Every week, the same frozen set of 4 question phrasings is sent to OpenAI, Anthropic, Google Gemini, and Perplexity — through each provider’s official API, with active web search, never through a consumer chat interface.
Same market, same questions, repeated on a fixed schedule — not a single sample. No AI model is paid or influenced; this page reports what each one already says.
Answer Share — the share of measured responses that name a given company. 55.6% means the company appeared in 55.6% of the responses collected for this market.
Market concentration — the share of responses naming at least one of the top 3 companies: how fragmented or concentrated the answers are for this market.
Citation Share — the share of citations linking directly to a company’s own website, among companies whose domain we’ve matched. Shown as n/d where we haven’t matched a domain, or 0% where the domain is known but never cited directly — AI models often cite a review aggregator instead of the company’s own site.
The date at the top of this page is when this market was last measured. Numbers refresh weekly.
