llms.txt

A proposed convention for telling AI systems how to read your site. Emerging, not established.

What is llms.txt?

llms.txt is a proposed file, placed at the root of a domain, offering a structured guide to a site’s content for large language models, conceptually similar to robots.txt or a sitemap, but aimed at comprehension rather than crawling permission.

It is a convention that has been proposed and adopted by some publishers and platforms. It is not a standard that all major AI systems commit to honouring.

Does an llms.txt file get you cited?

Adoption and support are uneven and changing. Anyone telling you an llms.txt file will get you cited is overstating what is known.

It is cheap to implement and unlikely to hurt, which is a reasonable basis for doing it, and a poor basis for charging much for it.

What does Mindflow do about llms.txt?

We publish one, because it costs little and makes our own structure legible. We do not sell it as a lever, and we do not attribute visibility changes to it.

How do you check whether your site has an llms.txt file?

Check whether you have one at yourdomain.com/llms.txt. If you do, read it and confirm it still describes the site accurately.

Treat its absence as a low-priority gap rather than an emergency, whatever anyone selling implementation tells you.
