Visit SigmaOS

SigmaOS doesn’t just feel like a new browser—it feels like a new way to use the internet. After testing it, the AIChief team was struck by how intentional every feature is: vertical tabs, task-based workspaces, split-screen browsing, and a built-in AI assistant that understands your context. It’s built for people who juggle tabs and tasks like pros. If Safari is a car and Chrome is a truck, SigmaOS is a race-ready workspace. It’s ideal for researchers, creators, developers, and deep thinkers who want to move fast, stay focused, and reclaim the tab mess.

Accessibility

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.
