❓ What does this plugin do?
It optimizes your site for AI crawlers with LLM.txt & llm-full.txt
With one click, it generates two smart files in your root directory: 
• llm.txt: a customizable file you control with Markdown and shortcodes 
• llm-full.txt: a comprehensive, auto-generated map of your site’s most important content (excluding noindex posts)
Together, these files follow the emerging llmstxt.org standard—making your content easier for generative AI engines to discover, understand, and cite.
✨ Why Use This Plugin?
🧠 LLMs rely on high-quality content — But they need help finding and understanding it.
🚀 Boost your AI visibility — Ensure your best posts, pages, and taxonomies are crawled and understood by AI bots.
🛠️ Fully configurable — Choose which post types and taxonomies are included. Add custom Markdown descriptions.
🧾 SEO-safe — Automatically skips noindex content (Yoast, Rank Math, native WordPress).
🌍 Multilingual support — Works with WPML to group content by language.
🧩 Shortcode-powered — Use [llm type=”post” amount=”5″] to dynamically inject content into llm.txt.
🔒 No bloat, no tracking — Just clean code and output.
<h3>Features</h3>
✅ Generates llm.txt and llm-full.txt files in your site root 
✅ Uses Markdown formatting and shortcodes in llm.txt 
✅ Automatically updates files on content or taxonomy changes 
✅ Easy settings panel in WordPress admin 
✅ Supports WPML (optional) 
✅ Fully respects noindex meta data 
✅ Preview and regenerate files anytime 
✅ Uses SimpleMDE editor for rich Markdown editing
<h3>Troubleshooting</h3>
<h3>llm.txt or llm-full.txt return 404?</h3>
If you see a 404 error when visiting <code>/llm.txt</code> or <code>/llm-full.txt</code>, go to your WordPress admin, navigate to Settings > Permalinks, and simply click “Save Changes” to flush the permalink cache. Then try accessing the files again.
<h3>How to Use</h3>
<ol>
<li>Activate the plugin through the ‘Plugins’ menu in WordPress.</li>
<li>After activation, go to Admin > Settings > LLM.txt to configure the plugin settings.</li>
<li>Adjust your preferences and save changes.</li>

pixeline Generative Engine Optimization – LLM.txt

Boost AI visibility with LLM.txt & llm-full.txt—auto-generate smart, crawlable content files for ChatGPT, Claude, Gemini & more.

Umay Ajans

Modern AI agents (ChatGPT, Claude, Perplexity, Gemini, etc.) work much better with Markdown than HTML. Umay AI Markdown inspects the incoming <code>Accept</code> header and, only when <code>text/markdown</code> is requested, intercepts the response and serves a clean, agent-friendly Markdown representation of the page.
Browsers, search engines, and any client that does not explicitly ask for Markdown receive the unchanged HTML response. There is no settings page, no cron job, and no external service call.
Key features
<ul>
<li>Zero configuration — install, activate, done.</li>
<li>Only triggers when <code>Accept: text/markdown</code> is present. Regular visitors and search engines are never affected.</li>
<li>Hybrid content extraction: uses <code>the_content</code> for posts/pages, falls back to a DOM-based extractor for archives, taxonomies, and the homepage.</li>
<li>Powered by the industry-standard <a href="https://github.com/thephpleague/html-to-markdown" rel="nofollow ugc">league/html-to-markdown</a> library.</li>
<li>Transient-cached for 12 hours per URL (sha256-keyed). Auto-invalidated on <code>save_post</code>, term edits, theme switches, and menu updates.</li>
<li>Built-in IP rate limiter (30 requests / minute by default) to mitigate abuse.</li>
<li>Strict input sanitization, header injection protection, libxml entity hardening (XXE-safe), and full WordPress Coding Standards compliance.</li>
<li>PSR-4 autoloaded, namespaced OOP code. No globals.</li>
<li>Sends <code>Vary: Accept</code>, <code>X-Robots-Tag: noindex</code>, and <code>X-Content-Type-Options: nosniff</code> on every Markdown response.</li>
</ul>
What gets sent to AI agents
Each Markdown response includes a YAML front-matter block with the page title, site name, canonical URL, and ISO-8601 generation timestamp, followed by the page body converted to Markdown. Navigation, footer, sidebars, scripts, styles, comment forms, related posts, and other page chrome are stripped before conversion.
Filters
Two filters are available for advanced customization:
<ul>
<li><code>umay_mdn_bypass</code> — Return <code>true</code> to skip Markdown handling for the current request.</li>
<li><code>umay_mdn_cache_ttl</code> — Override the default 12-hour cache lifetime (in seconds, minimum 60).</li>
<li><code>umay_mdn_rate_limit</code> — Override the default 30-requests-per-minute rate limit.</li>
<li><code>umay_mdn_converter_options</code> — Modify the league/html-to-markdown converter options array.</li>
</ul>

Umay AI Markdown
