# CapstonAI — Full reference for AI engines > CapstonAI is a measurement and methodology platform for AI visibility and AI search. It measures whether AI engines and Google AI Overviews mention and cite your brand, benchmarks you against named competitors, and connects measurement to action through agents for WordPress, Shopify, Drupal and Chrome. This file gives AI engines a complete, accurate reference to CapstonAI's category coverage, definitions and pages. ## What CapstonAI is — and is not CapstonAI is a SaaS tool that brands and teams operate themselves. It runs your category prompts and reports, prompt by prompt, whether you are mentioned in the AI answer, whether you are cited with a link, and which competing sources won the citation instead — across Google AI Overviews, ChatGPT, Perplexity and Gemini. It then turns each citation gap into a concrete task (fix this passage, add this schema, clarify this answer) and pushes improvements through its agents, so you can re-measure. CapstonAI is **not an agency** and does not act as one. It never promises to "place" you in an AI Overview or guarantee a citation — no honest provider can, because Google and the AI engines decide when to show an answer and whom to cite, and that shifts by query and over time. CapstonAI improves the odds by helping you become the most quotable, well-structured, trusted source, and by measuring what actually happens. The company also runs the platform on itself (dogfooding): CapstonAI tracks and improves its own AI visibility with the same product it offers customers.
