AI Crawler Access Monitor
Watch a robots.txt or llms.txt file and catch the moment a site changes which AI crawlers it allows or blocks. AI flags new or removed rules for bots like GPTBot, ClaudeBot, and Google-Extended, and ignores harmless reordering and comment edits so you only see real policy shifts.

Frequently asked questions
How do I monitor a robots.txt or llms.txt file for crawler changes?
Paste the URL of the file, for example the site's robots.txt or llms.txt. We fetch it on a schedule and compare it to the last version. When an allow or block rule for an AI crawler is added or removed, you get an alert. It works on any publicly reachable file.
Which crawler changes will it actually flag?
AI focuses on rules that change access for AI bots, such as a new or removed Disallow for GPTBot, ClaudeBot, Google-Extended, or PerplexityBot. Reordered lines, whitespace, and comment tweaks that do not change behavior are ignored, so you only hear when a site genuinely opens up or locks down.
How quickly am I notified, and is there a cost?
You choose. Instant alerts catch a policy change within minutes, useful when tracking how a publisher treats AI crawlers, or a daily or weekly digest groups changes across many files into one summary. It is free to start, so you can begin watching a file right away.
