The three ideas in the video

01 · THE MECHANISM

A buyer's question is never searched as written. Google's AI rewrites it into several searches of its own, reads what ranks for those, and names agents from the pages it read.

02 · THE GAP

Elmo shows the end of that chain: who got named, what got cited. The middle step, the searches, holds zero real queries for Parallax today.

03 · THE PROBE

Google's Gemini API with Search grounding returns the searches it typed and the pages it read. On DishwasherFit this morning: 118 questions, 207 hidden searches, cited on 12.

One limit, stated in the video: it is a proxy for Google AI Mode, and Maps and Business Profile cards stay out of view. Still, it is the only window we have on the middle step.
