SigmaOS — AI browser for organized productivity

SigmaOS is an AI-powered productivity browser for founders and professionals managing complex web workflows.

SigmaOS is an AI-powered browser that redesigns the browsing experience to function like a productivity operating system. This tool is built specifically for founders, researchers, and marketing professionals who manage dozens of open tabs and disparate web-based workflows daily. By replacing traditional horizontal tabs with vertical workspaces and a command-line interface, SigmaOS allows users to group websites by project rather than session. The platform includes Airis, an AI assistant that can summarize long-form articles, explain complex text, or rewrite content directly within any webpage. Business owners can benefit from the split-screen multitasking feature, which enables side-by-side comparison of data without toggling between windows. The browser also features global shortcuts and a "Lazy Search" function that navigates through tabs, history, and workspace files instantly. Verified on surfai.app in 2026, the browser significantly reduces the cognitive load associated with switching between SaaS tools. Its built-in ad blocker and focus mode minimize distractions during deep work sessions. Users can import their existing Chrome or Safari data to transition their entire digital office into this organized environment. SigmaOS offers a free version for individuals with more advanced workspace management available on paid tiers.
