What is llms.txt and should my Magento store have it?

llms.txt is the robots.txt for AI engines, a structured page index at /llms.txt that tells ChatGPT, Claude, Perplexity, and Google AI Overviews which pages on your site are worth citing. It lists your CMS pages, top categories, blog posts, services, with one-line summaries.

Most Magento stores don’t even know llms.txt exists. Our open-source module auto-generates it on every cron, alongside robots.txt and sitemap.xml. Free win.
