Side Space 2.0

#1 AI Assistant for Your Tabs

Overview

What it is

Side Space is an AI-powered vertical tab manager extension that organizes multiple tabs in a side panel for seamless browsing. With Side Copilot built into the side panel, you can organize tabs, research pages, and automate actions using simple natural-language commands.

Intent

I need it when

Access organized tabs and spaces across multiple devices and browsers

Side Space syncs spaces and tab groups across devices via cloud login. Users can save their workspace organization on Chrome and restore it on Firefox, Edge, or Brave, maintaining consistent tab organization across their digital ecosystem.

Reduce browser memory usage and improve performance with many open tabs

Side Space includes tab suspension functionality that temporarily suspends inactive tabs to free up system memory, allowing users to maintain large numbers of open tabs without degrading browser performance.

Automate repetitive browser tasks like tab grouping, window management, and research workflows

Side Space's Agent Mode enables AI-powered automation to handle browser actions autonomously—grouping tabs, managing windows, searching history, and researching topics. Users can ask the AI copilot to perform complex workflows, reducing manual tab organization and enabling hands-off browser management.

Organize and manage excessive open browser tabs without switching to a new browser

Side Space provides vertical tab management in a side panel, allowing users to organize tabs into named spaces (Workspace, Social Media, Shopping, etc.), group tabs by domain or AI-powered categories, and switch between spaces while staying in their current browser. This solves tab clutter without requiring migration to Arc, Edge, or other specialized browsers.

Chat with and extract information from multiple open tabs simultaneously

Side Space's Chat Mode allows users to interact with an AI copilot that understands the context of open tabs. Pro+ users can chat with multiple tabs at once, summarize content, extract data, and ask questions about their browsing context without leaving the browser.

Drop

Not a fit when

  • User needs Safari browser support; product only supports Chrome, Edge, Firefox, Brave, Vivaldi, and other Chromium-based browsers
  • User requires mobile or tablet app functionality; product is browser extension only
  • User needs semantic search across page content; product focuses on tab management and grouping, not full-text page search
  • User wants standalone application; product requires browser integration and cannot function independently
  • User needs real-time collaboration features; product is single-user focused with cloud sync for personal devices only
