The first Dual Web demo. You need to see this. One site. Two experiences. Human visitors get UX. AI agents get answers. This changes everything. @ycombinator

Why are you not talking to AI like this?

am I the only one who doesn't see much of a difference between gpt-4o and gpt-5? kinda disappointed

I didn’t code it. I didn’t design it. I just figured out what would make people click. And when they did, the whole funnel lit up. That’s my version of build in public.

Posted a Loom to a cold lead at 11:47 PM. Didn’t expect anything. Next morning: “Just upgraded to Pro. This is exactly what we need.” Don’t overthink the hour. Send the damn Loom.

I almost scrapped the whole thing. Two weeks ago I looked at what we’d built and thought: “This isn’t working. Nobody gets it.” But instead of quitting, I started talking to users again. One of them said something that changed everything: “Wait... so this shows how often AI mentions my brand? That’s gold.” Boom. Clarity. We stopped overexplaining. Rebuilt the pitch. Focused on what actually matters to the people we serve. Now we’re getting signups daily. Build in public means building through confusion, not around it.
