Smart Groups is a Chrome add-on designed to enhance your browsing experience by automatically organizing open tabs into categories based on their domains. This tool addresses the common issue of tab clutter, which can arise when users browse multiple websites simultaneously. By analyzing the domains of open tabs, Smart Groups creates organized groups, similar to folders on a mobile device, allowing for a cleaner and more efficient browsing environment.

Key features of Smart Groups include automatic categorization of tabs by domain, alphabetical sorting of groups for easy access, and the ability to collapse unused groups to streamline the tab bar. Additionally, it prevents duplicate tabs by replacing newer tabs with older ones from the same domain. This functionality not only simplifies navigation but also maintains a tidy workspace for users who frequently juggle multiple tabs.
