Credit cards, passwords, API keys — AI Shield catches sensitive data before it reaches ChatGPT, Claude, or Gemini. 100% free. 100% local.
The Gap
Billions of people use AI tools daily. Not a single product protects consumers from data exposure — until now.
Every prompt, every paste, every upload is stored and potentially used for training. Your sensitive data becomes part of the model.
Adversarial prompts hidden in documents and web pages can trick AI systems into leaking your private information.
Existing AI security products are built for corporations. They require IT teams, contracts, and budgets most people don't have.
No browser extension. No free tool. No simple solution. Everyday users were completely exposed when using AI.
Simple Setup
Three steps. Thirty seconds. Full protection.
One click from the Chrome Web Store. No account, no configuration, no permissions to manage.
Keep using ChatGPT, Claude, Gemini, and every other AI platform exactly as you do today.
AI Shield silently scans your input and warns you when sensitive data or prompt injection threats are detected.
Capabilities
Catches credit cards, SSN, emails, phone numbers, IBAN, and API keys before they leave your clipboard.
Detects adversarial prompts designed to manipulate AI systems and extract your private information.
Scans documents for sensitive data before you upload them to any AI platform.
