About llms.txt Generator

This llms.txt generator builds an llms.txt file, a plain Markdown summary at the root of your site, proposed at llmstxt.org, that points AI assistants and agents to the pages that matter, such as documentation, pricing, policies or product guides. Enter the site name and a one-line summary, add a few paragraphs of detail, then build sections of links, each with a title, URL and short note. Links that can be skipped when an assistant needs less context go into the Optional section.

The generator lays the file out the way the proposal describes, with the name as the main heading, the summary as a quote and each section as a list of links. Download it as llms.txt and upload it to your site root. Keep in mind that it's a proposal rather than a standard, AI services decide for themselves whether to read it, and it doesn't allow or block any crawler; robots.txt does that. See which AI crawlers your site lets in with the AI Crawler Checker. Everything runs in your browser.

FAQ

llms.txt Generator: questions and answers

What is an llms.txt file, and what is it for?
A Markdown file at /llms.txt, proposed at llmstxt.org, that gives AI assistants a short overview of your site and links to its most useful pages.
Do ChatGPT, Claude or Google read llms.txt?
Each AI service decides for itself, because llms.txt is a proposal rather than a standard. It only takes a few minutes to add, but don't expect it to change your traffic on its own.
Does llms.txt block AI crawlers?
No, it only describes your site. To allow or block crawlers such as GPTBot, use robots.txt, which the Robots.txt Generator can write for you.
What goes in the Optional section?
Pages that are useful but not essential, such as changelogs, background articles or older docs. The proposal lets tools skip this section when they need a shorter context.
Where do I put the llms.txt file?
In the root of your site, next to robots.txt, so it opens at https://example.com/llms.txt.
