From each site's robots.txt rules for the homepage, read as the robots.txt standard (RFC 9309) says. robots.txt is a request, not a lock: this shows what sites ask, not what AI companies do. Sites whose robots.txt we could not read are left out. The list of sites was picked by Kavel and is not a sample of the web. Part of Kavel's AI crawler study, built with AI.
