Question 1

What is llms.txt?

Accepted Answer

llms.txt is a plain-text file at the root of a website that tells AI assistants who you are, what you offer and which pages matter most. It is an emerging convention used by ChatGPT, Claude, Perplexity and other assistants when deciding what to quote.

Question 2

Where do I put the llms.txt file?

Accepted Answer

Save it as llms.txt in your site root so it loads at https://yourdomain.com/llms.txt. It must be served as plain text, not inside a subfolder.

Question 3

Is this llms.txt generator free?

Accepted Answer

Yes. Create a free account and you can generate one llms.txt file every month at no cost. Paid plans remove the limit.

Question 4

How is llms.txt different from robots.txt?

Accepted Answer

robots.txt controls which crawlers may access your pages. llms.txt describes what your site is about and points assistants to your most useful pages.

Question 5

How often should I update llms.txt?

Accepted Answer

Refresh it whenever your key pages, products or positioning change — roughly every few months for most sites.
