# llms-full.txt

Category: [AI Search & GEO](https://seo-geo-glossary.com/en/glossary/category/ai-search-geo/) › [Controls & opt-out](https://seo-geo-glossary.com/en/glossary/category/ai-search-geo/controls-opt-out/)

**llms-full.txt** is a file that makes the complete text of a website or documentation available in one Markdown document. It complements llms.txt, which only lists pages with links. The name is a convention used by some providers and is not part of a standard.

## How do llms.txt and llms-full.txt differ?

The llms.txt proposal was published by Jeremy Howard on September 3, 2024. It describes `/llms.txt` as a Markdown file with an H1 title, a short summary in a blockquote and sections with lists of links. The name llms-full.txt does not appear in the specification, including version 2 from August 10, 2026. The spec proposes that pages offer a clean Markdown version at the same URL, with `.md` appended or replacing the file extension.

Documentation platform Mintlify generates both files. In its documentation, llms.txt is an index of pages with links and descriptions, and llms-full.txt combines the entire documentation into a single file as context. Its structure is not prescribed, so each provider decides how to order the pages and what to include.

## How widely is it used?

It is a community convention. Google's Search Central documentation says you do not need to create new machine-readable files or AI text files to appear in AI features such as AI Overviews. In the sources checked, major AI providers have not confirmed that they read llms-full.txt. Having the file therefore does not guarantee visibility in AI answers (assessment).

## Example

The Anthropic documentation publishes such a file at `platform.claude.com/docs/llms-full.txt`. When fetched on October 6, 2026, it was larger than 10 MiB, which is more than fits into the context window of many models.

A freely chosen structure could look like this:

```txt
# Example Inc.

## Page: Pricing
URL: https://example.com/pricing
(Markdown text of the page)

## Page: Contact
URL: https://example.com/contact
(Markdown text of the page)
```

|---|---|---|---|---|
| robots.txt | IETF standard: RFC 9309 (September 2022) | /robots.txt | tells crawlers which URLs they may fetch; per the RFC not a form of access authorization | Crawlers; Google's common crawlers always respect it for automatic crawls |
