llms.txt Generator
Give AI models and agents a clean, structured summary of your site — the emerging llms.txt standard. Enter your URL and we auto-crawl your homepage and sitemap on seosorted's servers to draft it for you (sign in free), or build it manually in your browser in seconds.
After generating, switch to "Build manually" — the fields are pre-filled with the generated result so you can tweak it by hand.
Enter your website URL and we'll crawl your homepage and sitemap to draft your llms.txt — or switch to the manual builder and fill it in yourself.
What llms.txt actually is
llms.txt is a simple, markdown-formatted file that gives AI models and AI agents a fast, structured overview of a website — what it does, and links to its most important pages — without needing to crawl and parse the entire site's HTML to figure that out. It lives at the root of a domain, the same place as robots.txt, and it's meant to be read directly by language models rather than rendered by a browser.
It isn't a codified standard the way the Robots Exclusion Protocol is, but it's a fast-growing convention among developers building AI agents and tools, and it costs almost nothing to add.
How llms.txt differs from robots.txt and sitemap.xml
The three files answer different questions. robots.txt tells crawlers what they're allowed to access. sitemap.xml is an exhaustive, machine-oriented list of every indexable URL for search engines. llms.txt is a curated, human-and-model-readable summary — not exhaustive, just the handful of pages and sections that actually matter, described in plain language a model can use immediately.
How to use the generated file
- Save the output as a file named exactly
llms.txt. - Upload it to the root of your domain, so it's reachable at
yourdomain.com/llms.txt. - Keep the linked pages list short and genuinely important — a cluttered llms.txt defeats the purpose of a concise summary.
- Update it whenever your site's core structure or most important pages change.
Frequently asked questions
What is llms.txt?
llms.txt is a proposed standard, similar in spirit to robots.txt or a sitemap, that gives AI models and agents a concise, markdown-formatted overview of a website: what it is, and links to its most important pages, in a format that's easy for a language model to parse quickly.
Is llms.txt an official web standard?
Not officially, in the way robots.txt is codified by the Robots Exclusion Protocol. It's an emerging convention proposed by developers working with AI agents, and adoption is growing but not yet universal. It's low-cost to add, so many sites are adopting it early.
Where do I put my llms.txt file?
At the root of your domain, the same place as robots.txt — for example, https://example.com/llms.txt. It should be a plain text file served with a text/plain or text/markdown content type.
Does llms.txt replace robots.txt or sitemap.xml?
No, it's complementary. robots.txt controls crawler access permissions, sitemap.xml lists every URL for search engine indexing, and llms.txt gives AI models a curated, human-readable summary of what your site is and which pages matter most.
