About OmniShield
OmniShield is a browser extension designed to prevent accidental exposure of sensitive data such as API keys, passwords, and personally identifiable information (PII) when using AI chat interfaces like ChatGPT, Claude, or Cursor. It operates entirely on the user’s device, intercepting prompts before they are transmitted to AI providers and replacing sensitive elements with safe placeholders. The tool supports detection of over 100 secret patterns, including OpenAI, AWS, GitHub, and Stripe keys, as well as emails, credit card numbers, and phone numbers. Free users receive basic pattern-based masking, while Pro users gain context-aware masking that preserves the structure and role of secrets, enabling AI models to reason about requests without seeing the original values. Pro also includes features like on-device OCR scanning, healthcare pattern detection for HIPAA compliance, and custom detection rules. The extension is installed via the Chrome Web Store and functions without requiring an account or uploading prompts to external servers.

How does the Pro version differ from the Free version?
The Pro version offers context-aware masking, which preserves the structure and role of secrets so AI models can still reason about requests without seeing the original values. It also includes on-device OCR scanning, healthcare pattern detection, block mode, and custom detection rules.
What integrations does OmniShield support?
OmniShield works with AI chat interfaces such as ChatGPT, Claude, Gemini, Perplexity, and Cursor. It integrates directly into the browser via a Chrome extension and does not require additional software or APIs.
