Building LLMTracker — a pay-as-you-go AI citation tracker (feedback welcome)

Working on LLMTracker — a pay-as-you-go tool that tracks how brands get cited by ChatGPT, Perplexity, and Copilot, plus a content audit to help figure out why a page might not be getting picked up.

Planning to launch here soon. Curious if anyone's tried other AI-visibility/GEO tools — what worked, what didn't, what you wish existed? Trying to make sure this actually solves a real problem before I put more into it.
