Expose your WordPress site content through /llms.txt endpoints following the llmstxt.org specification. This makes your WordPress content easily accessible to Large Language Models (LLMs) in a structured, markdown format.

• llmstxt.org compliant: Implements the standard specification for LLM-readable content
• Multiple endpoints: /llms.txt (listing), /llms-full.txt (complete content), /llms-small.txt (excerpts), individual post endpoints
• XML sitemap integration: /llms-sitemap.xml with automatic SEO plugin integration (Yoast, RankMath, The SEO Framework, WordPress core)
• SEO integration: Respects noindex settings and adds X-Robots-Tag headers to prevent search engine indexing
• WooCommerce support: Product SKUs, prices, and metadata automatically included
• Hierarchical pages: Displays page hierarchy with proper indentation
• High performance: Built-in Laravel Cache integration with automatic invalidation
• WordPress shortcode processing: Converts shortcodes to readable content before markdown conversion
• Extensible: Developer hooks and filters for customization
• Configurable: Comprehensive configuration options for content filtering and formatting

Install via Composer:

composer require roots/acorn-llms-txt

Welcome to WordPress. This is your first post...

XML sitemap listing all llms.txt endpoints, automatically integrated with SEO plugins.

Access individual posts via /post-slug.txt (disabled by default for performance).

After publishing, edit config/llms-txt.php:

'post_types' => ['post', 'page'],

'content' => [
    'process_shortcodes' => true, // Process WordPress shortcodes
    'include_featured_image' => false,
    'include_author' => true,
    'include_date' => true,
    'include_taxonomies' => true,
    'excerpt_length' => 20,
    'date_format' => 'Y-m-d',
],

'limits' => [
    'max_posts' => 1000,
    'max_content_length' => 50000,
    'posts_per_section' => 50,
],

'exclude' => [
    'post_ids' => [123, 456], // Specific posts to exclude
    'password_protected' => true,
    'sticky_posts' => false,
],

'individual_posts' => [
    'enabled' => false, // Enable /post-slug.txt endpoints
    'post_types' => ['post', 'page'],
    'cache_ttl' => 3600,
],

'cache_ttl' => 3600, // 1 hour in seconds

'woocommerce' => [
    'enabled' => true, // Enable WooCommerce integration
    'include_price' => true, // Include product price
    'include_stock_status' => false, // Include stock status
    'include_product_type' => false, // Include product type
],

The package automatically respects SEO plugin settings and integrates with their sitemaps:

Content Filtering:

• Yoast SEO: Excludes posts/pages with noindex meta
• RankMath: Excludes posts/pages with noindex settings
• The SEO Framework: Excludes posts/pages marked as noindex

Sitemap Integration:

• Yoast SEO: Adds /llms-sitemap.xml to main sitemap index
• RankMath: Registers llms sitemap in sitemap array
• The SEO Framework: Creates custom sitemap endpoint
• WordPress Core: Integrates with wp_sitemaps system

Search Engine Protection:

• Adds X-Robots-Tag: noindex header to all llms.txt endpoints to prevent search engine indexing

Posts marked as noindex by SEO plugins will not appear in any llms.txt endpoints.

wp acorn llms-txt

wp acorn llms-txt clear-cache

Filter which post types are included:

add_filter('acorn/llms_txt/post_types', function ($postTypes) {
    return array_merge($postTypes, ['custom_post_type']);
});

Exclude specific posts:

add_filter('acorn/llms_txt/exclude_post', function ($exclude, $post) {
    return $post->post_title === 'Secret Post';
}, 10, 2);

Filter individual post data:

add_filter('acorn/llms_txt/post_data', function ($data, $post) {
    $data['custom_field'] = get_post_meta($post->ID, 'custom_field', true);
    return $data;
}, 10, 2);

Filter the complete posts collection:

add_filter('acorn/llms_txt/posts', function ($posts) {
    return $posts->sortBy('title');
});

Filter the entire document before output:

add_filter('acorn/llms_txt/document', function ($document) {
    // Modify the LlmsTxtDocument object
    return $document;
});

Filter final content before serving:

add_filter('acorn/llms_txt/content', function ($content) {
    return $content . "\n\n<!-- Generated at " . date('Y-m-d H:i:s') . " -->";
});

Filter XML sitemap before serving:

add_filter('acorn/llms_txt/sitemap', function ($sitemap) {
    // Modify the XML sitemap content
    return $sitemap;
});

Control sitemap integration:

add_filter('acorn/llms_txt/include_in_sitemaps', function ($include) {
    // Disable sitemap integration conditionally
    return false;
});

Add custom sections before default content:

add_action('acorn/llms_txt/before_sections', function ($document) {
    $section = (new \Roots\AcornLlmsTxt\Data\Section)
        ->name('Custom Section')
        ->addLink(
            (new \Roots\AcornLlmsTxt\Data\Link)
                ->title('Custom Link')
                ->url('https://example.com')
                ->details('Custom description')
        );

    $document->addSection($section);
});

Add custom sections after default content:

add_action('acorn/llms_txt/after_sections', function ($document) {
    // Add sections after default content
});

Add completely custom sections:

add_action('acorn/llms_txt/custom_sections', function ($document) {
    // Add your own sections
});

The package automatically invalidates cache when:

• Posts are created, updated, or deleted
• Post status changes
• Post metadata is updated

Manual cache clearing:

wp acorn llms-txt clear-cache

This package is optimized for performance with:

• Efficient caching: Laravel Cache integration reduces database queries
• Automatic cache invalidation: Updates cache only when content changes
• Memory optimization: Designed to handle large sites with thousands of posts
• Configurable limits: Control content length and post counts to manage resource usage

If content isn't updating, clear the cache:

wp acorn llms-txt clear-cache

Ensure Acorn routes are optimized:

wp acorn optimize

For sites with many posts, adjust limits in config/llms-txt.php:

'limits' => [
    'max_posts' => 500,
    'max_content_length' => 25000,
],
