Real questions, asked the way customers ask, with no business name inside any question. Every named business below appeared in an actual AI answer, saved and dated.

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.
