I built a tool to check if ChatGPT recommends your business, and found a genuinely interesting LLM quirk along the way

The idea

I kept running into the same thing while researching AI visibility tools. Agencies have basically no idea whether ChatGPT even knows they exist, let alone whether it would recommend them over a competitor. So I built a small tool that asks ChatGPT the way a real prospect actually would, shows you the raw answer, and tells you who got mentioned ahead of you.

Stack is Next.js with the App Router, Supabase for storage, the OpenAI API for the actual audit calls, Tailwind for styling, deployed on Vercel.

The interesting part

While testing it I ran it against Mother, a real, well known independent ad agency founded in 1996. I asked two versions of basically the same question.
