llms.txt generator and validator

Paste your site. The generator reads your homepage and sitemap and writes an llms.txt from your real pages. The validator fetches the llms.txt you already have and checks it line by line against the spec, including whether the links still work.

What llms.txt is, plainly

It is a plain text file at yoursite.com/llms.txt, written in Markdown, that tells AI tools which pages on your site matter and what each one is about. The idea comes from llmstxt.org. Think of it as a short, curated map, the opposite of a sitemap that lists everything.

What goes in it. One H1 line with the site name. A blockquote with one or two sentences on what the site is. Then H2 sections, each holding a list of links in the form - [Page name](https://url): what it covers. A section called Optional holds pages a tool can skip when it is short on room.

Does it get you cited today? Honestly, not yet on its own. As of now, none of the big answer engines have said they read it when deciding what to cite. What it does do is give any tool or agent that fetches your site a clean, correct summary instead of guessing from your nav. It costs ten minutes and it is where things are heading, so it is worth having, as long as it is accurate. A file full of dead links is worse than none.

The checks the validator runs. The file exists and is served as text. The first line is an H1. There is a blockquote summary. Sections are H2 only. Every list item is in the link form. Links are absolute. Most links have a description. A sample of the links actually respond. The file is not huge.
