How is llms.txt different from robots.txt and sitemap.xml?

Robots.txt tells crawlers what they may access and sitemap.xml lists every URL for search engines. llms.txt is different: it is a short, human-curated markdown summary of your best content, written specifically to help AI models understand your site rather than to control crawling.

What is llms.txt

What is an llms.txt file and why it matters in 2026

An llms.txt generator creates a small markdown file that lives at the root of your site and gives AI models a curated overview of your most important pages. As more people search through AI assistants instead of traditional search, helping those models understand your site is becoming its own discipline — often called GEO or AEO.

Unlike a sitemap that lists every URL, llms.txt is a short, human-written highlight reel: your name, a one-line summary, and grouped links to your best content. It's designed to be read by large language models like ChatGPT, Claude and Perplexity. Pair it with schema markup and check your AI Overview readiness for a complete AI-SEO setup.

How to write a good llms.txt

How to create an llms.txt file that AI models actually use

A good llms.txt file is short and deliberate. Start with your site name as an H1, add a single blockquote summary that captures what you do, then group your best pages under clear section headings like Docs, Tools or Services. Each link gets a short description so the model knows what it points to.

Resist the urge to dump every page in — the whole point is curation. Link the pages you'd most want an AI to cite, keep descriptions factual, and update the file when your key content changes. Once it's live, make sure crawlers can reach it and that your important pages are discoverable via an XML sitemap.

Start with your name (H1) and a one-line summary (blockquote)
Group links under clear section headings
Add a short, factual description to each link
Curate ruthlessly — link only your best pages
Upload to your site root at /llms.txt
Update it whenever your key content changes
