How to reach it

Tool	What it says it does
`check_ai_citations`	Check whether ChatGPT, Perplexity and Gemini cite a domain when asked the given questions. Send 1 to 5 realistic buyer questions (each at least 5 characters). Returns, per AI, how many questions cited the domain. Each check calls paid AI APIs, so the limit is 5 checks per 30 minutes per IP.
`check_ai_crawler_readiness`	Check whether AI crawlers (GPTBot, ClaudeBot, PerplexityBot, Google-Extended, Bytespider, CCBot) can read a website, and whether it has llms.txt, schema markup and server-rendered content. Returns a 0-100 score and the failed checks.
`validate_llms_txt`	Validate an llms.txt file. Pass a website URL to fetch and check its /llms.txt (or /llms-full.txt), or pass the llms.txt text itself. Returns a 0-100 score, valid true/false, and each check. Use it to check a site or to review text drafted for the user. If both are given, the url is used.

Free, no signup: AI crawler check, llms.txt validator, ChatGPT/Perplexity/Gemini citation check.
