防詐守衛 is a Chrome extension designed to enhance online safety by providing real-time assessments of website security. This tool automatically analyzes the safety status of websites as users browse, delivering visual notifications about the risk levels associated with each site. It helps users avoid potentially malicious websites, phishing attempts, and other suspicious content, making it an essential tool for secure browsing.

The extension evaluates websites based on their URLs, categorizing them into five risk levels: 'extremely high risk', 'high risk', 'medium risk', 'lower risk', and 'safe'. Users receive instant notifications in the top right corner of the browser, detailing the security status and risk level of the current site. For more in-depth analysis, users can click on the 'Learn More' button to access a detailed security report, which includes an AI-generated summary and risk assessment. Additionally, it offers options for safer browsing, such as the ability to close high-risk tabs directly.
