both 'guess the salt' and 'quiz', is a Chinese WeChat (微信) mini-program and web platform with dozens of AI information games — Guess the Disease, Guess the Country (猜国), Guess the Word (猜词), Guess the City (猜城), Guess the Song (猜歌), Guess the Cute (猜萌) — where players interrogate an AI patient or infer answers from clues, and daily challenges; it was incubated in 2022 by one-person-company founder Zhang Yue.

启动资金Bootstrapped: no investment raised as of 2026-04; the founder cites monetization from the launch year, 2023 revenue above ¥100k, and a ¥3M revenue target for 2026, with a team of one full-time founder plus two part-time students.

起因

Zhang Yue, a computer-science graduate (two ACM Asia-regional bronzes, a national programming prize) who worked at Alibaba for years, first built the solo game Tuxun (图寻), which asks players to locate a place from street-view images and passed 1M+ users but was limited to geography. In October–December 2022 he incubated CaiYan to repeat the 'guess from information' loop across history, medicine, words, cities, songs and other domains.

经过

CaiYan monetized from its launch year (2023 revenue above ¥100k) and kept adding modes. In May 2025 its Guess the Disease mode — the player is the doctor and an LLM plays a patient ordered not to reveal its illness — went viral as players shared interrogation screenshots on Xiaohongshu, turning diagnosis into an 'AI jailbreak contest'. Red Star News (红星新闻) found doctors and medical students using the game as a diagnosis drill, and the founder said its positioning was entertainment plus education. By the 2026-04 interview the platform had passed 1.6M cumulative users with a 200k DAU peak, over 30% next-day retention, revenue tripled in 2025, and a ¥3M target for 2026 — still run by one full-time founder, two part-time student helpers and about 10k core users in a QQ group.

结果

Still live and profitable as of 2026-09-02: bootstrapped and solo-run; the founder presented at Chengdu's first OPC investor roadshow in March 2026 with talks underway but no round closed.

背景

猜盐是一个中国问答游戏平台,几乎由一人打造并运营,即前阿里巴巴工程师张月。其数十种玩法将真实世界信息转化为猜谜游戏——从图片猜城市、从歌词猜歌曲、猜国家、猜词——其中爆火的是“猜病”,玩家扮演医生,AI扮演不能透露病情的患者。

故事始于张月的“图寻”游戏,类似GeoGuessr的街景定位游戏,用户超过100万,但市场有限。2022年底,他孵化猜盐,将“根据信息猜测”的机制推广到多个领域;上线首年即实现盈利,2023年收入超过10万元,随后在2025年迎来病毒式传播。

2025年5月,猜病在中国社交媒体上走红,玩家纷纷分享荒谬的调查截图——PUA AI、越狱其提示词,甚至说服其坦白——知名科技账号“差评”将其称为“AI越狱竞赛”。据报道,医生和医学生将其作为诊断实践,张月称产品旨在寓教于乐。

截至2026年4月5日《中国经营报》采访,平台累计用户超过160万,零付费推广,日活峰值20万,通常维持约2万日活,次日留存率超30%,2025年收入增长两倍,2026年目标300万元——由一名全职创始人、两名兼职学生和约一万QQ核心用户运营。

这件事要成立,得有什么

  • 猜病颠倒了一种熟悉的形式——AI是患者,用户是医生——为玩家提供了全新的幽默和角色扮演舞台。
  • 用户生成的诊断帖子将这个游戏带到了小红书等平台,对于没有营销预算的创始人,实现了零成本推广。
  • 图寻的100多万用户验证了“根据信息猜谜”的玩法,之后猜盐将其推广到几十个领域。
  • AI消除了内容瓶颈,使得一人运营一个通常需要内容团队的平台成为可能。
  • 每日单人挑战和高难度制造了稀缺性和炫耀资本,驱动了回访和分享。

可借鉴之处

产品即广告:当游戏为用户提供幽默和自我表达的舞台时,用户的帖子实现了独立创始人无法负担的推广。

后续进展

截至2026年9月2日,猜盐仍在运营且盈利,自力更生且单人运营。在2026年4月累计用户超过160万、日活峰值20万、次日留存率超30%之后,张月设定了年收入300万元的目标,仍只有一名全职创始人和两名兼职学生,并运营一个约一万人QQ社群。他于2026年3月参加了成都首届OPC投资者路演;已有洽谈但未完成融资,他质疑风投是否适合这样一个小而垂直的个人产品。剩余风险包括:趋势驱动的玩法、LLM更新吸收功能以及激烈竞争。
