Plumbers in Los Angeles, CA: who AI recommends

When someone in Los Angeles asks an AI assistant for a plumber, the answer is a shortlist — and being off it means never being considered. This page tracks that shortlist: the same consumer questions go to ChatGPT, Claude, Gemini, Perplexity and 8 more AI assistants every week, and what they answer is recorded here.

Covers Los Angeles and nearby areas including Long Beach, Glendale, Pasadena, Santa Monica, Burbank.

Where this ranking stands

This cell is recording. The same 3 questions below go to ChatGPT, Claude, Gemini, Perplexity and 8 more AI assistants on a weekly cadence, and every answer is kept — nothing is published until enough independent runs accumulate to clear our sample floor. A thin sample would make a noisy answer look authoritative, so an honest "still recording" beats an invented top ten.

Rankings summarize what the AI assistants answered on a fixed, unbranded question set — they are measurements of AI output, not AI Syndicate's endorsement of any business. Placement cannot be bought. Full detail in the methodology.
