🛡️ AI Safe Chat Guard — The AI Security Extension That Actually Protects You
While other "privacy" extensions were caught secretly harvesting millions of users' AI conversations and selling them to data brokers, AI Safe Chat Guard does the opposite. Everything runs locally on your device, no data ever leaves your browser, no account required, no exceptions.

THE PROBLEM WITH OTHER EXTENSIONS
In 2025, popular Chrome extensions marketed as "AI privacy tools" were caught intercepting conversations from ChatGPT, Claude, Gemini, and Copilot, then quietly selling that data to third parties. One extension with 8 million users and a Google Featured badge was doing this silently in the background. Another 30+ extensions disguised as AI assistants were found stealing API keys and personal data.
AI Safe Chat Guard was built as the antidote to exactly this. We protect you FROM AI threats,  we don't become one.


WHAT MAKES US DIFFERENT

Zero data collection. No account. No email. No servers.
All scanning happens locally in your browser. Nothing is transmitted.
Open about exactly what we do and how we do it.
No silent updates that change behavior. You stay in control.

WORLD'S FIRST: Prompt Injection Protection
The newest and most dangerous AI attack nobody is talking about:
Malicious documents and emails contain hidden instructions designed to hijack AI behavior. When you paste or upload that content, the AI follows the attacker's commands instead of yours — potentially asking for your passwords, SSN, or credit card.
AI Safe Chat Guard is the only consumer extension that detects and blocks these attacks:

Scans text you paste for hidden injection commands
Scans PDFs you upload before they reach the AI
Scans PDFs you drag and drop onto AI chat windows
Fires an instant warning with details of what was found
Clears the malicious document before it's sent

Real attack we tested: A fake Bank of America security notice with hidden white text instructing the AI to ask for your SSN and credit card. Caught instantly.

REAL-TIME INPUT PROTECTION
Instant warnings before you hit send passwords, social security numbers, credit cards, phishing content, and prompt injection commands. All warnings fire in under 100ms.

AI RESPONSE SCANNING
After the AI responds, we analyze the output too credential theft attempts, phishing patterns, malicious code hidden in suggestions. Critical threats are blurred until you choose to reveal them.
