Markdown for AI Agents vs SMTP2GO for WordPress –

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 Accept: text/markdown 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 Accept: text/markdown HTTP header. Normal browser requests always receive the standard HTML page. Key Features: Automatically detects Accept: text/markdown headers. Converts HTML content to clean Markdown using the League HTMLToMarkdown library. Strips away theme layout, navigation, headers, footers, and sidebars — serving only the main content. Adds useful HTTP response headers: Content-Type: text/markdown, Vary: Accept, and X-Markdown-Word-Count. Respects WordPress visibility rules and filters. No configuration required — works out of the box for posts, pages, and custom post types. How It Works 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: A regular browser sends Accept: text/html → receives your normal HTML page. An AI agent sends Accept: text/markdown → receives a clean Markdown version of the same page. No extra URLs, no duplicate content, no configuration needed. The plugin hooks into WordPress’s template_redirect action, detects the Accept header, captures the rendered HTML, converts it to Markdown, and returns it with appropriate headers. Why Markdown for AI Agents? 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: Lower API costs — fewer tokens ingested when loading pages into vector stores or LLM pipelines. Faster processing — less text for the model to parse, filter, and discard. Better retrieval accuracy — higher signal-to-noise ratio improves the quality of RAG results. Simpler pipelines — no need for custom HTML stripping logic on the client side; the plugin handles it server-side. Any AI agent, crawler, or ingestion script that sends Accept: text/markdown in its request header will automatically receive the clean Markdown version — no extra URLs, no separate endpoints, no changes to your content workflow.
