ADG Markdown for AI Crawlers

When a known AI crawler (GPTBot, ClaudeBot, PerplexityBot, Google-Extended, and others) requests one of your posts or pages, this plugin returns clean Markdown of the main content on the same URL instead of the full theme HTML — no header, footer, sidebar or scripts. Regular visitors keep seeing your normal site.

It also generates a virtual llms.txt and llms-full.txt — a sitemap-style index of your content for AI tools — served at /llms.txt and /llms-full.txt without creating any physical files.

What it does

• Detects AI crawlers by User-Agent (the list is editable in the settings).
• Serves clean Markdown on the same URL with Content-Type: text/markdown, Vary: User-Agent and X-Robots-Tag: noindex.
• Works with any public post type — including WooCommerce products — plus a Markdown index for category, tag and custom-taxonomy archives.
• Configurable YAML front matter (title, url, date, author, tags, canonical) with per-field toggles.
• Include your own custom fields / ACF values in the front matter.
• Adds machine-readable Schema.org JSON-LD (title, dates, author, cover image, publisher).
• Generates virtual /llms.txt and /llms-full.txt.
• Caches the converted Markdown in post meta for fast responses; the cache is cleared automatically when a post is edited.
• Plays nice with page caches: sets DONOTCACHEPAGE (WP Rocket, W3 Total Cache, WP Super Cache, LiteSpeed) so bots are never served a stale HTML cache.
• Exclude content with a per-post “Hide from AI bots” checkbox or by category/tag slug.
• “View Markdown” link in the editor and post list — preview exactly what crawlers receive.

Privacy and external services

This plugin does not connect to any external service, send any data off your site, or load any remote scripts. All processing happens on your own server.

Good to know

• No .htaccess edits and no Composer — a built-in, zero-dependency HTML→Markdown converter is included.
• Does not interfere with SEO plugins, caches, or WooCommerce shop/cart/checkout pages.
• Private, password-protected and unpublished content is never served to bots — access rights are not bypassed.

Pro version

A Pro version is available with bot IP verification (anti-spoofing), bot-visit analytics with CSV export, a one-click self-test, and priority support. See the plugin’s settings page for details. The free version is fully functional on its own and is not time-limited.
