The AI 100 is WhereDoIRank's name for the flagship cross-category board: the brands with the strongest overall AI visibility across every tracked category, ranked like an index of listed companies.
Category rankings answer "who wins CRM?"; The AI 100 answers "who wins AI recommendation overall?" — the brands that models name first, in the most categories, most consistently. Think of it as the market-cap leaderboard of AI visibility.
Like any index, membership is the story: entering The AI 100 means multiple models recommend you across multiple buying contexts, and falling out means the answers moved on.
