BlurShield is a Chrome add-on designed to enhance screen privacy for developers by automatically detecting and blurring sensitive information such as API keys, tokens, and private URLs. Operating entirely within the browser, it ensures that all scanning is local, meaning no data is transmitted to external servers. This makes it an excellent tool for those who frequently share their screens during meetings or presentations.

Key features include real-time detection of over 55 secret patterns through local regex matching, a 'Meeting Mode' panic button for immediate privacy, and a 'Leak Preview' function to visualize what will be shared. Additionally, users can create custom blur zones, utilize a Clipboard Guard for added security, and define their own regex patterns for internal secrets. The seamless integration with all websites and the absence of configuration requirements make BlurShield a user-friendly choice for maintaining privacy.
