Can ChatGPT, Claude, Gemini & Perplexity read your site?
Paste your URL. We check your robots.txt and tell you instantly whether the major AI crawlers are allowed. If you're blocking them by accident, AI engines can't cite you — even when you'd rank.
Why this matters
When someone asks ChatGPT, Claude, Gemini, or Perplexity a buyer-intent question — "best CRM for small business", "trusted UK eco-packaging supplier" — the AI answers using content it has either trained on or fetched in real-time. If your robots.txt blocks those crawlers, your brand isn't even in the pool of possible answers.
Most sites block AI crawlers by accident. The default robots.txt generated by older SEO plugins didn't know about GPTBot, ClaudeBot, PerplexityBot, or Google-Extended. A broad Disallow: / under User-Agent: * blocks them all unless overridden.
The fix is a 4-line edit. For each AI crawler you want to allow, add an explicit block in your robots.txt:
User-Agent: GPTBot Allow: / User-Agent: ClaudeBot Allow: / User-Agent: PerplexityBot Allow: / User-Agent: Google-Extended Allow: /
AI can access your site. But does it actually recommend you?
Crawler access is step 1. The bigger question is whether AI engines actually cite your brand when buyers ask. Run a free AI visibility audit and find out.
