Building growResonance, open source

About

I'm Lucas, founder of growResonance 👋 More and more people ask AI models instead of Google, and the answer decides which brands they see and trust. I'm building an open source tool that shows companies what AI says about them and how to improve it, without enterprise pricing. Into AI search, GEO, open source and building in public. Always happy to talk about how AI picks its answers. 🔗 growresonance.ai ⭐ github.com/Lucasw0427/growResonance.ai_open

Query fan-out: the hidden searches behind every AI answer

When someone asks ChatGPT or Google AI Mode a question, the AI usually doesn't search for that exact question.

That changes how brands get found in AI answers.

How do you check what AI models say about your brand, and how do you improve it?

More and more people ask AI models instead of Google: "best agency near me", "which CRM for a small team", "is X worth it". The answer decides which brands they see and trust.

We're launching growResonance tomorrow: an open source tool that shows how AI models talk about your brand, where you rank against competitors and what to do to improve.

Before we go live, I'm curious:
