Simple LLMS.txt Generator

A WordPress plugin that dynamically generates an llms.txt file for Large Language Models (LLMs) and automatically includes it in your XML sitemap. Designed specifically to work with WordPress VIP and other managed WordPress environments that restrict static file creation.

Frequently Asked Questions

Does this plugin write files to the server?

No. It generates the content dynamically per request, which is actually ideal for WordPress VIP environments. The platform's robust page caching ensures excellent performance without any static file management.

Can I customize the content that appears in llms.txt?

Yes! Use the admin settings page for basic customization, or use the llms_txt_content filter for advanced modifications.

Will this work with multisite?

Yes, the plugin works with WordPress multisite installations. Each site will have its own llms.txt file and settings.

How do I verify it's working?

1. Visit yoursite.com/llms.txt directly in your browser
2. Check your XML sitemap at yoursite.com/wp-sitemap.xml
3. Look for the llms.txt entry in the sitemap

What if I need to exclude certain pages or posts?

Currently, the plugin includes pages by menu order and posts by date. For more complex filtering, use the llms_txt_content filter to modify the output.
