About SigmaOS

SigmaOS is a web browser designed to organize browsing into workspaces, similar to rooms in a house. Tabs are displayed vertically and can be treated as tasks that are marked done or locked. The browser includes a split-screen feature for viewing two websites simultaneously.

The browser includes Lazy Search, which allows users to search tabs, the internet, commands, and bookmarks by pressing the spacebar. It also features an AI companion called Airis that can chat with websites, find information using natural language, and explain paragraphs in context.
