jekyll-llms

Jekyll plugin that produces LLM-friendly formats alongside a regular website.

Namely: llms.txt, Markdown sidecars, and HTML alternate links to sidecars.

Installation

Add to Gemfile and run bundle install

group :jekyll_plugins do
  gem "jekyll-llms"
end

Add to _config file:

plugins:
  - jekyll-llms

Output

• /llms.txt: Markdown index of included entries.
• *.md: source-body sidecars for included Markdown-source entries.
• HTML <link rel="alternate" type="text/markdown" href="..."> tags pointing to sidecars.

Sidecars are source bodies, not HTML-to-Markdown conversions. Front matter is removed. Liquid is rendered unless render_with_liquid: false is set. HTML-source entries stay linked by their original URLs.
