The AI Visibility Index
See which companies AI names when buyers compare a category.
AI Search decisions need a repeatable baseline. The AI Visibility Index measures which companies appear in completed answers to category buyer questions across ChatGPT, Perplexity, Claude and Gemini. Because answers vary, we publish a 95% range and the observed check count, never a single-shot verdict.
AI visibility is the share of repeated category buyer-question checks where an assistant names a company. Every company is scored against the same answers. Measured, never modeled.
