We asked ChatGPT and Gemini 50 questions about Harvey

The legal AI giant dominates globally — but disappears entirely in key regional markets.

Harvey has become synonymous with AI for law firms. But when AI assistants field buyer-intent questions about legal tech, does Harvey actually get named — or do rivals steal the slot?

We ran 50 distinct questions across ChatGPT (web search) and Google Gemini (grounded). Different personas, different triggers, different geographies. No two questions share the same combination of axes.
