Free AI Visibility Checker (2026)

Enter your website URL to see whether 14 major AI crawlers — GPTBot, ClaudeBot, PerplexityBot, Google-Extended, Applebot-Extended, and more — are allowed to access your content via robots.txt.

Live fetch as bot (curl-style)

Sends a real HTTP request to your URL using the selected AI crawler's user-agent — just like curl -A "GPTBot" https://your-site.com. Shows the exact response the bot would see.

Enter a URL above first.

Why AI visibility matters in 2026

  • ChatGPT Search, Perplexity, and Google AI Overviews now cite websites directly in answers.
  • If GPTBot, OAI-SearchBot, or PerplexityBot is blocked, you cannot be cited.
  • Blocking Google-Extended removes you from Gemini training but does not affect classic Google Search.

What to do next

  1. Unblock any AI crawler you want to be cited by in your robots.txt.
  2. Use the robots.txt generator to build a clean file.
  3. Publish AI-citable content (lists, comparisons, hard numbers, decision guides).
  4. Monitor referral traffic from chat.openai.com, perplexity.ai, and claude.ai in GA4.

Which AI bots should I allow?

  • Always allow: Googlebot, Bingbot — required for search + AI Overviews / Copilot.
  • Allow for AI citations: GPTBot, OAI-SearchBot, ChatGPT-User, ClaudeBot, PerplexityBot, Applebot-Extended.
  • Optional: Google-Extended, meta-externalagent, CCBot — allow if you want your content in LLM training data.
