More and more people ask ChatGPT, Claude or Perplexity instead of Google. The free AI check shows in a few seconds whether these assistants can find, read and understand your website – and what you can improve.
Free, no sign-up. Up to 2 checks in 12 hours.
What is checked
- Reachability and HTTPS
- Access for AI crawlers (robots.txt)
- Structured data (Schema.org)
- Readable without JavaScript
- Sitemap
- llms.txt
- Title, description, language, contact details
- Load time and page size
- Bot protection that locks out AI crawlers
- AI door (MCP endpoint) – extra, no points
- From 80 points: test the AI door live · from 85: ask a real AI
To be honest: nobody can reliably check from the outside whether a website is “in ChatGPT”. The AI check shows whether your site meets the requirements for AI assistants to use it.
We store the checked address, the score and your IP address only in hashed form to prevent abuse. If you ask the real AI, only the domain is sent to Anthropic (Claude). More in the privacy policy.
