NiahOS

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.

nida-os

Nida is an AI-powered, white-label business platform built for people who want to start and grow their own digital marketing agency. Instead of piecing together separate tools for CRM, websites, lead generation, automation, scheduling, communications, reviews, payments, and client management, Nida brings everything into one platform that can be used to sell and deliver digital services to local businesses. Users can find and manage prospects, build websites and landing pages, capture leads, automate follow-up, schedule appointments, manage client communication, collect payments, monitor reviews, track performance, and organize client work from a single workspace. Nida is also designed to reduce the amount of technical knowledge needed to start an agency. Its AI-powered tools help users identify opportunities, recommend next actions, assist with prospecting and follow-up, and manage more of the day-to-day work involved in serving clients. Because Nida is white-label, users can build their own agency brand around the platform and offer services under their own name. Nida is ideal for aspiring agency owners, freelancers, consultants, and entrepreneurs who want a practical way to start selling digital marketing services without building an entire software stack from scratch.
