# SigmaOS A Mac browser for organizing tabs, working across pages, and researching with contextual AI. - Findings24: - 网站: - 价格: Freemium - 分类: AI 智能助理, 效率工具 ## 什么是 SigmaOS？ SigmaOS is a web browser for Mac built around organizing browsing into workspaces and task-like tabs. It combines vertical tab lists, split-screen browsing, keyboard shortcuts, and page-focused controls with Airis, an in-browser assistant that can answer questions about the page or search the web. Its core purpose is to make it easier to manage multiple browsing tasks and find information without losing track of open pages. ## SigmaOS 能做什么？ ### Workspaces and vertical tabs Organize pages into separate workspaces, with open tabs shown in vertical lists for a clearer overview. ### Task-like tab controls Mark tabs as done when finished or lock them to keep them available. ### Split Screen View two websites at once when a task requires comparing or using pages side by side. ### Airis page assistance Ask questions about the website you are viewing, find information in your own words, or request an explanation of a paragraph in context. ### Airis web search and summaries Ask Airis to search the internet and assemble a starting point from multiple pages, or simplify a website into an interactive summary with follow-up questions. ### Focus and browsing controls Hide browser interface elements with Focus Mode, preview links without opening them, and use the built-in ad blocker. Magic Theme adapts SigmaOS colors to the current website. ### Lazy Search and keyboard navigation Press Space to search pages, workspaces, commands and the web. Single-key shortcuts mark pages done, open workspaces and enter Focus Mode. ## 使用场景 ### Separate work and personal browsing Keep different projects or contexts in separate workspaces, and use separate profiles to sign in to different accounts within a workspace. ### Research a topic across sources Use Airis to search the web, read across multiple pages, ask follow-up questions, and create a starting point for further research. ### Read and compare pages Place two websites side by side with Split Screen, or ask Airis about the page currently open when you need a contextual explanation. ### Keep browsing tasks manageable Treat tabs as a lightweight task list: mark completed pages as done and lock pages that need to remain accessible. ## 常见问题 ### Which platform is SigmaOS for? SigmaOS is available on macOS. ### Can I bring data over from another browser? The migration tool imports cookies, active tabs, history and compatible extensions; bookmarks become tags. Stored passwords use a separate import step. ### How do separate accounts work? Enable Separate Profiles, called separate cookies in the workspace settings, to use different account sessions for the same website. You can organize work and personal contexts into different workspaces. ### What can Airis do? Airis answers questions about the current page, explains passages, searches the web and creates interactive page summaries with follow-up questions. ### Is there a free version? Yes. The free Personal/Basic tier includes the browser, unlimited workspaces, an ad blocker and limited Airis use. Paid Pro and Max memberships increase AI access; Max includes unlimited Look it up queries and interactive summaries. ## 快速信息 - **Product category**: Web browser - **Platform**: Mac - **AI assistant**: Airis - **Pricing model**: Free Personal/Basic browser with limited Airis; paid Pro and Max AI upgrades - **Notable workflows**: Workspaces, vertical tabs, task-like tabs, split-screen browsing
