What it means for plumbing companies in Houston
A buyer who asks an assistant for a recommendation gets a short list of names. Across all 192 answers, the five firms above took 269 of the 827 recommendations; the other 137 named firms shared the remaining 558.
The assistants also disagree. 110 of the 142 firms were named by just one of them, so a firm that comes up in ChatGPT can be missing from Claude or Gemini. Checking one assistant tells you little about the rest.
How we tested
On October 22, 2026 we put the same 48 questions to ChatGPT, Claude, Gemini and Perplexity, worded the way buyers ask, from “best plumbers in Houston” to questions comparing firms. We stored all 192 answers word for word and counted every firm each one named. One run is a snapshot; answers shift between sessions, which is why we re-check weekly for clients. Full details are on our methodology page.
