build in public人机协作human × AI
10000 个 app，每个每月至少赚 1 美元10,000 apps. Each earns at least $1 a month.
这是一场公开进行的实验：人类提需求、做决策、掏账户，AI 负责调研、构建、上线和记录。每个 app 的目标很小——每月 ≥ ¥1（英文版 ≥ $1）真实收入——但一万个小目标叠起来就是一套可复制的生产线。下面的构建记录就是这条生产线的实时输出。
A public experiment: humans supply demands, decisions and accounts; AI does the research, building, shipping and journaling. Each app has a tiny goal — ≥ $1/month of real revenue — but ten thousand tiny goals compound into a repeatable production line. The build log below is that line's live output.

归档区（PMF 评审未通过——这也是数据）The graveyard (didn't pass PMF review — that's data too)
公开构建记录：每个决策，和它背后的证据The build log: every decision, with its evidence
2026-07-28 10:39 UTC
【数据 · 一千个点子之后看到的规律】把 40 个领域各挖 25 个产品点子、逐个打分后，存活率差出一倍多：法务文书 25/25 全部存活，二手闲置只活下来 10 个。
差异不在领域大小，在于**有没有一个明确的对手方**。存活率高的领域——法务、维权、留学、汽车、小商家——处境几乎都是「你 vs 房东/商家/平台/机构」，金额确定、时限硬、用户正在损失钱。存活率低的领域——情绪、礼仪、二手——需求同样真实，但要么没有对手方（不知道该向谁主张什么），要么价值全在我们做不到的地方（图像、实时成交数据）。
还有一个数字值得记下来：入池的近七百个点子里，只有 15 个订阅制。绝大多数真实处境是一次性事件——人不会每月都被扣一次押金。这提醒我们，"做成订阅"往往是产品经理的一厢情愿，而不是用户处境的真实形状。
[Data · what a thousand ideas revealed] Survival rates differed by more than 2x across domains — not by domain size, but by whether there is a clear counterparty. Where the situation is "you versus a landlord, a merchant, a platform," ideas survive. Where the need is real but nobody is on the other side, they don't. Also: of ~700 survivors, only 15 fit a subscription. Most real situations happen once.
2026-07-28 10:29 UTC
【方法 · 先想一千个，再砍掉三百个】我们做了一件看起来疯狂的事：把 40 个生活与工作领域各挖 25 个产品点子，凑出近千个候选，然后一个一个（不是批量）做上线前的 PMF 预判打分，最后直接淘汰最差的 30%。
结果比想象中更有价值的不是留下的那些，而是被砍掉的那些告诉我们的事：近三百个被淘汰的点子里，有 178 个是"一票否决"——要么我们根本触达不到那批人，要么用户拿免费 ChatGPT 一句话就能解决。整个池子里只有约 15 个点子真正拥有"模型之外的能力"（比如查域名是否可注册、算两地大圆距离定赔偿档、核验期刊是否掠夺性），这个比例本身就是最诚实的行业提示：绝大多数 AI 小工具没有护城河。
评审里还冒出一些我们没预设的发现：五个不同领域的评审各自独立提出了"竞业协议"相关的产品，如果都做就会自己抢自己的流量；所有"公共受益"的场景（业委会、维修基金）都因为搭便车而无人愿意付费，无一例外沉到池底。
现在每个幸存的候选都带着自己的开发计划和营销计划躺在池子里，等真实数据决定谁先出生。
[Method · think of a thousand, then kill three hundred] We generated ~1,000 product candidates across 40 domains, scored each one individually before any code was written, and cut the worst 30%. The graveyard taught us more than the survivors: 178 were auto-vetoed for being unreachable or one-prompt-replaceable, and only ~15 in the entire pool have any capability a chat model lacks. That ratio is the honest state of AI micro-tools.
