# AI Agent takes action for you

Manage tabs and windows, automate tasks, summarize and research, all from an Arc-style vertical tabs sidebar.

## Side Copilot

Vertical Tabs, Spaces, and AI Agent for Chrome

An 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 from your browser side panel. Side Copilot helps 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.

## Key Features

### Vertical Tabs Sidebar for Chrome

Create separate Spaces for work, study, research, shopping, reading, or side projects. Keep different contexts organized without losing your place.

### Save, Restore, and Reorder Tabs

Save sessions, restore tabs and tab groups, and reorder everything with drag and drop.

### Sync Across Browsers and Devices

Sign in once to sync your Spaces across Chrome and compatible browsers, so your tabs stay available wherever you work.
