How to read this chart
How to read: each dot is one snapshot. The green line is where this firm ranked among peers on that day. The dashed amber line is the mention rate — the share of AI responses in that snapshot that named this firm at all.
Rank and mention rate use different scales, so the two lines are placed side-by-side, not on top of each other. A firm can hold rank while mention rate drifts (fewer responses named anyone) or improve rank without moving mention rate (peers dropped out).

Buyer questions and AI answers
Simulated buyer questions from Atlas’s test dataset, paired with AI answers that mentioned this firm or professional. Open to see the questions and what was said.
95 AI answers with recorded context · 0 reviewed in context
Atlas asks AI assistants questions written from the perspective of people seeking services in a particular city and situation. Each example connects a simulated buyer question to an answer that named this firm or professional. A name can appear as a recommendation, a related adviser, a comparison, or even an option the assistant advises against.
A mention does not verify services, eligibility or suitability. Context review explains how the name was used; it does not verify the assistant’s claims. Explore the test questions and methodology.
