AI Crawler Access Checker

Free tool · AI crawler access check

AI Crawler Access Checker

If AI crawlers cannot access your website, your content may not be available for AI-powered search and answer systems to discover and potentially cite. Enter your domain to check whether common AI crawlers are allowed or blocked by your site's robots.txt.

Check access for crawlers associated with ChatGPT, Claude, Perplexity, Google and other AI systems.

Reads your public robots.txt, nothing else. No login, nothing stored.

What Is an AI Crawler Access Checker?

An AI crawler access checker analyzes your website's robots.txt file to determine whether specific AI crawlers are allowed to access your site.

Your robots.txt file can contain rules that allow or block individual crawlers, groups of bots, or all crawlers through wildcard rules. This tool identifies those rules and shows the access status for each supported AI crawler.

What This AI Crawler Checker Checks

  • GPTBot: Checks if GPTBot is allowed or blocked.
  • ClaudeBot: Checks the access rules for ClaudeBot.
  • PerplexityBot: Checks if PerplexityBot can crawl your site.
  • Google-Extended: Checks rules for Google's AI crawler.
  • Other AI agents: Find relevant crawler rules in your robots.txt.

What This Tool Does Not Check

  • Does not check if an AI crawler is actually visiting your site, only if it is allowed
  • Does not verify crawler identity, only the robots.txt rules
  • Does not check JavaScript rendering, use the AI Visibility Check
  • Does not check content loaded after JavaScript execution
  • Does not check private or staging robots.txt files behind authentication

Why Check AI Crawler Access?

AI systems rely on crawlers to discover and retrieve information from websites. Your robots.txt file can control whether certain crawlers are permitted to access your site.

A single broad Disallow rule can unintentionally block multiple AI crawlers.

Checking your robots.txt helps you understand which AI crawlers are permitted to access your website and which ones are blocked.

How to Fix Blocked AI Crawlers

If an AI crawler is blocked, review your robots.txt rules.

  • Find the User-agent rule that applies to the crawler.
  • Check the Disallow directive blocking crawler access.
  • Look for broad wildcard rules like User-agent: *.
  • Remove or update any unintended blocking rules.
  • Add an Allow rule if access needs to be restored.
