Law firms in Paris & Lyon, as the AIs see them

When someone asks Gemini, Meta AI or Perplexity "the best lawyer for my problem," a handful of firms capture the recommendations. Here is who dominates each practice area, who stays invisible, and where the untouched territories hide — query by query.

01 — KEY FINDINGS

What the AIs actually say about the market

Six structural truths emerge from 80 real-world legal queries cross-checked on 3 AI engines (240 answers, 640 citations).

02 — RANKING

The AI Visibility ranking (KVS)

The KAIS Visibility Score measures each firm's probability of being recommended by an AI — weighted by citation rank and multi-engine coverage. Normalized to 100 per city. Filter by city.

■ Gold bar = the city's absolute leader (KVS 100) KVS normalized per city and practice area — panel: Gemini · Meta AI · Perplexity
03 — THE 3-ENGINE RULE

One engine isn't enough: three behaviors, three audiences

The three engines name neither the same number of firms nor the same ones. A firm can be perfectly visible on Gemini and absent from Meta AI for the same question. Optimizing for a single engine caps your visibility.

The cost wall:

04 — BY PRACTICE AREA

Who owns the answer, area by area

The hierarchy changes radically from one practice area to the next — and from one city to the other. The Reference Rate is the share of answers that name at least one firm in the area.

05 — ATTACK MAP

Money queries, blue oceans & ghost queries

Three distinct commercial territories: the practice-area × city pairs locked by an incumbent, those still fragmented, and the queries where no firm is recommended at all — the purest content opportunity in the sector.

Fine per-query read: ranking of cited firms and their position on the Gemini + Meta AI text panel (Perplexity folded into the aggregate KVS). "Locked" = a firm cited at the top recurrently in the area. "Fragmented" = leader present on a single engine.
