It's a tab extension for Google Chrome that loads some predefined tabs on startup, which is a previously available feature in the browser. It allows you to create an unlimited number of tab groups that you can load right upon opening the application.

If you have a group with three tabs, you can easily swap between them with just one click. You can even assign different keyboard shortcuts to each one. And if you create more groups, you can open a new one by dragging the group's title from the tab bar.

The installation process is pretty easy. Just go to the settings page and check the tab extension. After the installation, you need to go to the settings page and configure it to your needs. You need to add the tabs that you want to be loaded on startup, and it's that simple.
