AI Crawler Access Checker
Find out if ChatGPT, Perplexity, Claude, and Gemini can crawl your website. Enter any domain to instantly analyze your robots.txt for AI search engine access.
Why AI Crawler Access Matters
Invisible to AI = Lost Traffic
40% of searches now include AI-generated answers. If your robots.txt blocks AI crawlers, ChatGPT, Perplexity, and Gemini can't cite your content — even if you rank #1 on Google.
Different Bots, Different Rules
Each AI engine uses its own crawler. GPTBot serves ChatGPT, PerplexityBot serves Perplexity, ClaudeBot serves Claude. You need to allow each one individually for full AI visibility.
Easy Fix, Big Impact
Updating your robots.txt takes 5 minutes. Use our free generator to create the perfect configuration, then run this checker to verify.
Frequently Asked Questions
How does the AI Crawler Checker work?
The tool fetches your website's robots.txt file and analyzes the rules for each known AI crawler user-agent. It checks whether each AI bot is explicitly allowed, blocked, or has no specific rule (defaults to the general User-agent: * rule).
What AI crawlers does this tool check?
We check for GPTBot, ChatGPT-User, OAI-SearchBot (OpenAI/ChatGPT), ClaudeBot (Anthropic/Claude), PerplexityBot (Perplexity), Google-Extended (Google/Gemini), Applebot-Extended (Apple Intelligence), Meta-ExternalAgent, cohere-ai, Bytespider (ByteDance), and CCBot (Common Crawl).
What does it mean if an AI crawler is blocked?
If an AI crawler is blocked in your robots.txt, that AI search engine cannot index your content. This means your website won't appear in AI-generated answers from that platform. For example, blocking GPTBot means ChatGPT won't cite your site.
Is this tool really free?
Yes, the AI Crawler Checker is completely free with no signup required. For a more comprehensive analysis of all 11 GEO signals, you can run a full GEO scan on our homepage.
