Free llms.txt Generator
Enter your site URL and get a ready-to-publish llms.txt: the Markdown index that tells ChatGPT, Claude, and Perplexity what your site is and which pages matter. Built from your real sitemap, not guesses.
How it works
From a URL to a file you can publish in the next five minutes.
Enter your site URL
The generator reads your robots.txt and sitemap to find the pages you actually publish.
Get a grouped index
Your pages, sorted into sections with a title and a one-line note each, plus a summary of what the site is.
Publish it at the root
Copy or download the file and serve it at /llms.txt, the path answer engines look for.
Publishing the file only helps if the crawlers can reach it. Check with the AI crawler checker, then see whether your pages are still current with the content freshness checker.
Frequently asked questions
What is llms.txt?
A Markdown file at the root of your site that tells AI answer engines what the site is and which pages matter. It is to language models roughly what robots.txt is to crawlers and sitemap.xml is to search engines: a short, readable index rather than a full page dump.
Is the llms.txt generator free?
Yes. You can generate up to 10 files a day with no account, and up to 30 a day when you sign in with Google. No credit card required.
Where do I put the llms.txt file?
At the root of your domain, so it resolves at yoursite.com/llms.txt. On most hosts that means dropping it in the public or static directory. On WordPress, upload it to the site root rather than the theme folder.
Does llms.txt actually do anything yet?
Adoption is early and no engine guarantees it reads the file. It costs one file to publish, it is trivially removable, and it gives you a single place to state what your site is in your own words. That is a reasonable bet at this price.
Where do the page descriptions come from?
From the URLs found in your sitemap. The generator never invents a page: every link in the output was in your sitemap, and any link the model produces that was not crawled is discarded before you see the file. Read the notes before publishing, since they are inferred from URL structure rather than page content.
What if my site has no sitemap?
The generator needs one, either declared in robots.txt or published at /sitemap.xml. If neither exists, publish a sitemap first; it matters more than llms.txt does, because ordinary search crawlers depend on it.
Does SiteSeed do this automatically?
Yes. Every site SiteSeed hosts ships llms.txt, rendered sources on each article, and instant IndexNow submission, and all of it stays current as new articles publish.
