SigmaOS is a new AI-enhanced web browser designed to optimize online work. Equipped with a unique Workspace feature, it organizes tabs into separate lists, like rooms in a house, enabling users to efficiently manage tasks by grouping tabs and marking them as complete. The browser supports vertical tab arrangements, split-screen multitasking, and ad-free browsing. A significant innovation is the browser assistant, Airis, facilitating searches, understanding web content contextually, and simplifying web pages. SigmaOS integrates popular Chromium extensions, ensures security with WebKit engine and Apple Keychain, and offers cross-device sync on macOS, optimized for performance and energy efficiency.
