llms.txt Checker
An llms.txt hands AI crawlers a clean map of your best content. Check whether yours exists — and whether it’s actually doing its job.
What it checks
Enter your domain and the tool fetches your /llms.txt, then scores it against best practice: does it exist, does it have a clear title and summary, is it organized into sections, and does it link to your key pages? It also checks for an llms-full.txt. You get a score and the specific things to fix.
Don’t have one yet? Build it in seconds with the llms.txt Generator, then make sure the bots can reach it with the AI Crawler Access Checker.

Do I need an llms.txt?
It’s not required, but it’s a fast, high-signal win — it helps AI crawlers find and correctly parse your best content instead of guessing, improving your odds of being cited.
