# Project LLMs.txt > Project LLMs.txt is a WordPress plugin that publishes the structured Markdown > files ChatGPT, Claude, Perplexity, Gemini, and other AI assistants use to > understand a site. Install once, stay ready. The plugin generates /llms.txt (a structured index), /llms-full.txt (the same index with full page content inlined), and individual per-page Markdown files. Free version on WordPress.org; Pro adds auto-regeneration, custom templates, ACF and custom-field mapping, per-page overrides, and a post-editor AI Preview. Both files exist for this site: https://projectllmstxt.com/llms.txt is the index, and https://projectllmstxt.com/llms-full.txt is that index followed by the full Markdown content of every page, doc, and post listed below. ## Pages - [Home](https://projectllmstxt.com/): What the plugin does, how it works in three steps, feature highlights, pricing overview, and FAQ. - [Features](https://projectllmstxt.com/features): The full feature tour with screenshots - clean Markdown output, ACF field mapping, WooCommerce detail, WP-CLI, hooks, and what Pro adds. - [Pricing](https://projectllmstxt.com/pricing): Free forever, Pro $49/yr (1 site), Studio $99/yr (5 sites), Agency $199/yr (unlimited).
