Free tools
One tool so far. It checks whether crawlers can read a public page. It does not ask an assistant anything, and it does not say whether ChatGPT or any other assistant recommends you.

AI crawler & raw-HTML checker
Paste one public URL. The checker fetches that page without running JavaScript, then reads robots.txt, llms.txt and sitemap.xml on the same host. You get the robots.txt rules for GPTBot, OAI-SearchBot, ChatGPT-User, ClaudeBot, PerplexityBot, Google-Extended, Applebot-Extended, CCBot, Bytespider and xAI/Grok, plus the visible word count, whether a price appears in the HTML, JSON-LD types, and whether llms.txt and a sitemap exist. Nothing is stored, and there is no account.
A separate, smaller look at assistant answers
The checker stops at crawler access and raw HTML. The free mini report is a different thing: the same software asks Perplexity 3 buyer questions and emails a short PDF showing whether you were mentioned, who was named instead, and which pages were cited. The homepage describes that mini report and the one-time PDF report.
