What it does

SigmaOS is a browser that organizes tabs into workspaces and vertical lists, treating open tabs like to-do items that can be completed or locked. It includes Airis, an AI companion that can answer questions about the current page, search the web, and summarize content into short interactive digests.

How to use: Download and install SigmaOS on macOS. Organize tabs into workspaces, use vertical tabs for easy navigation, split screen for multitasking, and leverage Airis for website-specific information and summaries. Customize the browser with themes and shortcuts.
