Mo's verdictExample

Try a different angle

Commuters do want lessons they can just listen to, but a broad “learn Mandarin” app is crowded: at least six already sell it for CA$10–17 a month. Two-way audio albums for the commute are open.

林梅用一句话说出点子，Mo 把它整理成一张能直接改的点子卡。

不只是一个模型， 而是一支做过这件事的团队。

01

靠经验，不靠猜。

每一步都照真实产品团队的经验来：先做什么、测什么、审核会卡在哪里。

常见 AI 产出

常见 AI 产出Molby
同一个点子：一句提示词，还是一支做过的团队。
02

每件活，用对的模型。

简单的活用快模型，要判断的地方用最强的模型，做完都再查一遍。你为结果付钱，不为重试付钱。

03

上线之后，还在。

上线只是开始。Mo 帮你盯着数据，告诉你下一步先修什么，也帮你找到第一批用户。

认识一下团队。

Mo 带队，每位专家负责一个阶段。

  • Mo带队。你只需要跟它说话。在等你
  • 研究员值不值得做？忙着
  • 设计师让它看起来够专业。忙着
  • 用户研究员找真人来试。忙着
  • 工程与测试做出来，再测一遍。忙着
  • 上线把它送上线。忙着
  • 分析师帮它成长。忙着

点任意一位，看看他在忙、做完了，还是在等你。

三个人，三个真实的需求。

每一个都已上线。可以直接打开，也可以看看是怎么做出来的。

常见问题

我需要会写代码吗？
不需要。你跟 Mo 说，看团队做出来的东西，然后拍板。你不会碰到代码，也不用挑 AI 模型。
能做些什么？
先从网站和网页应用开始：个人网站、预约或会员网站、课程、小店、小工具。iPhone 和 Android App 随后推出，用同一个项目来做。
产品和收入归谁？
归你。产品用你的名字和你的账号上线：你的域名，你的 App Store 和 Google Play 开发者账号，你的收款账户。用户和钱都是你的。
和 Lovable、Bolt 有什么不一样？
那些是要你自己一步步指挥的 AI 工具。Molby 是一支团队：先告诉你点子值不值得做，再设计、找真人试用、开发、上线、陪你成长，每一步都自己检查。
为什么不直接用 ChatGPT 或 Claude？
它们很会回答问题。但拥有一个产品，要按对的顺序做几百个决定，要上线，上线后还要照看好几个月。Molby 用的就是这些模型，每一步挑最合适的那个，放进一套来自真实产品经验的流程里。
怎么收费？
Mo 每次开工前，你都会先看到能拿到什么、要花多少，你确认的价格就是最终价格。交付的东西和你确认的不一致，Mo 免费重做。改主意算新的需求。内测价格会随邀请一起发给你。
我的点子会保密吗？
会。你的点子和项目都是私密的。我们不会分享，也不会拿来训练 AI。
