About Side Space
Side Space is a browser extension designed for heavy browser users, students, researchers, developers, and creators who need to manage numerous open tabs efficiently. It replaces the default horizontal tab bar with a vertical sidebar that includes fuzzy search, pinning, multi-select, and drag-and-drop tab and group management. Users can create Spaces to separate different contexts such as work, study, shopping, or hobbies, with customizable theming, renaming, ordering, and a space switcher for quick switching. The Side Copilot AI feature automates tab organization by grouping tabs based on titles, URLs, and page content, and offers chat and automation capabilities like summarizing pages, selecting context from open tabs, researching topics, searching browser history, restoring closed windows, and managing tab groups and windows. Additional tools include performance optimizations such as tab suspension to reduce memory usage, de-duplication of tabs, saving and restoring tab groups, copying all URLs in various formats, and session backup via JSON. The extension supports multiple browsers including Chrome, Edge, Brave, Firefox, and other Chromium-based browsers, with cloud sync available across devices. Side Space operates on a freemium model, offering a free tier with basic features and paid plans that unlock advanced AI capabilities, shortcuts, and additional tools like multi-tab chat, mind maps, YouTube chatting, and file chat.
