SigmaOS is a next-generation web browser designed for productivity, focus, and multitasking. It combines intuitive tab management (via vertical layouts), project-based workspaces, and unique features like Focus Mode, AI-powered contextual search, and real-time link previews.
Tabs are treated like tasks�sortable, lockable, and markable as �done.� Users can split the screen, work across logins, and collaborate across sessions. With a built-in AI assistant named Airis, SigmaOS also lets users chat with webpages, ask follow-up questions, and summarize content. It�s everything a power user needs, baked into one ultra-fast browser.
