LLM Friendly adds two capabilities to your WordPress site:
1) /llms.txt 
An LLM-friendly index of the website with main links and a list of latest items per post type. You can exclude individual entries from the feed via Settings → LLM Friendly → llms.txt → “Excluded items”.
2) Markdown exports 
For selected post types, the plugin exposes .md endpoints under: 
{base}/{post_type}/{path}.md 
Entries can override their Markdown body via the “Markdown override” sidebar panel (or Classic Editor metabox) and can also be excluded from export through the same settings page.
This is useful for LLMs, indexing bots, and users who prefer plain text. 
You can opt in to excerpts in llms.txt via <code>llms_show_excerpt</code>, and you can send <code>X-Robots-Tag: noindex, nofollow</code> for Markdown exports via <code>md_send_noindex</code> if you want Markdown-only consumers without search engine indexing. 
If the automatic Markdown conversion does not fit a post, use the “Markdown override” sidebar panel (Gutenberg) or the Classic Editor metabox to provide a custom Markdown or block-based replacement.
<h4>Key features</h4>
<ul>
<li>llms.txt endpoint with cached generation, optional excerpts, a configurable custom Markdown block, and a per-post exclusion list.</li>
<li>Markdown exports for selected post types with Gutenberg-to-Markdown conversion, per-post Markdown overrides (sidebar panel/metabox), and a per-post exclusion list shared with llms.txt.</li>
<li>Configurable base path for exports (e.g. “llm”) and per-post-type enable/disable toggles; changing the base path requires flushing rewrites.</li>
<li>Manual or automatic regeneration of the cached llms.txt with ETag/Last-Modified headers.</li>
<li>Optional X-Robots-Tag: noindex, nofollow for both /llms.txt and Markdown exports; the Markdown header is controlled by <code>md_send_noindex</code>.</li>
<li>Toggle excerpts in llms.txt via <code>llms_show_excerpt</code> to add one-line summaries under each item.</li>
<li>Optional site title/description overrides plus a sitemap URL field for the generated llms.txt.</li>
</ul>
<h4>Requirements</h4>
<ul>
<li>WordPress 6.0+</li>
<li>PHP 7.4+</li>
</ul>
If requirements are not met, the plugin displays an admin notice and does not run.

The md4AI plugin provides a powerful, multi-layered approach to Generative Engine Optimization (GEO).
<h3>1. Automatic AI Bot Detection (Zero-Config)</h3>
md4AI automatically detects requests from a comprehensive list of known AI agents (like GPTBot, ClaudeBot, Google-Extended, etc.) and serves them a lightweight, on-the-fly Markdown version of your content instead of the standard HTML theme. This ensures a clean, parsable data feed for LLMs right out of the box.
<h3>2. Per-Post Custom Markdown (Metabox)</h3>
The plugin adds a new metabox to your post and page editor, giving you full control over the AI-optimized version of your content. 
Serving an md version of the website is particular useful if your website has editors like Elementor / Beaver Builder / Divi Builder / other div bloated editors because bots usually skips complex and too much nested content.
<ul>
<li>Generate Custom Markdown: Convert your post’s content into Markdown with one click.</li>
<li>Manually Edit: Modify and enhance the Markdown to be exactly as you want AIs to see it.</li>
<li>(Optional) Enhance with AI: If you also use the <a href="https://wordpress.org/plugins/ai-services/" rel="ugc">AI Services</a> plugin, you can use the “Generate with AI” button to automatically add FAQs, discussion questions, or key takeaways extracted from your post.</li>
<li>Serve Enhanced Content: When an AI bot visits this specific post, it will be served your new, custom-tailored Markdown version, giving it far richer data.</li>
<li>Automatic Fallback: If you don’t create a custom version, the plugin falls back to the automatic on-the-fly conversion.</li>
</ul>
<h3>3. Site-Wide AI Instructions (llms.txt)</h3>
The plugin adds a new main page under ‘Utilities’ with dedicated tabs for configuration and insights. From here, you can create and manage a <code>llms.txt</code> file for your entire site.
<ul>
<li>What is <code>llms.txt</code>? This is a file, similar to <code>robots.txt</code>, that provides general instructions, context, and useful links to AI crawlers. It’s a new standard to help guide LLMs in understanding your site’s content and purpose.</li>
<li>Manage Content: Use the settings page to write your <code>llms.txt</code> content, which will then be served automatically to bots that look for it.</li>
<li>Learn More: You can find more details on this new standard at <a href="https://llmstxt.org/" rel="nofollow ugc">https://llmstxt.org/</a>.</li>
</ul>
This combination gives you full control, from automatic optimization to granular, AI-enhanced, per-post content and site-wide AI directives.
<h3>4. GEO/AIO Insights & Validation</h3>
The dedicated GEO/AIO Insights tab provides a unique validation mechanism for your site’s AI presence, offering measurable scores (0-100) on how well your brand is understood by Generative Engines.
<ul>
<li>The Validation Process: We ask a Large Language Model (LLM) to complete a “knowledge card” about your site (e.g., brand name, main topics, product categories).</li>
<li>Ground Truth Check: The AI response is immediately compared with real data extracted from your WordPress database (e.g., site title, author names, WooCommerce categories)</li>
<li>Final Score: Based on this cross-check, the insight provides a score for brand identity and technical relevance, highlighting exactly where the AI provided incorrect or insufficient data (hallucinations or missing data).</li>
</ul>
