# llms.txt

**Definition:** llms.txt is a proposed convention for a Markdown file at the root of a website (/llms.txt) that gives large language models a curated, plain-text overview of the site: a title, a short summary, and sections of links to the most important pages with one-line descriptions. A companion file, llms-full.txt, contains the full text of those pages in one document.

The format is deliberately simple so that a model can read it without a parser: an H1 with the site name, a blockquote with a summary, optional free-text paragraphs, and H2 sections containing Markdown link lists of the form `- [Title](url): description`. An `## Optional` section marks links that can be skipped when context is limited.

This site publishes both [/llms.txt](/llms.txt) and [/llms-full.txt](/llms-full.txt), generated from the CMS on every content change.

## Frequently asked questions

### Who proposed llms.txt?

Jeremy Howard of Answer.AI published the proposal at llmstxt.org in September 2024. It is a community convention, not a web standard, and no major AI provider has publicly committed to reading it.

### Is llms.txt the same as robots.txt?

No. robots.txt tells crawlers what they may fetch; llms.txt tells a model what your site contains and where the best pages are. They are complementary.
