You know the feeling. You describe an idea to an AI builder and it comes back with something that technically works. And your first reaction is.. that's cool, but that's kind of "not it". By the time you notice, you've already spent a ton of tokens.. Both on the look and feel, and on everything underneath it, the database, the schema, the routes you didn't even know you'd need yet. I've been burned by this enough times to now do something different. I'm working on a new feature for Funnel Pulse right now. It maps the entire customer journey past the funnel. Abandoned cart, purchase, delivery, onboarding, all of it, tied together with webhooks so you always know where every one of your people actually is. I haven't seen anything like it in our world. Which is exactly what made it hard to picture. I was working it out with an LLM and at first it was just pages of text. Then we moved to ASCII drawings, boxes and arrows, trying to get some shape around the idea. At one point I had it render actual UI cards, just so I could get a feel for it. I still couldn't tell if we were circling something valuable, or something confusing, or something unfocused. So I changed the approach. The fix is dead simple, even when the feature isn't: Build the fake version first! Make it look and feel completely real, and don't touch a real database or app plumbing until you actually know what you're building. Here's what that looked like for me this week. Instead of having the LLM build this inside Funnel Pulse itself, I had it take the existing product's look and feel .. the actual design language .. and build one static HTML file. Fake screens. Hardcoded fake data. Simulated clicks that show and hide different states as you click through the workflow. Nothing real underneath it, no database, no backend, no schema. I've been in that file for hours today. Wired up a fake webhook from Kajabi, and watched it light up a milestone on the map. I even added a little wobble animation on the connection. An homage to Propellerhead Reason, if you know it .. patch cables are basically what this whole thing is built on.
