About isvisible.ai
isvisible.ai checks a website's accessibility to AI platforms. The tool checks robots.txt and llms.txt, evaluates access rules for 13 AI crawlers including GPTBot, ClaudeBot, and Perplexity, and generates an instant 0–100 score plus a proxy-by-proxy access map to help you understand which AI platforms can access website content. The page says you can enter a URL directly to get a full report without an account or credit card; it also provides a public API, with the request format published at isvisible.ai/llms.txt.
