About AI Crawler Access Checker
AI Crawler Access Checker verifies if AI crawlers such as GPTBot, ClaudeBot, PerplexityBot, and other active AI crawlers can reach a given website. The tool reads only the public robots.txt file of the entered domain, which is the same file accessible to any browser or crawler. It compares the robots.txt rules against a list of ten currently active AI crawlers to determine which ones are blocked. This check helps ensure that website content can be cited in AI-generated answers from platforms like ChatGPT or Perplexity. The process requires no login and is completed instantly by entering a website URL. The tool is designed for website owners, content creators, and SEO professionals who want to confirm AI crawler accessibility. It highlights potential issues where default hosting templates or security plugins may inadvertently block AI crawlers.

Frequently asked questions about AI Crawler Access Checker
What does the AI Crawler Access Checker do?
The tool checks whether AI crawlers such as GPTBot, ClaudeBot, PerplexityBot, and other active AI crawlers can access a given website by reading only the public robots.txt file of the entered domain.
Who should use this tool?
Website owners, content creators, and SEO professionals who want to confirm AI crawler accessibility and ensure their content can be cited in AI-generated answers from platforms like ChatGPT or Perplexity.
Does this tool require a login or store any data?
No login is required, and the tool only reads the public robots.txt file—nothing about the site is stored.
Why would AI crawlers be blocked on my site?
Common reasons include default hosting or CMS robots.txt templates blocking all bots by name, or security plugins adding blanket AI-bot blocks without realizing it also affects crawlers that feed AI answer engines.
Does blocking these crawlers actually hurt me?
If you want your content cited in ChatGPT, Perplexity, or Google AI Overviews, a blocked crawler means it never reads your pages, so even high-quality content may not be cited.
Can I block some AI bots while allowing others?
Yes, a common setup is to block AI training crawlers like Google-Extended or Applebot-Extended while allowing answer-engine crawlers like GPTBot, ClaudeBot, or PerplexityBot to drive citations and traffic.
