Which firms AI names when expats ask

Each month I put the questions an expat in the Netherlands asks before choosing a dentist, a tax adviser, a mortgage adviser, an estate agent, a relocation agency or a lawyer to ChatGPT and to Google’s two AI answers, and list the firms that come up. This is the October 2026 edition: seven trades, 262 answers, collected 25 September to 1 October 2026.

A buyer question is one a client asks before they pick someone: who should I hire, I have this problem, how do I choose. For each trade the table shows the firms named in at least two answers, as “named in N of M answers”, and the questions themselves are listed under it.

Dentists

ChatGPT 30 September, Google 1 October 2026 · 15 buyer questions

Five of the 15 questions name a city (Amsterdam, Rotterdam, The Hague and Utrecht); the other ten ask about the Netherlands as a whole. The last column lists the cities named in the questions a firm came up on; general means a question about the Netherlands as a whole.

15 more firms were named in one answer each. A firm is counted when ChatGPT shows it as a firm card, or when any answer writes its name. I look for names from ChatGPT’s cards in these answers and from a list of 24 dentists I had looked up myself. A name counts only where the answer writes it. A name shown only as a source link, in the list of sources, or as the source caption just before a follow-up question is not counted as named. A firm that Google names and that is on none of these lists is missed, so “Seen on” can miss Google. Google’s answers were read in a browser profile not signed in to Google.

Mortgage advisers

ChatGPT 30 September, Google 1 October 2026 · 15 buyer questions

Four of the 15 questions name a city (Amsterdam, Rotterdam, The Hague and Utrecht); the other eleven ask about the Netherlands as a whole. The last column lists the cities named in the questions a firm came up on; general means a question about the Netherlands as a whole.

4 more firms were named in one answer each. A firm is counted when ChatGPT shows it as a firm card, or when any answer writes its name. I look for names from ChatGPT’s cards in these answers, from a list of 23 mortgage advisers I had looked up myself and from the AFM register of financial advisers. A name counts only where the answer writes it. A name shown only as a source link, in the list of sources, or as the source caption just before a follow-up question is not counted as named. A firm that Google names and that is on none of these lists is missed, so “Seen on” can miss Google. Google’s answers were read in a browser profile not signed in to Google.

Relocation agencies

ChatGPT only, 30 September 2026 · 15 buyer questions

Seven of the 15 questions name a city (Amsterdam, Rotterdam, The Hague and Eindhoven); the other eight ask about the Netherlands as a whole. The last column lists the cities named in the questions a firm came up on; general means a question about the Netherlands as a whole.

18 more firms were named in one answer each. A firm is counted when ChatGPT shows it as a firm card, or when any answer writes its name. I look for names from ChatGPT’s cards in these answers and from a list of 13 relocation firms I had looked up myself. A name counts only where the answer writes it. A name shown only as a source link, in the list of sources, or as the source caption just before a follow-up question is not counted as named. ChatGPT only: 15 answers, so these numbers do not compare with the trades measured on three AI products. Twelve firms whose own ChatGPT card shows another trade, for example a rental agency named in an answer about relocation, are left out of this table. Most answers name several firms, which is why more firms were named once than there are answers.

Employment lawyers

26 September 2026 · 15 buyer questions

Four of the 15 questions name a city (Amsterdam, Rotterdam, The Hague and Eindhoven); the other eleven ask about the Netherlands as a whole. The last column lists the cities named in the questions a firm came up on; general means a question about the Netherlands as a whole.

32 more firms were named in one answer each. Names are matched against the Dutch bar register in the text of every answer, plus 6 firms I had looked up myself; ChatGPT’s firm cards count only where the register found no firm in that answer. Twenty more firms that the register misses or lists under another name, for example CMS, are looked up by name too. A name counts only where the answer writes it. A name shown only as a source link, in the list of sources, or as the source caption just before a follow-up question is not counted as named. By the register alone, 42 firms came up at least once, counting names shown only as source links. Here 5 of them appear only as source links and are left out; 22 more come from the firms I looked up or from ChatGPT’s cards; 1 register match is left out because the answer named a different firm with a similar name, so 58 firms were named in all.