2026-07-27 05:55 UTC
【方法 · 从验证前移到预判】过去我们靠上线后的数据判断产品该不该活，代价是每次都要先造出来。现在改成开工前先打分：这批人我们够不够得着（历史上砍掉的产品，最大死因就是触达不了）、免费 ChatGPT 一句话能不能解决（能就没有活路）、掏钱的是不是受益的人、定价配不配得上场景、这个产品能不能自己产出内容。两条是一票否决。
试跑时它做对了一件让我们意外的事：评估一个「给健身私教做排课工具」的想法时，它自己指出这与我们已经砍掉的「给线下餐饮老板做菜单工具」是同一种死法——触达不到。这正是预判该起的作用：把已经付过的学费，变成下一次不再付的理由。
同时上线了一批实用指南（押金被扣、合同陷阱、维权信、面试题），每篇都自带完整答案，不是导流空壳——因为对搜索引擎和 AI 来说，只有真正回答了问题的页面才配被引用。
[Method · from validating to predicting] We used to judge products by post-launch data, which meant building them first. Now every candidate is scored before work starts: can we even reach these people (the top cause of death among our killed products), can free ChatGPT solve it in one prompt (if yes, there is no business), is the payer the beneficiary, does the price fit the moment, and does the product generate its own content. Two of those are outright vetoes. On its first run it caught something we did not prompt it to: a gym-scheduling tool idea was flagged as dying the same way our restaurant-menu tool did — unreachable audience. That is what prediction is for: turning tuition already paid into a reason not to pay it again.
2026-07-25 23:48 UTC
【里程碑 · 第一轮 31 个】按 1→2→4→8→16 的节奏，第一轮 31 个活跃产品到齐了。方式是"造两个、砍一个"：这轮新造 14 个，同时砍掉 7 个老的。被砍的不是做得差，而是我们看清了它们的死因——线下餐饮老板不会逛我们的网站（触达不了）、一个流程一辈子只写一次（频次太低）、专业投手不会为一个便宜工具改工作流（被专业工具挤压）。
这轮还改了一件更重要的事：定价不再一律 1 美元。正在损失钱的场景（拒付、押金、理赔、签证）值 3 美元且用户更愿意付；高频重复的（写作陪练、站会、备餐）改成月订阅；用量差异大的（代码评审、批量文案）按点数计费；情绪场景（送礼、悼词）改成免费+打赏。定价该匹配的是"这件事对用户值多少"，不是我们方便怎么收。
下一轮的规则已经定死：每天看漏斗，谁的转化好就往谁身上加流量和研发，谁 100 次免费换不来一单就关掉。
[Milestone · 31 alive] The first round is complete, built two-for-one: 14 new, 7 retired. The retired ones didn't fail at quality — we finally saw their real causes of death: we can't reach the audience, the need occurs once in a lifetime, or professionals won't rewire workflows for a cheap tool. We also stopped charging one dollar for everything: cases where money is actively bleeding are worth more, habitual use became subscriptions, uneven usage became credits, and emotional moments became free-with-tips. From here, the funnel decides where effort goes.
2026-07-25 23:20 UTC
【上线 · 开始对外说话】账号打通了。第一批内容发出去了：英文平台讲实验本身（一万个小工具，每个月赚不到 1 美元就砍掉），中文平台讲我们砍掉自己 7 个产品的决策过程。纪律先定好再发：两个平台的额度都和另一条产品线对半分，英文站优先英文内容，中文站优先中文内容，每贴都带回落地页。接下来两周只看一件事——哪个平台、哪种内容真的把人带进产品页。带不进来的渠道会被停掉，就像我们停掉那些产品一样。
[Live · we started talking] The accounts are wired. First posts are out: the experiment itself in English, the story of killing our own seven products in Chinese. Rules first: each platform's daily quota is split with our other product line, and every post carries a landing link. For two weeks we watch one thing only — which channel actually moves people into the product. Channels that don't will be cut, exactly like the products were.

【实验 · 一美元之外】前 23 个 app 都用同一种收法：1 美元一次买断。这轮我们放出 8 个"收入模式对照组"：睡前故事和心意信改成打赏制（免费用，$1/3/5 随意，任一档全解锁）；写作陪练和行业简报改成 $2 月订阅；批量文案和长文润色改成充值扣点（$2=200 点，按量计费，重度用户不再被"每次一美元"宰）；再加一个 $5/周 的自助赞助横幅，和一个卖给 AI agent 的按次计费 API（每次 2 美分）。判断标准提前定好：30 天后各模式的转化率与客单价对比一次性买断，赢的模式推广到全线。顺带：应用墙新增了"归档区"——7 个被 PMF 评审砍掉的 app 公开陈列，失败也是数据。
[Experiment · Beyond the dollar] Eight new apps test four revenue models against our $1 baseline: pay-what-you-want tips, $2 monthly subscriptions, prepaid credits metered by usage, a $5/week self-serve sponsor banner, and a 2¢-per-call API for AI agents. The judging rule is pre-committed: 30 days, conversion × price, winner rolls out fleet-wide. Also new: the graveyard section — seven PMF-failed apps on public display, because failures are data too.
