This plugin makes your WordPress posts accessible to AI agents, LLMs, and other automated systems by providing a clean, structured Markdown version of the content. It’s designed to work out of the box with zero configuration.
Features: 
* Append <code>.md</code> to any single post URL to get the Markdown version (e.g., <code>/my-post.md</code>). 
* Responds with Markdown for requests with an <code>Accept: text/markdown</code> header. 
* Adds a <code><link rel="alternate"></code> tag to your posts for automatic discovery by crawlers. 
* Includes post metadata (title, author, date, tags, categories) as YAML front matter.

Lunatec Article to Markdown

Exposes a clean Markdown version of WordPress posts for AI agents, LLMs, and crawlers.

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>
