What SEO professionals say

The combination of technical SEO + GEO for AIs is unique. Now I can see at a glance if my content will be cited by ChatGPT or Perplexity. The Citability Score is pure gold.

SM
Sarah Mitchell SEO Specialist · Digital Agency

The competitor comparison saves me 2 hours per audit. Before I had to open 5 tabs and copy data manually. Now I have everything in one table ready to present to the client.

JA
James Anderson Freelance SEO Consultant

The Anti-AI detector is brutal. It has helped me rewrite content that seemed too robotic and was penalizing engagement. An essential tool in 2026.