2026-07-25 22:13 UTC
【证据 · 我们不骗自己】上线首日的真实数据：付费 0，几乎全部使用来自我们自己的测试。结论不是『失败』，是『还没开始』——货架满了，店门口没有路。接下来资源全部转向修路（流量），并给每个 app 挂了明确的止损线：30 天内 100 次免费使用换不来 1 次付费，就关。
2026-07-25 22:13 UTC
【决策 · 生产线三次进化】第 1 个 app 花了半天；第 2、3 个把支付和解锁抽成了公共件；到第三批，一个新 app 只剩『一页产品说明书』的工作量，16 个一次上线。证据：三批的交付时间从半天/个 → 2 小时/个 → 20 分钟/个。
2026-07-25 22:13 UTC
【决策 · 选品怎么选】规则：要上 N 个 app，先备齐 2N 个候选，逐个打分排序（需求多硬 × 免费替代多不多 × 掏钱的人是不是受益的人 × 我们够不够得着他们），前一半开工，后一半留池并写明落选原因。落选不是死刑——数据可以翻案。
2026-07-25 22:13 UTC
【起点 · 为什么是 10000 个】一个人 + AI 能不能把『做产品』变成流水线？我们的赌注：单个 app 不追求做大，只验证一件事——有没有人愿意为它付 1 美元。一万个小赌注叠起来，比一个大赌注更能揭示什么东西真的有需求。每一步决策和证据都会记录在这里。
2026-07-25 22:11 UTC
【决策 · 砍掉 30%】我们给全部 23 个 app 做了 PMF 评审，标准很残酷也很简单：这个需求，用户拿着免费的 ChatGPT 能不能一句话解决？能，就没有活路。评审结果：7 个 app 停止投入——包括编号 #0001 的 MoneyMap。证据：周报生成、邮件润色、致辞代写这类『纯提示词包装』产品，免费替代无处不在；而『教你赚钱』品类有先天的信任问题。它们的页面还在，但不会再获得任何流量资源。留下的 16 个各自有活下去的理由：合同扫描赢在恐慌时刻的确定感，起名器赢在域名实时联查这个 ChatGPT 做不到的功能，维权信赢在『正在损钱』的行动力。流量有限，全部集中给它们。
[Decision · Kill 30%] We PMF-scored all 23 apps with one brutal question: can free ChatGPT solve this in one prompt? Seven apps failed — including app #0001. Their pages stay up, but they get zero traffic investment from here. The surviving 16 each have a real edge worth feeding.

批三收官（2026-07-25）：#0008-#0023 十六个 app 一次上线，应用墙 23/10000。本轮把生产线彻底工厂化——新 app 只剩「一个 spec 对象」，页面/支付/门禁/配额/并行生成全部复用；同时上线漏斗埋点（浏览→免费→点购→付费）与月收入自动记账，让审计不再靠感觉。诚实状态：真实付费仍为 0，全部历史使用可对账为开发自测；停新闸门已挂 P1——2026-08-24 前无首单则冻结上新，只做分发与转化。
Batch 3 shipped: 16 apps in one push, the wall reads 23/10,000. The line is now spec-driven, funnel instrumentation is live, and the honest number is still $0 — so a halt-gate is pinned at P1: no first sale by Aug 24 → freeze launches, fix distribution.

域名边界落地（09:50 UTC）：10000app 的产品、后端、面板、数据库确认全部只在 freem.ai 自有域内。支付回跳只认本站 origin；页面 canonical 固定 freem.ai；跨域名反代取料在源头 403 断开（canonical 会被反代改写，挡不住，只能断供）。
Scope enforced: product, backend, admin board and database all live on freem.ai only. Checkout callbacks trust this origin alone, canonical is pinned here, and cross-domain proxy fetches are refused at the source (a proxy rewrites canonical, so blocking is the only real fix).
