28 days. 22 local US markets. 4 AI assistants + Google SERP. Which businesses the machines named, counted, dated, and published.
Every day in September 2026, NameBeam asked the same buyer-intent questions (“best [service] in [city]”-style local queries) to ChatGPT, Claude, Perplexity, and Gemini, with Google SERP as a baseline, across 22 local US markets. Every answer was saved with a date. The metric: distinct local businesses each engine named per market, summed across September 1 to 28.
| Engine | Businesses named per niche-market |
|---|---|
| Gemini | 21.2 |
| OpenAI (ChatGPT) | 18.7 |
| Perplexity | 17.8 |
| Google SERP (baseline) | 13.7 |
| Anthropic (Claude) | 1.5 |
Normalized per niche-market, raw totals mislead because markets track different niche counts (Pleasanton 8, Los Angeles 1). We published the correction against our own first headline: see the recap.
Journalists: the corpus is the credibility, the businesses are the hook. Interview, per-market data, and the full 179-business Perplexity-only list on request.
Corpus: September 1 to 28, 2026 (not every engine answered with names every day), 22 local US markets (21 metros + 1 nationwide query set).
Systems tested: ChatGPT (OpenAI), Claude (Anthropic), Perplexity, Gemini (Google), plus Google SERP as a non-AI baseline.
Metric: distinct local businesses named per engine per market, summed across run days. Answers change over time; no rankings are promised.
Transparency: per-market reports are public and dated. NameBeam tests on itself first, in public, at proof.namebeam.ai.
NameBeam, operated by Carter Enterprise LLC, runs a free 5-engine AI visibility check for local businesses, ChatGPT, Claude, Perplexity, Gemini, and Google AI, with dated transcripts. Motto: “Every claim owes the future a receipt.”
