Free AI crawler & TDM checker
Can AI companies train on your site?
EU copyright law lets AI companies mine your content unless you opt out in a machine-readable way, and the EU AI Act requires AI model makers to respect that opt-out. We read your robots.txt and TDM signals and show which AI training crawlers are allowed in.

Questions
Do I have to block AI crawlers?
No. This is your choice, not a legal duty. But if you don't opt out in a machine-readable way, EU law lets AI companies use your content for training.
How do I opt out of AI training?
Disallow AI training bots like GPTBot, ClaudeBot, CCBot and Google-Extended in robots.txt, and optionally publish a tdm-reservation signal.
Will blocking AI crawlers hurt my Google ranking?
No. Google-Extended only controls AI training use; normal Googlebot search indexing is separate.
Does this affect my Risk Score?
No. It's shown as advice only, because opting out is a choice rather than a legal requirement.
Is the checker free?
Yes. You can scan any website once a day for free with no sign-up.
