Description

Alternative to Arc's Sidebar, Dia's Sidebar, Edge's Vertical Tabs, Brave's vertical tabs panel, Vivaldi Windows Pane, Zen browser sidebar.

The missing Vertical tabs manager for Chrome.

It allows you to have more control over your web browsing experience by effectively managing multiple tabs at once.

๐Ÿค– Your AI Agent for Smart Browsing

Research, summarize, and organize, less talk, more action . Side Spaceโ€™s contextual AI works inside your side panel to automate your workflow.
