llms.txt Output

Overview

Quarto can generate llms.txt format output for your website, making your content more accessible to large language models and AI-powered tools. When enabled, Quarto creates an llms.txt index file and .llms.md markdown files for each page.

Enabling `llms.txt`

To enable llms.txt output, add llms-txt: true to your website configuration:

_quarto.yml

website:
  title: "My Documentation"
  llms-txt: true

Generated Output

When you render your site, Quarto generates two types of files:

`llms.txt` Index

An llms.txt file is created at the root of your site. This index lists all pages with their titles, using your site’s title and description from the website configuration.

Markdown Files

For each HTML page, a corresponding .llms.md file is created alongside it (e.g., guide.html gets guide.llms.md). These contain clean markdown versions of your content.

Content Conversion

HTML content is converted to markdown using Pandoc. Navigation elements, sidebars, footers, and scripts are removed. Tables, code blocks, callouts, and images are converted to standard markdown formats. Internal links are automatically rewritten from .html to .llms.md extensions.

Draft Handling

Draft pages are automatically excluded from both .llms.md generation and the llms.txt index. The 404 page is also excluded from the index.

Build Behavior

On full builds, all .llms.md files and the llms.txt index are regenerated. On incremental builds, individual .llms.md files are updated but llms.txt is preserved, matching the behavior of sitemap generation.
