🐛 Report bug • Request feature ✨

📦 Installation

npm install vitepress-plugin-llms --save-dev

🛠️ Usage

Add the Vite plugin to your VitePress configuration (.vitepress/config.ts):

import { defineConfig } from 'vitepress'
import llmstxt from 'vitepress-plugin-llms'

export default defineConfig({
  vite: {
    plugins: [llmstxt()]
  }
})

Now, thanks to this plugin, the LLM version of the website documentation is automatically generated

[!NOTE]
For repositories with documentation in other languages: Please do not use this plugin, only English documentation is enough for LLMs.

[!TIP] You can add 📋 Copy as Markdown and 📥 Download as Markdown buttons for each page so that visitors can copy the page in Markdown format with just one click!

First, register a global component with buttons in docs/.vitepress/theme/index.ts:

import DefaultTheme from 'vitepress/theme'
import type { Theme } from 'vitepress'
import CopyOrDownloadAsMarkdownButtons from 'vitepress-plugin-llms/vitepress-components/CopyOrDownloadAsMarkdownButtons.vue'

export default {
  extends: DefaultTheme,
  enhanceApp({ app }) {
    app.component('CopyOrDownloadAsMarkdownButtons', CopyOrDownloadAsMarkdownButtons)
  }
} satisfies Theme

And tell VitePress to use an additional Markdown plugin that will insert them:

import { defineConfig } from 'vitepress'
import { copyOrDownloadAsMarkdownButtons } from 'vitepress-plugin-llms'

export default defineConfig({
  // ...
  markdown: {
    config(md) {
      md.use(copyOrDownloadAsMarkdownButtons)
    }
  }
})

✅ Good practices

1. Use `description` in the pages frontmatter

Typically, the list of pages in llms.txt is generated like this:

- [Tailwind v4](/docs/tailwind-v4.md)

As you can see, it's not very clear what's on this page and what it's for

But you can insert description in frontmatter in the docs/tailwind-v4.md file:

---
description: How to use shadcn-vue with Tailwind v4.
---

...

And the link in the generated llms.txt will display the page description:

- [Tailwind v4](/docs/tailwind-v4.md): How to use shadcn-vue with Tailwind v4.

Plugin Settings

See src/types.d.ts or

Example Configuration

Here is an example of how to configure the plugin with custom settings:

import { defineConfig } from 'vitepress'
import llmstxt from 'vitepress-plugin-llms'

export default defineConfig({
  vite: {
    plugins: [
      llmstxt({
        generateLLMsFullTxt: false,
        ignoreFiles: ['sponsors/*'],
        customLLMsTxtTemplate: `# {title}\n\n{foo}`,
        title: 'Awesome tool',
        customTemplateVariables: {
          foo: 'bar'
        },
        experimental: {
          depth: 2 // Generate llms.txt and llms-full.txt in root and first-level subdirectories
        }
      })
    ]
  }
})

This configuration does the following:

generateLLMsFullTxt: false: Disables the generation of the llms-full.txt file.
ignoreFiles: ['sponsors/*']: Ignores all files in the sponsors directory.
customLLMsTxtTemplate: Uses a custom template for the llms.txt file.
title: Sets a custom header in llms.txt, for your custom variables use customTemplateVariables.
customTemplateVariables: Sets custom variables for the template, replaces {foo} with bar.
experimental: { depth: 2 }: Generates both llms.txt and llms-full.txt files in the root directory and all first-level subdirectories, with each directory containing only files from that specific directory and its subdirectories.

Embedding content specifically for LLMs with `<llm-only>` tag

You can add a content that will be visible in files for LLMs, but invisible to humans, this can be useful for setting special instructions like "Refer to #basic-queries for demonstrations", "NEVER do ....", "ALWAYS use ... in case of ..." etc.

To do this, you need to wrap content with the <llm-only> tag:

<llm-only>

## Section for LLMs

This content appears only in the generated LLMs files without the `<llm-only>` tag
</llm-only>

Check out the Plugins API Guide for documentation about creating plugins.

<llm-only>Note for LLM...</llm-only>

Excluding content for LLMs with the `<llm-exclude>` tag

You can add a content that will be visible in files for humans, but invisible to LLMs, opposite of <llm-only>:

<llm-exclude>
## Section for humans

This content will not be in the generated files for LLMs
</llm-exclude>

Check out the Plugins API Guide for documentation about creating plugins.

<llm-exclude>Note only for humans</llm-exclude>

🚀 Why `vitepress-plugin-llms`?

LLMs (Large Language Models) are great at processing text, but traditional documentation formats can be too heavy and cluttered. vitepress-plugin-llms generates raw Markdown documentation that LLMs can efficiently process

The file structure in .vitepress/dist folder will be as follows:

📂 .vitepress/dist
├── ...
├── llms-full.txt            // A file where all the website documentation is compiled into one file
├── llms.txt                 // The main file for LLMs with all links to all sections of the documentation for LLMs
├── markdown-examples.html   // A human-friendly version of `markdown-examples` section in HTML format
└── markdown-examples.md     // A LLM-friendly version of `markdown-examples` section in Markdown format
