AI Safe Chat Guard

🛡️ 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, Copilot and more — 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 the AI's 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 (file upload scanning)
✓ Scans PDFs you DRAG AND DROP onto AI chat windows
✓ Fires an instant purple warning banner with details of what was found
✓ "Remove File" button clears the malicious document before it's sent

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

⚡ REAL-TIME INPUT PROTECTION

Instant warnings BEFORE you hit send:

🔐 Passwords — Never accidentally share credentials
🆔 Social Security Numbers — Blocked instantly
💳 Credit cards — Detected before sending
📧 Phishing emails — 95%+ detection accuracy
🧠 Prompt injection — Hidden AI hijacking commands

All warnings fire in under 100ms. Zero delay. Zero friction.

🔍 AI RESPONSE SCANNING

After the AI responds, we analyze the output too:

✓ Credential theft attempts — AI asking for your passwords or personal info
✓ Phishing patterns — Social engineering in AI responses
✓ Malicious code — Dangerous scripts hidden in code suggestions
✓ Blur overlay — Critical threats are hidden until you choose to reveal

- 100% local analysis — no external servers, ever
- No account required — install and go
