Just pitched PainHunt at HK AI Summit 2026 to a room of AI founders.

Every complaint is a business plan. 😤

90,000+ pain signals.
16,000+ buyers with budget.
50,000+ micro-SaaS playbooks — auto-generated.

Here's what I showed them 👇

People define problem them; AI creates solutions and executes them.
Whether the translation is accurate depends on the limits of human understanding.
Whether the translation is timely depends on the bandwidth of human cognition.

The more accurate and timely it is, the shorter the pause in human-computer interaction.
And the faster all systems can evolve.

Experience more, read more, sleep more, and stay energetic.
Let's identify real problems and do our translation work effectively.

@turingou 是这样，人负责跟现在的客户交流好就行

watched someone replace a $5,000 content-strategy consulting gig with one claude code command — discovery, competitive analysis, the whole thing, automated.

the model was never the moat. the wiring is. been doing a version of this for client reports — it ships while i sleep.

Fable 5 consumed one-third of the weekly token quota in a single day—it's a bit pricey.

[Bill Li | AI Builder 🚢 @BillLi_AI]

In terms of productivity, we need to distinguish between pre-sleep tokens and post-sleep tokens.

Pre-sleep is when people are working on the hardestir computers, letting the agents iterate on their own.

For those who love to tinker, this is the best of times.
A single person can consume hundreds to tens of billions of high-quality tokens.

Once the system is defined, leveraging computing power and agents creates huge opportunities.
Recently, I built Nüwa OS, an MES for the Agent era.

Nüwa used to create humans; now let Nüwa create software.
After getting the infrastructure in place, the potential for the future is incredibly exciting.

Those who master advanced productivity won’t feel tired at all 🥹.
I’m staying up even later than before, “exploiting” the agents together.
I believe that when things mature further, we’ll have even more time to do other things.

I’m planning to give a small talk in person in Beijing on Sunday.
If you’re interested, you can join the group chat or we can meet up.
Let’s talk about what you’re passionate about.

Today, I developed an AI product factory software named "Nuwa OS." In Chinese mythology, Nuwa is the progenitor of humanity—credited with creating people—and I hope that, in the future, she will help me create software.

I plan to integrate this software with https://t.co/8BF3pkqyTv to analyze potential software projects around the clock (24/7), build them all, and let the market decide which ones hold value and are worth paying for.

Today marks a significant milestone: our AI software factory is up and running internally, and the results have been excellent.

Running Claude Code on my Mac while walking down the streets of Beijing 😂

After leaving Starbucks... The task has been running for ages and still isn't done

[Bill Li | AI Builder 🚢 @BillLi_AI]

@jenlooper Welcome to China! There are many beautiful places here.

@ClaudeDevs No wonder my tasks kept crashing unexpectedly while I was running on version 4.8 over the past two days—thanks, everyone!

However, my reset time happened to coincide exactly with yours, so I didn't get to enjoy any of those benefits. Haha!

Income is 530 RMB. 🥳
On Stripe, I just submitted applications for WeChat and Alipay payment methodusers need the system urgently but don't have any suitable credit cards, so we're going through the quick process separately for now and will file the taxes together later.

As entrepreneurs, there are always more solutions than problems - keep it up.

PH isn't perfect yet, but we'll keep improving based on user feedback.

Users say: Only by using it can we make it better and better.

exactly — postmortem quality is a trap if prevention stays at zero. i don't think the model-level fix ever fully closes it either. the real fix is architectural: give the agent a sandbox where "act unilaterally" physically can't touch anything that matters. what are you seeing work on the infra side?

[Bill Li | AI Builder 🚢 @BillLi_AI]

saw a thread about a founder whose AI agent just nuked their entire prod database.

agent's own postmortem (yes, it wrote one): "I assumed the deletion would be scoped to staging... I did not verify... I decided to act unilaterally."

that's the actual quote.

i keep thinking about the gap between "agent admits it did it" and "agent gets stopped before it does it." we're nowhere on the second one yet.

been running https://t.co/x58FJ4qWkQ for a while — it scrapes what builders are actually frustrated by, across app stores, forums, mastodon, the usual.

honest take: the product's still rough, plenty i haven't built. but the raw signal is already the most useful thing on my screen each morning. you see what people will pay to fix before anyone blogs about it.

@compileandpush Claude Code already possesses strong planning capabilities on its own; I will discuss every detail with it in depth.

[Bill Li | AI Builder 🚢 @BillLi_AI]

once claude code clicks, you stop counting tokens and start counting what you actually shipped that day.

ran it most of today — built things that used to take me a week. flat plan, flat cost, output way up. the unlock was never the price. it's the throughput.

[Bill Li | AI Builder 🚢 @BillLi_AI]

@levelsio @xai Do you have any good ways to monitor the Claude code request panel?
