llms.txt Validator
Paste an llms.txt and find out whether a model could actually use it.
This checks the file, not the site. It never fetches, so it cannot tell you whether a listed URL returns 200 — only whether a model would have something it could resolve. And llms.txt itself is a community proposal, not an official requirement from Google or the major AI providers: a clean file is worth having if you want one, but nothing here is a ranking or citation input.
Paste an llms.txt on the left and the findings appear here.
