Side Space Overview
Side Space is a sophisticated browser extension designed to revolutionize your web browsing by tackling the pervasive issue of tab clutter. It functions as an AI-powered vertical tabs manager, neatly organizing all your open tabs into a dedicated side panel. This approach, inspired by the efficiency of browsers like Arc and Microsoft Edge, frees up horizontal screen space and provides a clear, manageable overview of your browsing session. The core concept revolves around 'Spaces'—distinct, customizable categories for different aspects of your life, such as work, personal projects, research, or hobbies. This compartmentalization allows you to focus on one context at a time, significantly reducing distractions and boosting productivity.
The standout feature of Side Space is its intelligent, AI-driven tab grouping. Instead of manually sorting through dozens of tabs, you can let the AI analyze your open pages and automatically organize them into relevant groups based on content or domain. This not only cleans up your workspace in seconds but also helps you discover connections between your browsing activities. Furthermore, Side Space is built for the modern user, offering seamless cloud synchronization. Your carefully curated Spaces and tabs are automatically saved and synced across all your Chrome browsers, ensuring you can pick up right where you left off on any device.
How to use Side Space
Getting started with Side Space is straightforward. First, you need to install the browser extension from the Chrome Web Store. Once installed, a side panel will appear in your browser (its position can be customized to the left or right in Chrome's settings). You can immediately begin organizing your current tabs. Use the 'Group by AI' feature to let the extension automatically sort your open tabs into logical groups. You can then create 'Spaces' to house these groups. For example, create a 'Work' space for all your job-related tabs and a 'Shopping' space for e-commerce sites. Switching between these Spaces is seamless, allowing you to change your focus with a single click or a two-finger swipe. The dedicated 'Spaces Management' page provides a centralized hub to rename, reorder, customize icons and themes, or delete your Spaces. You can also drag and drop tab groups or individual tabs between different Spaces to refine your organization.
Core Features of Side Space
- AI-Powered Tab Grouping: Automatically organizes open tabs into logical groups based on content or custom categories, eliminating manual sorting.
- Spaces for Organization: Create separate, self-contained workspaces (Spaces) for different projects or contexts like work, life, and hobbies to maintain focus.
- Vertical Tab Management: Displays tabs vertically in a side panel, making them easier to navigate and manage, especially with a large number of tabs.
- Cross-Device Sync: Automatically saves and syncs all your Spaces and tabs across any Chrome browser where you're logged in, ensuring your setup is always accessible.
- Memory Management: Includes a feature to suspend inactive tabs, freeing up system memory and improving browser performance.
- De-duplicate Tabs: Automatically detects and closes duplicate tabs to keep your workspace clean and efficient.
- Advanced Management Tools: Features include a powerful fuzzy search to find any tab or space, the ability to pin important tabs, save/restore tab groups, and customize themes, including a dark mode.
- Group Guard Settings: Allows users to create custom URL grouping rules for more precise and personalized tab organization, complementing the AI grouping.
Use Cases for Side Space
Side Space is ideal for anyone who regularly finds themselves overwhelmed by too many browser tabs. This includes students conducting research across multiple sources, professionals managing various projects simultaneously, and developers who need to keep documentation, forums, and development environments open. For users who admire the organizational structure of the Arc browser but prefer to stay within the Chrome ecosystem, Side Space serves as an excellent replacement. It's also perfect for 'serial multi-tabbers' who need an efficient way to save and restore entire browsing sessions without losing their workflow. By creating distinct Spaces, a user can dedicate one to 'Morning News', another to a 'Q3 Marketing Project', and a third to 'Vacation Planning', keeping each context separate and focused.
Advantages of Side Space
The primary advantage of Side Space is its ability to bring order to chaos, transforming a cluttered tab bar into a streamlined, productive workspace. The vertical layout is inherently more scalable than a traditional horizontal tab bar, preventing tab titles from becoming unreadably small. Its AI grouping feature is a significant time-saver, performing organizational tasks that would be tedious to do manually. Unlike some native browser solutions, Side Space offers robust cross-device synchronization, a critical feature for users who work on multiple computers. The ability to suspend tabs directly addresses browser performance issues, making it a practical tool for users on less powerful hardware. Finally, its freemium model with a generous free tier and an affordable lifetime deal makes powerful tab management accessible to everyone.
Pricing and Plans
Side Space offers a simple and transparent pricing structure:
- Free Plan: This plan is available at no cost and is perfect for getting started. It includes the ability to create up to 5 Spaces with cloud sync, AI grouping for up to 1000 URLs, and basic support.
- Lifetime Plan: For power users and 'tab hoarders', this is a one-time payment of $39. It unlocks unlimited Spaces, unlimited AI grouping, all advanced features like Tab Group Guarding and Space Management, lifetime premium support, and all future updates.
