WhoTrainedOnMe by WhoTrainedOnMe

Stop Training AI With Your Activity.

WhoTrainedOnMe alerts you when a site may be using your activity to train AI — and helps you opt out or protest. No tracking. Built for data transparency.

Websites are training AI on your data— without your consent.

✅ Get Notified
As you browse, WTOM alerts you when a site may be using your data to train AI models like ChatGPT, Claude, Gemini, and others.

✉️ Opt Out or Protest
Find opt-out forms, protest emails, and AI policy links — fast.
We pre-fill fields when possible to save you time.

🔍 Built for Transparency
Our dataset is continuously updated to reflect AI training disclosures, policies, and real-world findings — not just PR claims.

🧠 Private by Design
WTOM runs locally in your browser — no tracking, no data collection, no account required.

Why It Matters
AI companies are racing to harvest training data — often without permission, notice, or recourse. WTOM gives users a way to push back.
Whether you're an artist, researcher, student, or just someone who cares about data rights, you deserve to know who’s profiting from your activity — and what you can do about it.

What WTOM Covers
• Known and suspected data training domains
• Training disclosures and opt-out channels
• Protest tools and copy-paste language
• Live updates from our open-source config
• Future support for user-submitted domains
