Common questions
- What is llms.txt?
- llms.txt is a proposed convention: a markdown file at your site root that tells an AI assistant what your site is and which pages matter. It plays a similar role to robots.txt, but where robots.txt says what a crawler may fetch, llms.txt says what is worth reading.
- Where does the llms.txt file go?
- At the root of your domain, served as plain text or markdown: https://yourcompany.com/llms.txt. Some sites also publish llms-full.txt containing the full text of their key pages.
- Do ChatGPT, Claude or Perplexity actually read llms.txt?
- There is no public commitment from any major engine to read it, and no independent evidence that publishing one changes how often you are cited. It is a proposal that some sites have adopted early. The honest case for it is that it costs one file, not that it is known to work.
- How is llms.txt different from robots.txt or a sitemap?
- robots.txt grants or denies access, and a sitemap is an exhaustive machine-readable list of every URL. llms.txt is neither: it is a short, curated, human-written summary of what your site is and which handful of pages an assistant should read first.
- Does this tool publish the file for me?
- No. It reads your sitemap and drafts the file for you to copy. You edit the summary line and publish it yourself, because the one line that matters most is the one describing what you do, and that is not something to generate.
Do this first
An llms.txt is no use if the crawlers cannot fetch your site in the first place. Check that before you spend time on this one.
