Which GTA home builders do AI assistants recommend?

Provisional reading. ChatGPT, Gemini and Google AI Mode answered the same 16 buyer questions three times, 3–5 November 2026. The ranking is final after the human check of builder-name matching.

3 runs · 3 AI assistants · 144 answers · How we measured

All three runs captured · provisional. Captured 3, 4 and 5 November 2026 (UTC) through SearchAtlas, Canada, with the same 16 questions. The numbers stay provisional until the human check of builder-name matching is done. An outage at the capture service's Copilot provider began on 3 November (11:45 UTC), so the score uses ChatGPT, Gemini and Google AI Mode; Copilot's run 1, captured before the outage, is shown separately below.

The ranking

Share is the position-weighted share of answers that recommend the business, 0 to 100, across every scored question, assistant and run in the reading. Spread is the variation between runs. Engines shows which of the scored assistants named the business at least once.

Provisional reading, captured 3–5 November 2026 (UTC): 16 questions × 3 assistants × 3 runs = 144 scored answers. Share = position-weighted mentions across the 144 scored answers, 0 to 100 (method §5, DCG weights). Spread = the standard deviation of the three per-run shares (method §5). Engines = which of ChatGPT, Gemini and Google AI Mode (AI Mode) named the builder at least once. Runs named = in how many of the three runs any of them named it.
