Free AI visibility tools
Two questions decide whether an AI answer engine can recommend you: can it read your site, and does it already name you when a buyer asks. These four tools answer both. All of them are free, none of them ask you to sign up, and none of them store what you check.
ChatGPT Visibility Checker
Does the answer engine know I exist?
Ask a buying question the way your customers would and see whether an AI engine names your brand, cites your domain, or recommends someone else.
AI Readiness Checker
Can the engines read my site at all?
Eight deterministic checks on your site: crawler access, llms.txt, Organization and FAQ schema, canonical and meta tags, server-rendered copy, and whether an about and pricing page exist.
AI Crawler Access Checker
Am I blocking the crawlers by accident?
Reads your robots.txt and tells you whether GPTBot, ClaudeBot, PerplexityBot, or Google-Extended are blocked, including by a blanket rule you never wrote.
llms.txt Generator
What should my llms.txt say?
Build the markdown file assistants read to work out what you are and which of your pages answer what. Copy or download it, then drop it at the root of your domain.
What these tools do not tell you
A single check is a snapshot. AI answers move around week to week, they differ by engine, and they change depending on how the question is phrased. If Perplexity names you today it may not tomorrow, and one run cannot tell the difference between a real improvement and noise. Watching the same questions on a schedule across ChatGPT, Perplexity, Claude, and Gemini, and tracing which pages the answers are built from, is the paid CueScout product.
