AI crawler access control

Build a modern robots.txt policy for AI crawlers.

Decide which AI training bots, search bots, and user-triggered fetchers can access your public website. Generate copy-ready robots.txt rules, audit existing rules, and create an llms.txt summary without uploading private files.

Why this tool exists

      

        

          
AI crawlers split into roles

          
Training crawlers, AI search crawlers, and user-triggered fetchers are not the same. A good policy handles each role separately instead of blocking every bot with one broad rule.

        

        

          
Visibility has trade-offs

          
Blocking AI search crawlers may reduce how often your pages appear in AI-generated answers. Blocking training crawlers can still be a reasonable content protection choice.

        

        

          
Robots.txt is not security

          
Robots.txt communicates crawler preferences. Sensitive pages still need authentication, noindex rules, server access control, or WAF rules when real protection is required.

        

      

    


    

      

        This site provides technical templates, not legal advice. Always review generated rules against your content strategy, crawler logs, and hosting setup before publishing.
      

    


    

      
Publish a policy without losing useful search traffic

      
Start with one decision per crawler role. A publisher might permit ordinary search indexing of public articles, block a training crawler from a licensed archive, and allow a user-triggered fetcher to retrieve a page when a reader explicitly asks for it. These are separate choices. Do not use a single wildcard Disallow: / unless you intend to block every compliant crawler from the whole site.

      
    
        
  1. Write down the public paths, private paths, and any query-string routes that matter. A rule for /archive/ is not the same as a rule for the homepage.
    2. 
        
  2. Use the generator to create a draft and the analyzer to test a real URL for each selected user agent. Include a public article and a path you expect to block.
    3. 
        
  3. Compare the draft with your existing /robots.txt so it does not remove important search-engine rules or a sitemap declaration.
    4. 
        
  4. Publish to the root of the correct hostname, fetch the live file without logging in, then check server logs. A local preview cannot prove that a CDN or firewall will let the crawler through.
    5. 
      

      
The optional llms.txt generator creates a map of public resources, not an access policy. It cannot override robots rules, authentication, copyright, or a provider's own crawler behavior. For parsing details, use the Google robots.txt specification alongside each provider's crawler documentation.
