llms.txt generator + validator · free
Generate your llms.txt, free
An llms.txt is a plain-text file that tells AI models what your site is and which pages matter, and this tool builds one from your own metadata and sitemap in a single pass.
What llms.txt is for
Think of llms.txt as a robots.txt for meaning rather than access. It lives at your root, names your site, summarizes what you do in a line, and links the pages you most want models to read. It is an emerging convention, and adoption is early, but it is cheap to ship and it cannot hurt.
This tool does not use an AI to write it. It pulls your title, description, OpenGraph tags, and sitemap, then slots them into a clean, spec-shaped template you can edit and publish.
Generate and validate
- ✓Generate: paste a URL and get a structured llms.txt built from your site name, summary, and key pages.
- ✓Validate: if you already have one, the tool checks it for the title, summary, sections, and links the spec expects.
- ✓Copy or save the result, refine the summary in your own words, and drop it at /llms.txt.

A real llms.txt is usually fix number two in a Ron report. The full audit finds the other four to eight, and tells you what ChatGPT, Claude, and Gemini actually say about you today. $39, once.
Questions
Do AI engines actually read llms.txt?
Support is uneven and early. Some tools use it, some ignore it, and the standard is still settling. It is low-effort to ship and gives you a clean, model-friendly summary of your site, so the downside is small.
How is this different from other generators?
Most do the same metadata-to-template work under the hood. This one ships an AEO-shaped template, validates an existing file against the spec, and is honest that it's templating your metadata, not inventing content.
Where does the content come from?
Your homepage title, meta description, OpenGraph tags, and headings, plus the URLs in your sitemap.xml. Nothing is fabricated. You then edit it to taste.
Where do I put the file?
At the root of your domain, served as plain text at /llms.txt, the same place your robots.txt lives.
