What is llms.txt and do I need one?
Quick answer: llms.txt is a plain-text file at your domain root that gives AI systems a curated, machine-readable map of your most important content and facts - like robots.txt, but for large language models. It helps AI answer engines find and correctly summarize your brand. Any site that wants to be understood by AI should have one.
AI systems have limited context and often mis-summarize sites built for humans. llms.txt lets you hand them a clean, prioritized index: who you are, what you offer, your key pages, and the facts you want quoted - in Markdown they can parse instantly.
A strong setup pairs llms.txt (the map) with llms-full.txt (the full text) and per-page Markdown mirrors, so an AI can retrieve your canonical content without wrestling with your theme, scripts, or navigation.
