Shipping Hook Machine in about three days

Hook Machine started as a straightforward question: could I ship a genuinely useful marketing tool fast enough to film the whole thing? The premise is simple — you give it your website once, it builds a permanent Business Brain, and from then on it generates hooks that sound like your business instead of generic AI slop.

I also used the build as a real comparison. Not a benchmark on a slide — an actual product, built by different coding agents, where the difference shows up as works in the demo versus survives a real user.

What actually happened

The first agent was fast. Within a day I had something that demoed beautifully: type a URL, get hooks, feel clever. That's the part that films well.

Then reality showed up. Edge cases. State that didn't persist the way the Business Brain needed. The confident-but-wrong changes where a model rewrites something that already worked. Getting from great demo to I'd let a stranger use this took a second agent and a lot of unglamorous hardening.

What the build itself did

The build got documented across eight short videos that pulled roughly eleven thousand views — my first real signal that showing the work is as interesting to people as the tool itself. That's the thesis this whole site runs on.

What I'd do differently

• Define done before the first agent starts — production criteria, not demo criteria.
• Treat the second agent's hardening pass as planned work, not a surprise.
• Capture the boring failures on camera too. The bugs are the interesting part.
