llms.txt & AI Crawler Policy Monitor

Paste any llms.txt or robots.txt URL and we diff the raw file on a schedule. When a site adds an llms.txt, opens up an AI crawler, or quietly blocks one, you get an alert with the exact lines that changed, so AI access policy becomes a tracked signal instead of an afternoon of opening browser tabs.

Frequently asked questions

Can it tell me when a site publishes an llms.txt for the first time?
Yes. Add the /llms.txt URL even while it returns a 404. We record that 404 as the baseline, and when the file starts returning real content we alert you with the full text. That first publication is usually the clearest sign a company has started investing in AI readability.
How do I avoid alerts for irrelevant robots.txt edits?
Add a keyword condition so an alert only fires when the diff contains an AI crawler user agent name. Most robots.txt changes are sitemap additions, crawl-delay tweaks, or campaign path exclusions, and filtering those out keeps a large industry panel quiet enough that your team still reads it.
How many sites should I monitor?
Start with your ten closest competitors, tracking both robots.txt and llms.txt for each, on daily checks. Crawler policy moves in months, not minutes, so daily is plenty for a panel. Reserve faster checks for your own site, where an accidental block costs you AI visibility while it stays live.
