LLM Friendly is a WordPress plugin that exposes:

• /llms.txt — an LLM-friendly index of your site
• Markdown exports for selected post types under /{base}/{post_type}/{path}.md

Current version: 0.4.1

The goal is to make your site easier to navigate and consume for LLMs, indexing bots, and power users who prefer plain text.

• Generates an llms.txt index with links to your latest content, optional excerpts, and an optional custom Markdown block.
• Exposes .md endpoints for selected post types (posts, pages, custom post types) with Gutenberg-to-Markdown conversion and per-post Markdown overrides (Gutenberg sidebar panel or Classic Editor metabox); individual entries can override the Markdown body.
• Configurable base path for Markdown exports (e.g. llm) and per-post-type enable/disable toggles; changing the base path requires updating rewrite rules.
• Manual or automatic regeneration of the cached llms.txt, complete with ETag/Last-Modified headers.
• Optional X-Robots-Tag: noindex, nofollow header for both llms.txt and Markdown exports (md_send_noindex).
• Toggle excerpts in llms.txt via llms_show_excerpt to add one-line summaries under each item.
• Exclude specific items from both llms.txt and Markdown exports through the per-post-type exclusion picker in Settings → LLM Friendly.
• Outputs <link rel="alternate" type="text/markdown"> tags on singular views for supported post types.
• Optional site title/description overrides and sitemap URL for the generated llms.txt.

• WordPress 6.0+
• PHP 7.4+

If requirements are not met, the plugin shows an admin warning and does not run.

1. Upload the plugin folder to wp-content/plugins/llm-friendly/
2. Activate “LLM Friendly” in WordPress Admin → Plugins
3. Open Settings → LLM Friendly and configure:
   • Enable llms.txt
   • Enable Markdown exports
   • Select post types
   • Set base path (optional)
4. Save changes

• Open https://example.com/llms.txt
• Open a Markdown export, for example:
  • https://example.com/llm/post/hello-world.md
  • https://example.com/llm/page/about.md
• Enable llms_show_excerpt to include short descriptions in llms.txt:
  • Settings → LLM Friendly → llms.txt → “Show excerpts in llms.txt”
• Enable md_send_noindex to keep Markdown exports out of search indices:
  • Settings → LLM Friendly → Markdown → “Send X-Robots-Tag: noindex, nofollow for Markdown”
• Use the “Markdown override” sidebar panel (Gutenberg) or metabox (Classic Editor) to replace the generated Markdown with your own content or block markup; the override is applied per entry.
• Use “Excluded items” in Settings → LLM Friendly → llms.txt to search by title and exclude specific entries from both llms.txt and Markdown exports.
• To change the base path for exports (default llm), update “Base path” and re-save Permalinks if your server uses custom rewrites.

Note: if you are running Nginx in front of Apache (or have aggressive static rules), make sure .md and /llms.txt requests are routed to WordPress (not treated as static files).

If Markdown endpoints return 404 after changing the base path, flush permalinks and confirm that your web server does not short-circuit .md requests. On Nginx, ensure the PHP location block handles .md and /llms.txt before static file rules.

• Do not enable post types that should not be publicly accessible.
• Password-protected content should not be exported.
