Dentists in Rotterdam: which clinics ChatGPT and Gemini name
Loef Mondzorg only comes up once ChatGPT or Gemini searches the web. From the models' own memory it appeared in 0 of 36 answers, and with a search it appeared in 15 of 24. The other clinics followed the same path, and only Gemini brought them in: Parla House of Dentistry in 5 of 30 answers and Mondfit Mondzorg in 4 of 30, while ChatGPT never mentioned either.
None of the clinics on the list came up when someone needed help with an urgent toothache, wanted implants or was watching a tight budget. Across all the answers, other names appeared far more often. Erasmus MC was named in 30 of 60 answers, and Tandarts West and Lassus Tandartsen were each named in 21 of 60.

How Rotterdam was measured
Each of the 18 questions went to ChatGPT and to Gemini; 12 of them were asked twice, with the model's web search off and on. A question that itself named a clinic is left out, since its answer would name that clinic by force. The clinics we tracked are the ones we chose to measure in Rotterdam and the clinics they compete with for the same patients.
Ansmeter Benchmark v2.0, methodology 2026.10, prompt library 2026.10-service-voice. The method and its limits: Methodology. The table as a file: data.csv.
We ran this measurement on our own initiative; no clinic asked for it or paid for it. If a clinic's name or website is wrong here, write to us and we will correct it.
