How the board is made
Each run asks an AI assistant the question a customer would ask, "Who is the best electrician in Thousand Oaks?", with web search on, for every trade and every area on the board. The assistant is named on every page, the date is printed, and every answer is kept: a new run adds a new record and never edits an old one. Latest run: November 1, 2026.
Being named here is the assistant's answer, not Digilu's endorsement. Businesses are named only as the assistant named them.
