Is your site blocking AI crawlers?
How it works
We fetch your robots.txt and parse it the way Google does: user-agent groups, Allow and Disallow with longest-match precedence, and the*and$wildcards. Each of the 12 AI user agents is tested against your homepage path, falling back to the wildcard group when it has no group of its own. "Partial" means the homepage is allowed but some paths are not. Nothing you enter is stored.
