OmniShield

About

While most AI tools focus on improving your interaction with AI, OmniShield prevents you from accidentally sharing secrets with it. Unlike extensions that manage chats or add sidebars, this tool conceals sensitive data right before it is sent from your browser, working within platforms like ChatGPT, Claude, Gemini, and Cursor. All processing occurs on your device with no prompts uploaded. It automatically removes API keys, environment dumps, JWTs, and emails prior to transmission. The core masking feature is free, while the Pro version includes OCR, healthcare pattern detection, and a blocking mode. Where other products aim to enhance your AI assistant, OmniShield acts as a safety belt for your AI usage.
