What ChatGPT, Gemini and the other AIs recommend in Brussels, in all three languages

I asked 7 AIs (ChatGPT, Claude, Gemini, Perplexity, Grok, Mistral, Muse Spark) 8 identical buyer questions from the Presence angle, for 5 professions in Brussels.

Each question twice: first without web search, then with web search (Perplexity only answers with web search). And in each language of the city.

Here are the businesses they name.

Measured on 29 October 2026, one month after the first measurement (24 September; 30 September for Montréal).

These are the AIs’ answers, not a quality ranking. A business missing from these lists can be excellent. That is exactly the problem.

Frequently asked questions

Does ChatGPT name my business in Brussels?

Not necessarily. Across the 5 professions measured in Brussels, most businesses are not named in any answer. Those that are change with the language of the question. The Snapshot measures your business in your language and your city.

Why do the answers change with the language?

The AIs search different sources depending on the language: directories, media, websites. In Brussels, the sources cited in French, Dutch and English are not the same. A business visible in one language can be missing in the other.

Which AIs are measured?

ChatGPT, Claude, Gemini, Grok, Perplexity and the other AIs of the panel, with and without web search, with 8 identical buyer questions for each profession.

Are these figures a quality ranking?

No. They are the AIs’ answers, measured on a given day. A business that is missing can be excellent. That is exactly the problem.

How do I get my business, or a client’s, measured?

The Snapshot: two targets (two languages, two cities or two personas), the full report with the actions and their proofs, and the second measurement 30 days later. See the Snapshot

Are you an agency?

Measure one of your clients in their city and their language.

$250, report in 48 hours.

Your business is not listed?

Leave your name and your city.

I put you in touch with a partner agency or consultant who measures and corrects your visibility in the AIs.
