Permission Sentinel is a Chrome extension that demystifies the permissions requested by other extensions. It translates technical jargon into clear, understandable language, allowing users to grasp the implications of each permission. The tool assigns risk scores ranging from Low to Dangerous based on the combination of permissions, helping users make informed choices before installation. Additionally, it warns users about potentially risky extensions directly on the Chrome Web Store.

Key features include smart risk assessments that highlight dangerous permission combinations and behavioral red flags, such as clipboard access or screenshot capture. The extension operates entirely offline, ensuring user privacy with no data collection or external API calls. With dark mode support and open-source availability, Permission Sentinel is an essential tool for anyone concerned about browser security and privacy.
