If Chrome’s default tab bar feels messy, Side Copilot gives you a cleaner way to work. Move tabs into a sidebar, organize them into Spaces, sync them across browsers, and use AI to take action on your browsing context. 🌍 Browse less, more action Research, summarize, organize, and take action, browse less, more action.
