OpsAI Shield

About

Your AI conversations are private. Keep them that way.

Every day, millions of people paste emails, phone numbers, credit card details, and passwords directly into AI chatbots — without thinking twice. OpsAI Shield catches that data before it ever leaves your keyboard.

🛡️ What OpsAI Shield does

OpsAI Shield sits quietly in your browser and scans everything you type or paste into AI tools. The moment it detects sensitive information, it stops the message and gives you the choice: send a masked version, send as-is, or cancel.

It also scans screenshots and images you share — redacting sensitive text directly on the image before it reaches the AI.

🔍 What it detects

- Emails — personal and professional addresses
- Phone numbers — all formats: (514) 555-1212, 514-555-1212, 5145551212
- Credit card numbers — with Luhn validation to eliminate false positives
- SIN / SSN — Canadian Social Insurance Numbers
- Street addresses
- Passwords — detected via keyword context (password:, pwd=, mdp:)

🖼️ Image & Screenshot Protection

Share a screenshot on ChatGPT? OpsAI Shield reads the text in your image using on-device OCR, detects any sensitive data, and blacks out those zones before the image is sent.

⚠️ Unprotected Site Warning
