What is llms.txt?
llms.txt is a plain-text file at the root of a website — /llms.txt — that tells AI systems what the site is and lists its most useful pages in a short, structured form.
It does not grant access to anything; it is a map. An assistant that reads it can find the right page quickly and skip navigation, cookie banners and layout.
This directory checks every listed site for an llms.txt and records whether it answered, and when.
