Arclight | Vertical Tabs

About

Arclight is the luxury upgrade for organized Chrome users. 

A stunning, forward-thinking sidebar helps you quickly see and organize tabs.  On-device AI auto-names your windows in realtime, and notices when a new tab should be in a different window.

Inspired by the Arc Browser, Arclight is the sidebar Chrome should have shipped with.
