AI Paste Guard is a Chrome extension designed to protect sensitive data from accidental exposure during interactions with AI tools. This free add-on acts as a security barrier, scanning clipboard pastes in real-time to prevent the leakage of API keys, tokens, and credentials. It detects a wide range of sensitive data, including cloud credentials, developer secrets, API tokens, and personally identifiable information (PII), ensuring that your organization’s security remains intact while using AI platforms.

The extension operates seamlessly across major AI tools like ChatGPT, Google Gemini, and Microsoft Copilot, providing robust protection without requiring any setup. AI Paste Guard processes all data locally, ensuring privacy by not logging the content of your clipboard, only recording instances of detected violations. As an open-source tool, it allows users to verify its functionality, making it a reliable choice for developers looking to enhance their security practices.
