The AI Visibility Index is an independent project that measures whether AI assistants — ChatGPT, Perplexity, Gemini, Google AI Overviews and Claude — name a brand when buyers ask for the best option in its category. We publish the scores openly so businesses, journalists and researchers can see who AI recommends, and who it leaves out.
A growing share of buyers ask an AI assistant before they search Google. The AI names a short list of brands — and if you're not on it, you're invisible at the moment of decision, with no analytics to tell you. This index makes that invisible layer measurable and public.
For each brand we ask a current frontier AI model five real buyer questions for its category (e.g. "What are the best CRM software?") and count how often the brand is named. Score = mention rate, 0–100. 70+ = AI reliably names you; under 40 = largely invisible. Snapshot: June 2026, US market, 60 brands across 12 categories. Anyone can reproduce any score live with the free AI Visibility Checker, or pull the full machine-readable dataset at /index.json.

Journalists and analysts: the headline finding this edition is that 30% of 60 major brands tested are largely invisible in AI answers and 28% were never named once. Custom industry lists, quotes, or methodology details on request: rileycraig14@gmail.com.
