What It Is

SigmaOS is a new type of browser for macOS. Rather than positioning itself as traditional enterprise SaaS, it is more of a “work-focused AI browser” for individuals and knowledge workers. It rebuilds the browser workflow with Workspaces, vertical tabs, task-like tab management, and split screen, while also integrating the Airis AI assistant to help users ask questions based on web page content, explain passages, search the web, and generate interactive summaries.

Core Capabilities

The product centers on two areas: web page organization and AI assistance. Workspaces manage different tasks like “rooms,” while vertical tabs provide a to-do-list-like view where tabs can be marked as completed or pinned. Separate Profiles allow different workspaces to log in to different accounts, making it suitable for switching between personal and company accounts. Productivity features include Lazy Search, single-key shortcuts, Command-Hover link previews, Focus Mode, split screen, and ad blocking. Technically, SigmaOS uses WebKit and SwiftUI, emphasizing macOS performance, battery efficiency, and system integration. It also supports Chromium extensions from the Chrome Web Store, lowering the barrier for users migrating from Chrome.

Pricing

The free Basic/Personal plan can be used long term and includes unlimited workspaces, ad blocking, and limited Airis access. Personal Pro costs $20/month and provides unlimited Advanced Airis (GPT-4o), higher search usage, and interactive summaries. Personal Max costs $30/month and adds more LLM models such as Llama and Claude, along with unlimited searches and summaries. Paid plans come with a 14-day money-back guarantee, and students and educators can get 50% off Pro.

Pros and Cons

Its strengths are a well-designed browser workflow, making it suitable for handling multiple projects, multiple accounts, and large volumes of web-based research materials. Its AI capabilities are tightly integrated with page context, and support for Chromium extensions is a major highlight. The drawbacks are that it currently only supports macOS, with Windows and iOS still unavailable. Information on enterprise-grade team permissions, auditing, SSO, compliance certifications, and similar features has not been disclosed, so it should not be directly viewed as a mature enterprise browser management platform. Advanced AI features are also significantly more expensive than those of ordinary browsers.

Who It’s For and Access from China

SigmaOS is better suited to students, founders, creative professionals, researchers, and heavy browser users, especially those who rely on macOS and want to use AI to process web information. The text does not specify accessibility in mainland China, and its AI features may depend on external large model services, so actual availability should be verified through local network testing.
