We put the 14 questions a person in Guildford asks before choosing architect — cost, specialism, who to use, how to check them — to Claude and ChatGPT, 5 times each, 140 answers in all, and recorded every firm the answers named. 30 firms in Guildford were checked against those answers. 8 of them were named at least once. The rest were not recommended in a single answer.

Firms are ranked by the number of answers that named them, then by how many different questions. The assistants do not give identical answers twice, so a difference of one or two mentions is noise; being named on questions a rival is absent from is not.
Every firm above has a private report: which answers named it, which rivals were named instead, whether its website can be read by the assistants, and the three things that would change the result. We work with one architect in Guildford, and this index is re-measured every month, so the change is visible here.
