llms.txt checker: can AI bots read your site?

Enter your domain. We check whether you have an llms.txt and whether ChatGPT, Claude, Perplexity and Google may read your site according to your robots.txt.

We do not store your domain. We only read /llms.txt, /llms-full.txt and /robots.txt.

Explainer

What is llms.txt?

llms.txt is a 2024 proposal by Jeremy Howard (Answer.AI): a markdown text file at /llms.txt that briefly tells AI models what you do and points to your most important pages. It starts with a title, then a short summary, then sections with links. A second file, llms-full.txt, holds the full text.

It is not a standard. No major AI provider publicly confirms that it reads llms.txt, and Google compared it to the keywords meta tag. It takes little effort, but do not expect a breakthrough from it.

Your robots.txt weighs more. It says whether an AI bot may fetch your pages, and one wrong rule makes you invisible in AI answers. More on that in 8 GEO myths marketers still believe.

FAQ

Frequently asked questions about llms.txt

No. The file is optional and no major AI provider confirms that it reads it. It takes little effort, so it does no harm, but your robots.txt and the content of your pages weigh more.

llms.txt is a short index: a title, a summary and links to your key pages. llms-full.txt puts the full text of those pages in one file. Both are optional.
