SigmaOS

SigmaOS is a modern web browser for macOS designed to enhance productivity and organization. Built on WebKit (like Safari), it supports Chrome extensions for flexibility. The browser features workspaces for grouping tabs, vertical tabs resembling a to-do list, split-screen multitasking, and a built-in ad blocker. SigmaOS includes an AI assistant called Airis that allows users to chat with web pages, search using natural language, summarize content, and simplify pages into interactive summaries. Additional features include lazy search (quick search by hitting spacebar), command-hover for link previews, magic theme to match website colors, and focus mode for distraction-free reading. SigmaOS uses the A1 Kit, an AI browser engine that understands page context to assist with tasks.
