AI-powered LLMs.txt generation module for Magento 2 and Mage-OS stores. Automatically creates optimized llms.txt files using OpenAI to help AI systems understand your store content.

LLMs.txt is a proposed standard (similar to robots.txt) that helps AI systems like ChatGPT, Claude, and others better understand your website by providing a concise, structured summary of your most important content.
