How clearly can the AI era see you?
The Signal Index
A free, transparent score of how AI and search find, understand, and recommend you. In two parts.
- Enter your domain for Part 1, free and instant. Your Foundation Score: can the machines reach, read and understand you.
- Add your email for Part 2, also free: how AI actually answers about you across ChatGPT & Perplexity. (Your email is only used to verify you and send the free report.)
- You get a scored report and a prioritised roadmap, and we fix what you'd rather not.
We make you legible, so you get chosen, not the loudest.
