Generate an llms.txt for your site
Name the site, write one line about it, list the pages that matter. This produces a plain-text file to serve at /llms.txt so an assistant can describe you accurately.
After generating
Serve the file at /llms.txt on the exact host, then run the llms.txt check. It fetches the file from outside your network and reports whether it exists, whether it has real content, and how many pages it links to. Keep it honest: it describes pages that are already public and readable.
Questions
- What is llms.txt?
- A Markdown file at /llms.txt that names the site, gives a one-line summary, and links the pages that matter so AI tools can describe and cite it accurately. The format is described at llmstxt.org: an H1 title, an optional blockquote summary, then sections of links.
- Do assistants actually read it yet?
- Some do, not all, and it is not a ranking or indexing signal. It is a young convention: cheap to add, no downside, but do not expect it to fix content a crawler cannot otherwise read.
- Where do I put the file?
- At your site root, served over HTTPS at /llms.txt, the same place robots.txt lives. It is plain text and should be fetched without a login.
- How is this different from robots.txt?
- They do different jobs. robots.txt controls which paths a crawler may fetch. llms.txt describes what the site is and points at the pages worth reading. A site can allow every crawler and still have no llms.txt, or the reverse.
