What do AI enginesfind at your root?
Two files decide what an AI engine can do with your site: robots.txt says who may come in, llms.txt says what is worth reading. We check both, and split the 27 crawlers into the 16 that power answer engines (and can cite you) from the 11 that only collect training data.
Two requests: /robots.txt and /llms.txt. We do not store the domain, and nothing is written to your site.
This is one check out of 126
robots.txt is the doorway. It is not the room.
Letting a crawler in does not make the page worth quoting. ProvenVisible runs 126 deterministic checks across SEO, answer-engine readiness and generative citation: each with the evidence attached and a line describing how the finding could be proven wrong.
