Sign up for free →What is llms.txt?
llms.txt is a Markdown file at the root of your website, at yourdomain.com/llms.txt, proposed at llmstxt.org. It gives AI models a short map of your site: your site name, a one-line summary, and your most important pages grouped into sections, each with a short description. This generator builds that file from your own sitemap and page titles, so every link is a real page on your site.
How it works
- Enter your website. We read your robots.txt to find your sitemap, or try the usual sitemap addresses. With no sitemap, we use the links on your homepage.
- We choose the pages. Up to 100, spread across your sections so a large blog does not crowd out your services or docs. Login, cart, account, tag, search and pagination pages are skipped, as are pages in other languages.
- We read each page. Its title and meta description. Pages that do not load, are marked noindex, or point to a different canonical URL are left out.
- You review and download. The draft opens in an editor with a format check. If you already have an llms.txt, you see how it compares. We also show the AI crawler rules in your robots.txt.

Tips for a useful llms.txt
- Write meta descriptions. They become the descriptions in your file. A page without one is listed with its title only.
- Keep it short. List the pages that explain what you do: services, products, pricing, key guides. Move legal pages under Optional.
- Regenerate after big changes. New services, a new section or a renamed product are good moments to create the file again.
Frequently Asked Questions
llms.txt is a proposed standard (llmstxt.org) for a Markdown file at the root of a website, at yourdomain.com/llms.txt. It gives large language models a short, curated map of the site: the site name as a heading, a one-line summary, and sections of links to the pages that matter most, each with a short description. It is a guide to your content, not a set of access rules.
You enter your website address. We read your robots.txt to find your sitemap (or try the usual sitemap locations), follow sitemap index files, and collect the pages on your site. If there is no sitemap, we use the links on your homepage. We then choose up to 100 pages spread across your site sections, read each page’s title and meta description, drop pages marked noindex or pointing to a different canonical URL, and write the file. You can edit it before you copy or download it.
No. llms.txt does not block or allow any crawler. Access is controlled by robots.txt and by your server or CDN. The tool also shows what your robots.txt allows crawlers such as GPTBot, ClaudeBot and PerplexityBot to do. To change that, edit your robots.txt.
From your own pages. We use each page’s meta description, or its Open Graph description, or the first full paragraph on the page if neither exists. We never write descriptions for you, so a page without any of these is listed without one. Add a meta description to that page, or type one into the draft before you download it.
We read your current file, check its format, and show which pages from the new draft it does not list and which of its links are no longer in your sitemap. Your file is not changed.
The file lists at most 100 pages so it stays short enough to be useful. We skip login, cart, checkout, account, admin, search, tag and pagination pages, pages in other languages than your homepage, pages that did not load, pages marked noindex, and pages whose canonical URL points somewhere else. You can add any page by hand in the editor.
Download the file and upload it to the root of your website, so it opens at yourdomain.com/llms.txt. On a static site or a framework such as Next.js or Astro, put it in the public folder and deploy. On WordPress, upload it to the site root with your host’s file manager or FTP. Then open the address in your browser to check it shows plain text.
llms.txt is a proposal, not an adopted web standard, and search engines and AI assistants do not publicly confirm whether they read it. Treat it as a low-cost way to describe your site clearly, not as a ranking or citation guarantee.
No. We fetch your robots.txt, sitemap and pages when you click Generate, send the titles and descriptions back to your browser, and keep nothing. The file is built in your browser.
Yes. There is no sign-up. To keep it fair for everyone, each visitor can run a limited number of generations in a short period.
llms.txt is a short index of links. llms-full.txt is a companion idea where the full text of the important pages is included in one file. This tool writes llms.txt only.
