Building with AI.
Thinking about products, users, growth, and what’s actually worth making.
Sharing what I test and learn along the way.

[Leon.li @leonli1994b3]

I've built a few small things with AI.

One of them made money. Most didn't.

The lesson wasn't “build more.”

It was that building is getting easier, while figuring out what people actually want is still hard.

So this account is where I'll think out loud about AI products, useful workflows, growth, and the problems people keep running into.

I'll share things I try, things that surprise me, what works, what doesn't, and whatever I end up building next.

I don't know what the next product will be yet.

That's part of why I'm here.

I want to get better at noticing real problems before rushing to build solutions for them.

I recently came across a pretty interesting project called Ctx.

It tackles a problem that has always been annoying in software development:

Git is great at telling you what changed, who changed it, and when.

But why a piece of code was changed that way usually lives in commit messages, PRs, docs, comments, or simply in the head of the person who wrote it.

Over time, that context is easy to lose.

AI coding gives us a different way to deal with this.

Tools like Claude Code and Codex leave behind full sessions as they work. Those sessions record what task they were given, what they looked at, what they tried, and what they eventually changed.

Ctx indexes those sessions.

So the next time you come across a piece of code changed by an AI agent, you don't have to guess why it was written that way. You can just pull up the original session.

@AndyHu44502446 晚上挂了耽搁自己事情，白天挂了可以摸鱼。

[Leon.li @leonli1994b3]

@MaxForAI 要是白天挂该多好啊，可以光明正大摸鱼。晚上挂只会耽搁自己的事情。

[Leon.li @leonli1994b3]

要是AI在白天挂掉该多好啊，可以光明正大的摸鱼。晚上挂只会耽搁自己的事情，哭死。

[Leon.li @leonli1994b3]

@_FORAB 已经成瘾了，没AI。啥事都干不了了。

[Leon.li @leonli1994b3]

看到有人发帖说ChatGPT挂了，我还没太注意。结果等我的挂了，居然第一时间怀疑网或者VPN有问题。哈哈哈

果然成瘾了，没GPT，啥都做不了。还我ChatGPT！！！

@Jack_FluxAI 羡慕极了

@0xqiubite 那个物价？我们2个人，不到300就吃的很撑了。当然毛肚是真尼玛贵

@qianyuwing 今天周四，先来个疯狂星期四。

Full investigation from Unit 42:

[Leon.li @leonli1994b3]

This is kind of brazen.

Unit 42 recently disclosed a ransomware attack.

The attacker used AI agents across multiple stages, from reconnaissance and credential hunting to lateral movement and persistence.

The report estimates that work that might normally take human operators around two weeks was completed in under 10 hours.

And even more brazen: after the attack, an 80-page security audit was left behind.

@eric20050906 也不知道咸鱼的靠谱不，估计是扔给ai改的吧。之前我做过一个检测内容是否是ai生成与改写的网站，但是我测过很多次，检测出来的结果不行，所以我就放弃了。感觉难度蛮大的。哈哈哈

[Leon.li @leonli1994b3]

@_FORAB 很多中国企业不都这副德行的吗，就该来一波整顿。

[Leon.li @leonli1994b3]

@eric20050906 哈哈，这应该是一个不错的需求。不过在实现上会比较难。

[Leon.li @leonli1994b3]

@MaxForAI 我觉得，很多人根本就没深入思考，觉得某个不错，就存下来了。而实际上可能并不需要。就像购物一样，买了一堆东西，然后很多就吃灰了。

[Leon.li @leonli1994b3]

@brucexu_eth 我觉得个人原因更大吧，年龄大了会求稳，并且路径依赖了。而年龄小的人的路还在探索中。

[Leon.li @leonli1994b3]

@aicume 甜食能使心情变好，哈哈

[Leon.li @leonli1994b3]

@GlobalLinkTrade 就是每天瞎几把乱想，又不去行动。

[Leon.li @leonli1994b3]

@tanzhengmc97 上班性价比极低。
