NiahOS is a Portable OS that sits above the devices you already own. Instead of recreating accounts, files, and permissions in every app, NiahOS keeps identity, data, work, social, media, and AI in one governed environment—and carries that same desk from phone to tablet to laptop to desktop (and beyond). Open NiahOS on iPhone, Android, Mac, Windows, Linux, or the web and pick up where you left off: the same apps, files, messages, meetings, and people follow your account. Built-in capabilities cover messaging and calls, email and calendar, documents, spreadsheets and presentations, media libraries, social networking, file storage, and AI assistance—composed on one foundation rather than bolted together as separate SaaS silos. NiahOS is designed for both personal and organizational use. Global is the free personal Portable OS. Workspaces add business and enterprise controls such as SAML SSO, enforced MFA, admin management, dedicated hosting options, and tenant isolation.
