# Vercatus > Vercatus is a machine visibility intelligence platform. It measures a website's machine readership — how much of the site search engines and AI answer engines can reach, understand and cite — and turns the measurement into decisions the next measurement verifies. Vercatus analyses a site from a sitemap: it samples pages across every template and language, fetches each one as several machine identities (plain HTTP, a browser, a browser without JavaScript, Googlebot, and the major AI crawlers) and compares the responses; extracts entities, factual claims and answerable questions into a knowledge graph; simulates retrieval over the site's own content to find questions it cannot answer; and produces evidence-graded findings, each with a metric and a control cohort so the next run can verify it. Every run also produces a plain-language executive brief for non-technical readers. ## Pages - [Home](https://vercatus.com/): what the product does and a sample report. - [Product](https://vercatus.com/product/): how it works, what a report contains, the workspace, what is next. - [Pricing](https://vercatus.com/pricing/): plans, worked examples, and what the price includes. - [About](https://vercatus.com/about/): why Vercatus exists and how it works with the sites it analyses. - [Documentation](https://vercatus.com/docs/): concepts, guides, API and CLI reference, security, limits. - [Our crawler](https://vercatus.com/crawler/): user agent, signature verification, crawl rate, allow-listing and blocking. ## Vocabulary - Machine visibility intelligence platform: the product category. Vercatus is one. - Machine readership: the metric family — a site's reach (share of pages each machine identity can obtain), understanding (entities and evidenced claims a machine extracts) and citability (share of questions the site's own passages answer). Published per run so two runs, or two domains, compare directly. ## Facts - Pricing: Single site $1,000 per month (1,000 pages per run). Portfolio $2,500 per month with three sites included, then $450 per site to ten and $300 beyond (2,500 pages per run). Enterprise on request, ten sites included. - Plans are fixed monthly prices with fixed run allowances; there is no usage metering. - Findings cite hypotheses from a knowledge base of 137 graded entries, each with sources and a revalidation date. - Analysis runs only on domains the customer has verified they control. - Contact: hello@vercatus.com
