About this tool
The AISearch Global llms.txt Checker looks for a plain-text llms.txt file
at your site's root — an emerging, community-proposed standard that gives AI systems a curated,
structured summary of your most important pages, similar in spirit to sitemap.xml but
written for language models. AISearch Global publishes its own at
aisearch.global/llms.txt.
Not yet as established as schema markup or robots.txt, but low-effort to add and a clear AEO signal.
Frequently asked questions
What is llms.txt?
llms.txt is an emerging, community-proposed standard — a plain-text file at a site's root that gives AI systems a structured, curated summary of a site's key pages and what each one covers, similar in spirit to sitemap.xml but written for language models rather than search-engine crawlers.
What does the llms.txt Checker report?
It checks whether llms.txt exists at your site's root, shows the first content line, and counts how many markdown-style links the file contains.
Do I need llms.txt if I already have good schema and robots.txt?
llms.txt is a newer, still-emerging signal — not yet as established as schema markup or robots.txt — but publishing one is low-effort and gives AI systems an explicit, curated map of your most important pages.
