An Ask AI box for Jekyll sites, and the llms.txt and llms-full.txt files it reads. Readers ask a question in their own words and get an answer written from your pages, with links to the pages it used.

This site runs it. Press Ask AI in the bottom right corner, or Ctrl+/, and try:

  • How do I add this to my Jekyll site?
  • Does it work on GitHub Pages without a plugin?
  • 可以改按钮的位置吗？

What it is

Four small files you copy into your site. It is not a gem and not a plugin, because GitHub Pages does not run custom plugins. Everything is plain Liquid, so it builds on stock GitHub Pages.

  • llms.txt: an index of your site in the llmstxt.org shape. Title, description, one link per page.
  • llms-full.txt: the text of every page in one file, each page under its own heading with a Source: link. AI tools can read your whole site from it.
  • The Ask AI box: one script tag, added by _includes/onetag.html. It reads llms-full.txt in the reader’s browser and answers from it.

The two llms files need no key and no account. They are useful on their own.

Add it to your site

  1. Copy _includes/onetag.html and _includes/onetag-pages.html into your _includes/ folder.
  2. Add {% include onetag.html %} right before </body> in your layout.
  3. Copy llms.txt and zz-llms-full.txt to the root of your site.

The full steps are on Install.

What you do not need

  • No plugin and no gem. It works on stock GitHub Pages, with “Deploy from a branch”.
  • No server and no crawler. The files are rebuilt with your site, so they are never out of date.
  • No AI provider account. The key is a OneTag AI key, made to sit in a public page. Free: 1,000,000 tokens a month.
