llms.txt checker

What this checks

llms.txt is a proposed convention for pointing AI agents at a plain-text summary of a site, instead of leaving them to scrape the rendered page. This tool fetches /llms.txt at the domain root and confirms it's real markdown — a Heading 1 as the first line, not a catch-all page that happens to answer 200 for any path.

What to look for

Not having one is normal; it's a new, optional convention, and most sites don't publish it yet. If you do publish one, the title shown here is that first heading — it's what an agent reading the file sees as the page's subject.
