AI Visibility Index · November 2026

Asked about interior designers in Cardiff, ChatGPT, Claude and Gemini named Studio Severn most often, in 19% of answers (its AI Recommendation Rate), then Jeffreys Interiors (14%) and The Interior Design Practice (11%). Across 36 answers they named 68 different businesses, 49 of them only once. Each of four buyer questions was asked three times, in English, 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 interior designers in Cardiff

How AI assistants recommend interior designers

ChatGPT, Claude and Gemini named Studio Severn most often, in 19% of 36 answers, then Jeffreys Interiors (14%) and The Interior Design Practice (11%). 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 Studio Severn most often (50% of its answers), Claude Hayburn & Co (25%) and Gemini Jeffreys Interiors (42%). 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, 17% 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 interior designers, 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 interior designers 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.

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.
