Life is a multisite app, an app that is not tied to any specific web apps/websites. So you can run and organize multiple web apps in a single window as independent workspaces which you can switch between easily using keyboard shortcuts. Each workspace is sandboxed, protecting you from cross-website trackers and preserving your privacy.
For example, you can keep all the web apps that are related to your personal life in the Life app. And then keep your work or school apps elsewhere (for example, Work or School app). It’s a great way to stay organized and achieve work-life balance.
