  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.
  
  🤖 Your AI Agent for Smart Browsing
  
  Research, summarize, and organize, less talk, more action . Side Space’s contextual AI works inside your side panel to automate your workflow.
  
  🚀 Vertical tabs manager lives in your browser
  
  Enabling the vertical tabs setting moves your open tabs from the top of your browser window (above the address bar) to the left side of the window. This allows the tabs to be displayed vertically, stacked one on top of the other, instead of horizontally.

  👍 The advantages of vertical tabs
  
  Vertical tabs are an effective solution for avoiding clutter in your browser window and maximizing your on-screen space. Additionally, they enhance tab visibility for easier identification.
  
  PS: Side Space is a futuristic vertical tab manager that can only be used with Chrome version 114 or above.

  Side Copilot – Vertical Tabs, Spaces & AI Agent for Chrome
  
  Alternative to Arc Sidebar, Dia's Sidebar, Edge Vertical Tabs, Brave vertical tabs, Vivaldi Window Panel, and Zen Browser sidebar.
  
  Side Copilot is an Arc-style vertical tabs sidebar for Chrome with an AI agent that helps you organize tabs, manage windows, summarize content, and automate browsing workflows.
  
  If Chrome’s default tab bar feels messy, Side Copilot gives you a cleaner way to work. Move tabs into a sidebar, organize them into Spaces, sync them across browsers, and use AI to take action on your browsing context.
  
  🌍 Browse less, more action
  
  Research, summarize, organize, and take action, browse less, more action.
  
  Side Copilot works inside your browser side panel to help you manage tabs and windows, group related pages, search browsing history, summarize open tabs, chat with files, and automate repetitive browser workflows.
  
  ⸻
  
  🤖  Why Side Copilot?
  
  Chrome still lacks a native vertical tabs experience that feels complete. Side Copilot fills that gap with a fast, focused sidebar designed for people who live with dozens of tabs open.
  
  Whether you are a student, marketer, developer, creator, designer, or researcher, Side Copilot helps you reduce tab clutter and stay in control of your workspace.
  
  ⸻

  ⸻
  
  💅 Made for modern browsing
  
  Side Copilot combines:
  - vertical tabs manager
  - tab session organizer
  - Spaces workspace
