Our index contains 97,843 listed websites with a valid llms.txt; 44,329 of those also publish an llms-full.txt. 35,213 listed files are classified as platform-generated. 3 listed sites are owner-verified.
These counts describe our index, not a census of the web. Daily additions show when we first recorded a valid file, not when the publisher first adopted llms.txt. Category counts overlap. Unlisted, invalid and blocked sites are excluded from listing breakdowns.
