AI Visibility Index · November 2026

Asked about plumbers in Montreal, ChatGPT, Claude and Gemini named Plomberie Roger Chayer most often, in 33% of answers (its AI Recommendation Rate), then Plomberie Montréal (31%) and Plomberie SOS (17%). Across 36 answers they named 78 different businesses, 59 of them only once. Each of four buyer questions was asked three times, in French, in November 2026.

The AI Recommendation Rate is the fraction of the 36 answers that named a business. The range under it is a 95% confidence interval: where two ranges overlap, the gap between those businesses could be chance.

Names are printed as the assistants wrote them. We have not checked that any of them is good, open, or real.

Questions about plumbers in Montreal

How AI assistants recommend plumbers

ChatGPT, Claude and Gemini named Plomberie Roger Chayer most often, in 33% of 36 answers, then Plomberie Montréal (31%) and Plomberie SOS (17%). The names come from what the assistants answered to four buyer questions in November 2026; we have not checked that any of them is good, open or real.

Not always. ChatGPT named Plomberie Ren-Ga most often (50% of its answers), Claude Groupe Master (33%) and Gemini Plomberie Montréal (92%). 3 of the 19 listed businesses were named by two or more of them.

Each question was asked three times. Of the names an assistant gave for a question, 26% came back in two or more of those runs; the rest came up once. The 95% range beside each rate in the ranking shows how far it could move by chance.

Run the free checker: it asks ChatGPT, Claude, Gemini and Grok two of the Index questions for plumbers, with the category and the place already filled in, and shows every answer word for word. About 30 seconds, no sign-up. The page on how AI assistants recommend plumbers shows what an owner can work on. Nothing can guarantee that an assistant names you.

Every business in the ranking was named in two or more answers. The badge says that and nothing more: no position, because the ranges above do not support one. It links back to this page, so anyone can check.

The questions

Asked word for word, three times each, to every assistant, in French. The English under each is our translation. The prompt is the one the free scan uses. No web search, no location and no chat history, so every answer starts from the same place.

How to read this page

The full method

What it measures: Which names these models produce when asked cold, from what they learned in training. It is not a review, a rating or our recommendation, and a business missing here may simply be one the models were never shown.
Why the ranges matter: 36 answers is a sample. Asked again next month, most shares will move by a few points; the ranges say how far they could move by chance alone.
One business, several spellings: Branches, legal suffixes and spellings of one business are merged, and the other spellings are printed under its name. Names that might be two businesses are kept apart.
A name is wrong: If a business here is closed, misnamed or yours and you want it removed, tell us. We correct or remove it when the page is next published.
