llms-full.txt
llms-full.txt is a file some websites publish with the full text of their key pages in one Markdown file, for AI tools to read at once.
llms-full.txt is a plain text file, usually at yourbrand.com/llms-full.txt, that holds the full text of a site's most useful pages in one go, written in Markdown. It's the companion to llms.txt, which only lists those pages with a short note on each.
The idea is that an AI tool can read one file and have everything, instead of fetching page after page.
How it differs from llms.txt
llms.txt is a short guide: what the site is, and links to the pages worth reading. llms-full.txt puts the content of those pages in the file itself. One is a table of contents, the other is the whole book.
The llms.txt proposal at llmstxt.org describes the short file. The full version is a habit that grew up around it, mostly on documentation sites. Mintlify, for example, creates both files for the docs it hosts.
Who reads it
So far it's mostly coding assistants and agents that look things up in product documentation. A developer can point their assistant at one file and it has the whole manual.
There's little sign the main AI search platforms use it when deciding what to say about brands. Google says its Search doesn't rely on special AI text files in its guide to optimizing for AI search.
Should you publish one?
If you sell software and have documentation, it's cheap and useful for developers. For most other brands, there are better places to spend the time, like making sure bots can read your pages at all.
For example, a coffee shop's site with a menu and an about page gains little from one. A coffee machine maker with 200 pages of manuals might find support questions get better answers when customers' assistants can read them in one file.

Our docs publish one, at /docs/llms-full.txt, with every docs page in full. Whether AI bots can read your own pages at all is what the Audit and Pages tabs in Website check. See Website and AI traffic.
