Side Space 2.0

#1 AI Assistant for Your Tabs

2025-11-22

Product Introduction

  1. Side Space 2.0 is a browser extension that transforms the browser's side panel into an AI-powered vertical tabs manager, enabling users to organize, summarize, and interact with open tabs through natural language commands. It integrates an AI Assistant (Side Copilot) to automate browser tasks, manage tab groups, and provide contextual insights based on active tabs.
  2. The core value lies in streamlining tab management for productivity-focused users by reducing clutter, enabling cross-browser synchronization, and leveraging AI to automate repetitive workflows like tab grouping, research, and content extraction. It prioritizes spatial organization and context-aware automation to enhance browsing efficiency.

Main Features

  1. AI-Powered Vertical Tabs Management: Organizes tabs vertically in a collapsible side panel with AI-driven grouping, summarization, and deduplication. Users can chat with Side Copilot to extract information from open tabs, generate summaries, or request actions like closing duplicates.
  2. Context-Aware Browser Automation: Side Copilot operates in Agent Mode to automate tasks such as grouping tabs by domain or custom categories, restoring closed windows, arranging tabs in grids, and generating daily wrap-ups of browsing activity. It executes commands like "research topic" or "merge windows" using AI analysis of tab content.
  3. Cross-Browser Space Synchronization: Syncs tab groups (Spaces) across Chrome, Edge, Firefox, Brave, and niche browsers like Comet or Zen via cloud storage. Spaces retain themes, pinned tabs, and AI-generated categories, ensuring seamless transitions between devices without manual setup.

Problems Solved

  1. Eliminates Tab Overload: Addresses chaotic tab sprawl by auto-grouping tabs into thematic Spaces (e.g., work, shopping, study) and suspending inactive tabs to free memory. Reduces manual effort in managing 100+ tabs across multiple windows.
  2. Targets Multitasking Professionals: Designed for researchers, developers, and students juggling concurrent projects who need quick access to context-specific tabs and AI-assisted summarization for faster decision-making.
  3. Enables Cross-Device Workflows: Solves fragmentation in workflows by syncing Spaces across browsers and devices, allowing users to resume tasks seamlessly while maintaining AI-generated tab structures and shortcuts.

Unique Advantages

  1. Dual-Mode AI Integration: Combines Chat Mode (contextual Q&A about open tabs) and Agent Mode (action-oriented automation) unlike single-function competitors. Supports BYOK (Bring Your Own Key) to integrate custom AI models (e.g., GPT-4) for personalized automation.
  2. Vertical Tab Innovation: Extends beyond basic vertical tab managers (e.g., Edge) with AI-driven features like auto-theming, fuzzy search, and one-click AI grouping based on user-defined categories. Integrates memory-efficient tab suspension and deduplication.
  3. Cross-Platform Compatibility: Supports niche browsers like Comet and Zen, unlike rivals limited to Chrome/Edge. Offers lifetime licenses with free updates, contrasting subscription-based tools like Toby or Workona.

Frequently Asked Questions (FAQ)

  1. How does the product work? Side Space installs as a browser extension and occupies the side panel, where it displays vertically stacked tabs grouped into Spaces. The AI Assistant analyzes tab content to enable commands like summarization, tab grouping, and cross-window automation via natural language input.
  2. Is there a free version available? The free tier supports up to 5 Spaces, basic AI Chat for current pages, and limited tab grouping. Paid plans unlock Agent Mode, unlimited Spaces, and BYOK integration for advanced users needing custom AI models.
  3. What is BYOK (Bring Your Own Key)? BYOK allows users to input their API keys for AI services like OpenAI, bypassing Side Space’s default models. This ensures data privacy and cost control while retaining access to Agent Mode’s automation features.
