AI Visibility Ranking

Brands across every question in this category, ordered by GenRank score.

#BrandScore

The GenRank score sums each brand’s question-level visibility inside this category. Higher means AI names the brand more often and earlier. It is not bounded, so compare brands within one category, not across categories. Methodology

The questions behind this index

10

Each question with its top three brands by GenRank score and how many brands its answers named.

Rank trend

Rank trends are drawn once two weekly editions under the same methodology exist. Only the first edition is in so far.

Named by surface

Each cell: of the surface's 10 answers, how many named the brand. Darker means named more often.
