Write an llms.txt file for your site
Tell AI assistants what your site is and which pages are worth reading. Fill in the form, copy the file, upload it to your root. Everything happens in this tab, and we never fetch your website.
- Runs in your browser
- Your site is never crawled or sent anywhere
- Follows the llms.txt specification
- Download a ready-to-upload file
1. Describe the site
The name is the only part llms.txt insists on. The summary is what an assistant reads before it decides whether to go further.
One sentence. What the site is, and who it is for.
Anything else worth knowing: what you sell, how the site is organised, what to ignore. Markdown is fine, but headings are not allowed here.
2. Add the pages worth reading
Group them the way you would explain your site to a new colleague. Order matters: what comes first gets read first.
Your llms.txt
Updates as you type. Nothing leaves your browser.
Your llms.txt will appear here as you fill the form in.To fix
Suggestions
Links: The file names your site but points nowhere. One link to your most useful page is a real improvement.
Save the file as llms.txt and upload it to the root of your site, so it answers at https://yourdomain.com/llms.txt.
What to do with the file
Generating it is the quick part. These three things are what make it useful.
- 1
Upload it to your root
Save it as llms.txt and put it at the root of your site, so it answers at yourdomain.com/llms.txt. That is the only place anything looks for it.
- 2
Keep it honest and short
Every link has to work and every description has to be true. A file that oversells the site is worse than no file, because it wastes the one chance you get to be summarised accurately.

Revisit it now and then
Update it when the site changes. It is a hand-written map, not a feed, so nothing updates it for you.
Common questions
- What is llms.txt?
- It is a plain text file at the root of your site that tells AI assistants what the site is and which pages matter. Think of it as a short reading list written for a machine, in Markdown, with one link per line.
- Does it actually do anything?
- It is a proposal published in September 2024, not a standard anyone is required to follow. Some AI tools read it, plenty do not yet, and no search engine has promised anything in return. It takes ten minutes and costs nothing, which is the honest case for adding one.
- Is this the same as robots.txt?
- No. robots.txt tells crawlers where they may go. llms.txt tells a reader what your site is about and where to start. They answer different questions and neither replaces the other.
- Do you crawl the URL I enter?
- No. The tool builds the file from what you type and nothing else. It never fetches your website, and the address you enter stays in your browser. Close the tab and it is gone.
- Which pages should I include?
- Start with the pages you would send a new customer to: what you do, your pricing, your most useful guide, how to get in touch. Ten good links beat a hundred. Anything you can live without goes under the Optional heading, which assistants are allowed to skip.
