llms.txt Generator

Generate your llms.txt from your real website

The llms.txt file introduces your site to large language models: who you are, what you do, which pages matter. This tool writes it from your site real data, never from a generic template.

What llms.txt really is

It is a plain text file, placed at the site root like robots.txt, written in Markdown. It gives language models a short reliable summary of your activity plus a list of your important pages. Where robots.txt says what a bot may read, llms.txt says what it should understand.

Let us be precise about its status: Google has publicly stated it does not use the file, and adoption remains a minority. It is not a magic bullet. It stays worth doing for three reasons: publishing costs nothing, several tools and agents do read it, and the writing exercise forces you to state clearly what you do, which then benefits every page you own.

How to publish it

Frequently asked questions

Does llms.txt replace robots.txt?
No, they are complementary and independent. robots.txt controls access, llms.txt provides context. Publish both.
How long should it be?
Concise: one to five thousand characters is enough. Ten well-chosen pages beat two hundred raw URLs.
Do AIs really read it?
Some do, some do not. Server logs show several bots fetching HTML without ever requesting llms.txt. Publish it because it costs nothing, not because an effect is guaranteed.
Do I need an account?
No, the tool is free and requires no signup.
