How the index is built, what it measures, and what it means for your brand.
How does Slate decide which products rank?
Every category owns a versioned prompt pack and an approved product roster. Each week we put real buyer questions to ChatGPT, Perplexity, Gemini, and Claude, then attribute which products were recommended and which sources were cited. Those mentions become a visibility score — no pay-to-play, no self-reported data.
Which AI assistants does the index track?
ChatGPT, Perplexity, Gemini, and Claude — the four assistants B2B buyers actually use to shortlist software. Every score is an average of what these models recommend across a category's prompt pack.
How often are the rankings refreshed?
Weekly. Each published refresh gives buyers and brands a consistent point in time for comparing AI visibility and tracking how category positions change.
Is my brand's profile free?
Yes. Your public profile in the index is always free and always will be. Slate for Brands adds weekly tracking, movement alerts, and citation-gap analysis on top of the free, public record.
Something looks off — can I get it corrected?
Yes. Request a correction if anything looks off and it's reviewed against the same source-backed pipeline that powers the index. To track and improve your AI visibility over time, sign up to Slate.
