How this list is built
GeoGenius asks ChatGPT, Claude, Gemini and Grok the questions a buyer or seller would ask about Portland, ME and records every agent each engine names. A person is listed once at least two responses, or two different engines, have named them; their brokerage, as the engines state it, is resolved to its core brand. The method mirrors our published 36-market study at https://geogenius.ai/ai-report.
