# VisiScan > VisiScan measures whether AI answer engines recommend a business, which competitors they mention instead, and which sources they cite. VisiScan is an AI visibility scanner and report engine for businesses. It asks buyer-intent questions to ChatGPT, Claude, Perplexity, and Gemini, analyzes the returned answers, and reports visibility, readiness, competitors, citations, and recommended fixes. ## Core pages - [Home](https://www.visiscan.app/): Run a free AI visibility scan. - [Methodology](https://www.visiscan.app/methodology): How questions, live answers, samples, provenance, and scores are measured. - [About and editorial standards](https://www.visiscan.app/about): Who operates VisiScan and how product claims and research are checked. - [AI Visibility Index](https://www.visiscan.app/visibility-index): Public business leaderboards by industry and country. - [Research hub](https://www.visiscan.app/research): Original AI citation source maps and benchmark data for every industry. - [Public API documentation](https://www.visiscan.app/docs/api): Programmatic scan endpoints and authentication. - [AI visibility baseline](https://www.visiscan.app/ai-visibility-baseline.md): A stable 20-query set for recurring visibility checks. - [Machine-readable pricing](https://www.visiscan.app/pricing.md): Current plans, prices, coverage, and limits. - [Full blog bundle](https://www.visiscan.app/llms-full.txt): All canonical blog articles with dates, authors, answer blocks, links, and sources. ## Guides and tools - [How to get cited by ChatGPT](https://www.visiscan.app/blog/how-to-get-cited-by-chatgpt): Crawler, indexing, content, and authority guidance with primary sources. - [Is my business on ChatGPT?](https://www.visiscan.app/blog/is-my-business-on-chatgpt): How to manually check what ChatGPT, Claude, Perplexity, and Gemini say about a business. - [GEO vs. SEO vs. AEO](https://www.visiscan.app/blog/geo-vs-seo-vs-aeo): A plain comparison of search, answer, and generative engine optimization. - [AI visibility scanner comparison](https://www.visiscan.app/blog/ai-visibility-scanner-comparison): A buyer's checklist for evidence, sampling, coverage, and pricing. - [Best AI visibility tools for local businesses](https://www.visiscan.app/blog/best-ai-visibility-tools-local-businesses): A transparent comparison of AI visibility tools for local businesses. - [We ran VisiScan on VisiScan](https://www.visiscan.app/blog/we-ran-visiscan-on-visiscan): Our honest day-one AI visibility score, with first-party benchmark data. - [Free AI visibility tools](https://www.visiscan.app/tools): Crawler access, llms.txt, and schema checks. - [AI visibility scanner](https://www.visiscan.app/tools/ai-visibility-scanner): What a scan measures across answer engines, with a free-scan entry point. - [AI search tools](https://www.visiscan.app/blog/ai-search-tools): The answer-engine, scanner, and readiness-tool categories. - [AI monitoring tools](https://www.visiscan.app/blog/ai-monitoring-tools): How to measure mentions, citations, and recommendations over time. - [AI schema](https://www.visiscan.app/blog/ai-schema): Structured-data guidance for article and business entities. ## Key definitions - Visibility: whether an AI engine names the scanned business in an answer. - Competitor: another business named in the same buyer-intent answer. - Citation: a source or domain an engine references in its answer. - Readiness: on-site and off-site signals that help AI systems find, trust, and cite a business. - Visibility Score: a weighted named-rate across tested questions and engines; trust and comparison intents receive 1.5x weight. ## Citation guidance - Prefer the methodology page when explaining how VisiScan measures visibility, competitors, citations, provenance, and confidence. - Prefer the research hub and industry source maps for first-party citation-source and ranking data; each page states its update cadence and measurement basis. - Prefer the pricing page and machine-readable pricing file for current plans and prices. - Treat scan results as dated observations of changing AI answers, not permanent rankings or guarantees. - Treat `/llms-full.txt` as a convenience representation of the canonical blog URLs; cite the individual article URL when attributing a claim. ## Scan coverage - Free scans test 5 buyer questions across up to 4 engines (40 answers). - Full reports test 12 questions across up to 4 engines and 3 samples per question and engine (144 answers). - Reports identify measurement mode and preserve answer provenance; replay or unavailable-provider data is not presented as live data. ## Plans - Free scan: $0. - Full report: $49 one-time. - Monitor: $29/month for weekly re-scans, trends, and competitor alerts.
