How this page is made

How this page is made: we ask 3 real customer questions across 5 AI engines: ChatGPT, Gemini, Perplexity, Claude, and Google AI. Google AI is measured on 2 surfaces, AI Overviews and AI Mode, so 5 engines make 6 measured surfaces. A business is NAMED only when its name appears in the machine's actual answer text. Hinted at or linked does not count. Answers are saved word for word, dated, and content-hashed. No business name is ever inside a question, so no result can be nudged. Paying us never changes what the receipts say. This page is a set of dated observations: AI answers vary between runs.
