Asked for lawyers in Lyon, ChatGPT, Claude and Gemini most often named Fidal (31% of answers), CMS Francis Lefebvre (22%) and DELSOL Avocats (22%). Across 36 answers they named 65 different businesses, 40 of them only once. Each of four buyer questions was asked three times, in French, in September 2026.

The ranking

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.

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.
