First time? Start here
You do not need SEO knowledge or code. This tool creates a text file describing your website and useful pages.
- Enter your website name. This is the only field always required.
- Recommended: add one or two sentences explaining what your website does and who it helps.
- Add useful pages if you want. Each page you add needs both a page name and its complete web address. Ordinary website links are fine.
- Click Generate & validate, review the results, then download llms.txt. The file is not published until you upload it to your website.
Grey example text is a placeholder, not a completed field. Optional fields may be left empty. Never enter passwords, API keys or private links.
1. Generate a file
Already have a published llms.txt file? Check it here (optional)
2. Review your file and download
Your file appears here after generating. You can also paste an existing llms.txt file. If you edit this box, click Validate editor; clicking Generate again replaces these edits with the form above.
Text is displayed literally, not executed or rendered as HTML. Review before publishing. Download saves the current editor even if it has validation issues. Edits clear the previous report when the field loses focus.

What llms.txt can and cannot do
llms.txt is a community proposal. It is not a Google ranking requirement, does not guarantee AI citations and does not replace robots.txt, sitemaps or access controls. This is a lightweight format review, not a certification or a test of linked-page availability.
