How clearly can the AI era see you?
— The Signal Index
A free, reproducible 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.
— What the score means
One number, four places you can stand.
0–39
Invisible
The machines don't know you exist.
40–64
Emerging
Findable by name; weak in AI answers.
65–84
Visible
You show up, with real authority.
85–100
Dominant
The answer AI keeps giving.
