This plugin replaces the Gutenberg block editor (or the classic TinyMCE) on the edit screen with <a href="https://github.com/Ionaru/easy-markdown-editor" rel="nofollow ugc">EasyMDE</a>, a markdown editor based on CodeMirror, fine-tuned to work smoothly with the WordPress admin panels.
The content is saved with the markdown syntax in the database and is rendered on the frontend thanks to the <a href="https://parsedown.org" rel="nofollow ugc">Parsedown</a> PHP library after being sanitized via WordPress native filters.
That’s pretty all you should know. It’s under active development, keep in touch and feel free <a href="https://wordpress.org/support/plugin/markup-markdown/" rel="ugc">to drop a line on the forum</a>, <a href="https://wordpress.org/support/plugin/markup-markdown/reviews/" rel="ugc">to let a rating</a> or even support me by buying a coffee !

Just a fact: all the main AI GPTs generate Markdown by default. If you can't beat 'em, join 'em! I LOVE this plugin, as I can now create AI style websites on the WordPress platform. If you notice: all the main commercial AI sites have a similar "A.I. Style". Which is - dark or light mode, a chat box, and the most important thing: Markdown. Anyway, I'm using this plugin. Great stuff!



My one nitpick - The plugin generates configuration files in wp-content. This is bad news and there is no reason for it. On many sites wp-content is publicly exposed to the internet. Anyway, this data should be move to site options in the database.


AI responds in Markdown

Disable Wordpress's native Gutenberg or TinyMCE editor in favor of a Markdown editor.

Markdown for AI Agents is a lightweight WordPress plugin that enables HTTP content negotiation for your site’s content. When a client (like an AI agent or a custom script) requests a page with the <code>Accept: text/markdown</code> header, the plugin intercepts the request and returns a clean, structured Markdown representation of the post or page content.
This is ideal for AI crawlers, RAG (Retrieval-Augmented Generation) systems, and non-browser clients that prefer machine-friendly text over complex HTML.
Important note: This plugin is primarily a developer/integration tool. Human visitors browsing your site will never see any difference — the Markdown output is only served when explicitly requested via the <code>Accept: text/markdown</code> HTTP header. Normal browser requests always receive the standard HTML page.
Key Features:
<ul>
<li>Automatically detects <code>Accept: text/markdown</code> headers.</li>
<li>Converts HTML content to clean Markdown using the League HTMLToMarkdown library.</li>
<li>Strips away theme layout, navigation, headers, footers, and sidebars — serving only the main content.</li>
<li>Adds useful HTTP response headers: <code>Content-Type: text/markdown</code>, <code>Vary: Accept</code>, and <code>X-Markdown-Word-Count</code>.</li>
<li>Respects WordPress visibility rules and filters.</li>
<li>No configuration required — works out of the box for posts, pages, and custom post types.</li>
</ul>
<h3>How It Works</h3>
This plugin uses a standard web technique called HTTP content negotiation. The same URL on your site can serve different representations of the same content depending on what the client asks for:
<ul>
<li>A regular browser sends <code>Accept: text/html</code> → receives your normal HTML page.</li>
<li>An AI agent sends <code>Accept: text/markdown</code> → receives a clean Markdown version of the same page.</li>
</ul>
No extra URLs, no duplicate content, no configuration needed. The plugin hooks into WordPress’s <code>template_redirect</code> action, detects the <code>Accept</code> header, captures the rendered HTML, converts it to Markdown, and returns it with appropriate headers.
<h3>Why Markdown for AI Agents?</h3>
When building RAG (Retrieval-Augmented Generation) applications or AI pipelines that ingest web content, HTML is extremely noisy. A typical WordPress page contains thousands of tokens worth of HTML tags, inline styles, navigation menus, scripts, and layout markup — none of which carries meaning for an AI model.
Serving clean Markdown instead can reduce token consumption by up to 60%, which means:
<ul>
<li>Lower API costs — fewer tokens ingested when loading pages into vector stores or LLM pipelines.</li>
<li>Faster processing — less text for the model to parse, filter, and discard.</li>
<li>Better retrieval accuracy — higher signal-to-noise ratio improves the quality of RAG results.</li>
<li>Simpler pipelines — no need for custom HTML stripping logic on the client side; the plugin handles it server-side.</li>
</ul>
Any AI agent, crawler, or ingestion script that sends <code>Accept: text/markdown</code> in its request header will automatically receive the clean Markdown version — no extra URLs, no separate endpoints, no changes to your content workflow.
