What is llms.txt?
llms.txt is a small text file that lives on a website. It works like a short map of the site. It lists the most important pages, with one short note for each page.
The file uses a simple format called markdown. People can read it. AI tools can read it too, very fast. The idea is simple: if an AI tool wants to learn about your site, this file gives it the key facts in one place.
The file always sits at the same address: yoursite.com/llms.txt. It is a bit like robots.txt, but robots.txt tells search bots what they may or may not visit. llms.txt does the opposite — it points to the pages you want AI tools to know about.
How to create an llms.txt file (3 steps)
- Fill in the form above. Write your site name, your web address, and one line about your site. Then add your best pages, grouped in sections.
- Copy or download the file. Use the Copy button, or download the file and keep the name
llms.txt. Do not change the name. - Upload it to your site. Put the file in the root folder of your website, so it opens at
yoursite.com/llms.txt. Then test it with the validator on this page.
Where to put the file
The file must go in the top folder of your website — the same place as your home page and your robots.txt file. The full address should look like this: https://www.yoursite.com/llms.txt
If the file sits inside a sub-folder, AI tools will not find it. After you upload it, type the address in your browser. If you can see the text of the file, the upload worked.
On WordPress, some SEO plugins can make this file for you. On other systems, you upload it by hand, the same way you upload any other file to your site.
Does llms.txt really work?
Here is the honest answer: the proof is weak.
Google's own guide for AI features says that Google Search does not use llms.txt. So this file will not change how Google sees your site.
A study by Ahrefs looked at 137,210 domains. It found that 97% of valid llms.txt files got zero requests from AI tools in May 2026. In plain words: almost no AI tool came to read those files.
Some AI tools may still read the file, and new tools may start. The file also costs almost nothing — it takes about 2 minutes to make with the generator above.
So treat llms.txt as a cheap experiment, not a promise. Do it once, then spend your real time on the thing that does work: clear, helpful pages on your site.
