llms.txt generator

llms.txt is a file at your domain root that tells AI crawlers (ChatGPT, Perplexity, Gemini, Claude) which pages you want read. Fill this in, get a copy-ready file. Free, no signup, nothing leaves your browser.

How it works: the spec wants an H1 title, an optional one-line summary in a blockquote, then sections of links (- [Name](url): description). Put the file at https://yoursite.com/llms.txt and reference it from robots.txt if you like. It complements - never replaces - sitemap.xml.

Site / project name

One-line summary (blockquote, optional)
