What We Measure

Agreement Rate

What percentage of recommended businesses are cited by two or more AI platforms? Low agreement means AI recommendations are inconsistent — the business you get recommended depends on which AI you ask.

Verification Rate

What percentage of recommended businesses can be verified as real, operating in the specified city, via Google Places? This measures whether the AI’s recommendation is a real business you could actually hire.

Hallucination Rate

What percentage of recommended businesses cannot be found on Google Places at all? These are businesses the AI may have fabricated — names that don’t correspond to any real business listing.

Factual Claim Volume

When asked to describe a specific business, how many concrete factual claims does each AI platform make? We extract and categorize every claim — founding years, certifications, services, staff details — none sourced from verified operational data.
