llms.txt is a proposed site-level text file that guides AI systems toward important URLs and context — useful as a hint layer, not a substitute for verification or accurate identity.
llms.txt is a community-proposed convention for a plain-text file at the root of a site (similar in spirit to robots.txt) that points AI systems toward preferred pages, summaries, and context. It is a hint and routing mechanism, not a cryptographic verification standard and not a guarantee that models will comply.
Sites are large. Themes are noisy. AI crawlers and tools benefit from an explicit map of which URLs represent the organisation, policies, product docs, or canonical about information. llms.txt aims to provide that map in a simple format.
Self-published guidance is necessary but incomplete. Selective third-party identity records add an external, fetchable snapshot of who the business is. Together: first-party routing (llms.txt, schema) + third-party selective documentation (passports). Deep dive: llms.txt and business verification.
AI Verified publishes an llms.txt that maps key surfaces (registry, methodology, wiki pillars). Business operators can similarly list their About page, passport URL, and policy pages. Site llms.txt · Gold distribution.
Is llms.txt required by law or by Google?
No. It is a voluntary convention. Implementation varies by tool.
Does publishing llms.txt verify my business?
No. It publishes guidance you control. Verification requires evidence and, for elevated tiers, domain attestation challenges.
Should my llms.txt link to my AI Verified passport?
If you have a published passport, yes — including it points tools at a stable identity URL.
