Performance marketer · builds his own tools

I build AI tools that do real marketing work.

Not prompt screenshots — working tools, solving problems I actually hit as a marketer: getting recommended by AI engines, reading competitors’ winning creative, and finding the one fact that qualifies a lead. Every result here is real. Where a demo is cached or a method has limits, it says so.

How I think about it

The build is the easy part. The judgment is the point.

Anyone can paste a prompt into ChatGPT. The value in each of these is a marketing decision: which questions a buyer actually asks, why a surviving ad is a better signal than a clever one, which single field turns a name into a qualified lead.

They’re also built to distrust their own output. AI is a confident, unreliable pattern-spotter, so every tool here verifies the model instead of trusting it — reporting frequency instead of a single yes/no, throwing out answers it can’t prove against the source, and telling you where it’s weak.

A tool that’s honest about its limits is worth more than one that sounds impressive. That’s the whole thesis of this page.
