Can AI actually read your site?

ChatGPT, Claude, Perplexity and Gemini each send their own crawler. If your robots.txt blocks them, you will not be quoted in AI answers no matter how good your content is. This checks all 14 of them in a couple of seconds. Free, no signup.

Why this matters now

AI Overviews reach around two billion people a month. When someone asks ChatGPT or Perplexity for a recommendation, only a handful of sites get named. You cannot be one of them if the crawler that feeds the answer was turned away at the door.

Blocking is often accidental. A security plugin, a CDN bot rule, or a copied robots.txt from a template will quietly exclude GPTBot and Google-Extended without anyone deciding to.
