What is llms.txt?
llms.txt is a proposed standard that gives large language models a curated, human-readable overview of your website. It lives at the root of your domain — similar to robots.txt — and uses clean Markdown to describe your products, documentation, and key pages.
Why AI systems need it
AI crawlers and assistants often struggle to prioritize what matters on large sites. An llms.txt file surfaces the most important URLs with short, factual summaries so models can cite and recommend your content more accurately.
How it differs from robots.txt
robots.txt tells crawlers where they may go. llms.txt tells AI systems what those pages mean. They complement each other; one does not replace the other.
How it differs from sitemap.xml
A sitemap lists URLs for discovery. llms.txt organizes the most valuable pages into readable sections with context — products, docs, blog posts, and more.
Benefits for your site
- Clearer AI understanding of your product
- Better chance of accurate citations
- Reduced hallucinations about your offerings
- A lightweight file that is easy to maintain
