# RankPirate llms.txt Generator

> Free tool that crawls a website and builds an llms.txt file following the llmstxt.org v2 specification.

## What it does

Enter a URL. The generator fetches homepage HTML, extracts title/description/Open Graph metadata, discovers important internal pages, prefers markdown alternates when pages advertise `rel="alternate" type="text/markdown"`, and assembles a ready-to-publish `/llms.txt` file.

## Why it matters for AI rankings

AI agents and coding assistants increasingly start at `/llms.txt` to understand a site before crawling HTML. A clear index plus markdown page alternates reduces token waste and improves how models describe your brand.

## How to use the output

1. Host the file at `https://yourdomain.com/llms.txt`
2. Publish markdown versions of key pages (pricing, product, docs)
3. Advertise them with `Link: rel="alternate"; type="text/markdown"` and `rel="describedby"` pointing at `/llms.txt`
4. Optionally support `Accept: text/markdown` on the same canonical URLs

## Limits

- Free preview with no account; email unlocks the full file for copy/download
- Complements — does not replace — quality product content and schema on your site
- Google Search does not treat `llms.txt` as a special ranking factor; it is for AI/agent discovery
