I. Basic Information
SigmaOS is a WebKit-based AI browser designed for users who frequently work on the web. It emphasizes a workspace-centric organization, compatibility with Chromium extensions, and deep integration with native macOS. The product incorporates the Airis AI assistant and A1Kit capabilities, enabling intelligent functions such as page understanding, interactive summarization, and querying, aiming to facilitate multitasking browsing and content creation within a single window. Currently, SigmaOS offers both free and paid versions, providing different AI usage limits and feature packs for individual and advanced users.
II. Product Overview
SigmaOS reimagines the browsing experience with a "one window, multiple workspaces" approach. Users aggregate pages and web applications into workspaces by project, task, or theme, replacing traditional multi-tab functionality with sidebar lists. Combined with split-screen and session management, it reduces page stacking and context switching costs. The browser uses the WebKit rendering engine, inheriting high performance and energy efficiency, and employs a self-developed mechanism to suspend long-term inactive pages to save memory. SigmaOS also supports mainstream extensions from the Chrome Web Store, meeting common needs such as password management, proofreading, and productivity automation.
