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.
