AI Robots.txt Checker
Check if your website allows AI crawlers (GPTBot, ClaudeBot, PerplexityBot, Google-Extended) to access your content. Free, instant results.
Why AI Crawler Access Matters
AI search engines like ChatGPT, Perplexity, Claude, and Google Gemini use web crawlers to index content. If your robots.txt blocks these crawlers, your content won't appear in AI-generated answers — meaning you're invisible to a growing segment of search users.
Which AI Crawlers Should You Allow?
At minimum, allow GPTBot (OpenAI/ChatGPT), ClaudeBot (Anthropic), PerplexityBot, and Google-Extended (Gemini). Blocking these crawlers means your competitors get cited instead of you.
