How this is measured
Famewise generates the category-level questions consumers ask AI assistants, then asks them to current OpenAI GPT, Anthropic Claude and Google Gemini models — each question with web search on and off. An extraction model records every brand named in every answer, the position of its first mention, and the sentiment toward it. Brands are ranked by visibility: the share of this category's answers that name them at least once. Share of mentions is a different cut of the same data — each brand's slice of every brand mention in the category. Every number reflects the latest scheduled run.
