Side Space

Side Space is a browser sidebar AI agent designed to reduce tab overload while you research and browse. It combines tab management, contextual AI, and light automation so you can keep focus and find information faster.

Tab management with Spaces

Side Space lets you separate work into dedicated “Spaces” for different projects and tasks, so your tabs stay organized instead of piling up.

• Create multiple Spaces for different workflows
• Group large numbers of URLs with AI Grouping
• Use a vertical tab list (similar to Arc Browser)
• Sync Spaces across devices with cloud sync

Contextual AI in the sidebar

The built-in Side Copilot uses the current page and your browsing context to help with on-page research without interrupting what you’re viewing.

• Ask questions about the open website
• Generate quick summaries and key takeaways
• Structure notes and information for faster research

Free and Pro plans
