PHOENIX

PressGEO today published The PressGEO AI Visibility Index — Q4 2026, a quarterly measurement of which brands AI engines recommend across 17 product categories.

The Index is built from 368,553 answers recorded over 90 days from ChatGPT, Claude, Copilot, Gemini, Perplexity. ## Key findings - Across 368,553 AI answers in 17 categories, engines named a tracked brand 36.8% of the time. - Copilot names brands most often (40.1%); ChatGPT least (31.6%). - The most dominant brand in any category is FreshBooks, named in 100% of Accounting answers. - Engines disagree most about Expense Management (disagreement score 41/100). - The biggest challenger gain: Fathom in Analytics, up 37.5 points to 62.1%. ## Methodology Every tracked brand in each category is asked that category's buyer questions on the same schedule across ChatGPT, Claude, Copilot, Gemini, Perplexity. An answer counts as a citation when the engine names the brand in response to a question that did not name it first. Rates are raw answers over the trailing 90 days; brands with fewer than 20 answers are excluded. Share change compares the most recent 45 days with the 45 before. Engine disagreement is the average spread of per-engine citation rates for each category's top five brands, scaled 0–100. PressGEO is measured by the same rules as every other brand. The full Index, per-category rankings and the downloadable dataset (CC-BY-4.0) are available at https://pressgeo.com/ai-visibility-index/2026-q4.
