After challenging Google’s Android with Cyanogen, its co-founder takes aim at Windows for AI era

Kirt McMaster's Kora Systems unveiled a Linux-based desktop operating system that builds AI models and autonomous agents into the system itself, letting them work across apps, access files and keep context between tasks. It's due in 2027, free to use, for Intel, AMD and Qualcomm Snapdragon PCs. Revenue is meant to come from subscriptions bundling AI models and agent services.

Windows held about 77 percent of the desktop market in October per StatCounter. Kora isn't chasing that whole base. McMaster is targeting the people who use AI heavily, a group he estimates at 45 to 50 million today and expects to top 200 million by 2033.

We think the core thesis is right. Agents confined to a browser tab or a single app hit walls fast. If an assistant is going to do real work, it needs access to files, applications and memory across tasks. An operating system is the natural place to grant that, and Kora's separate agent workspaces with restricted access are the right instinct.

That's also where the risk lives. An OS that lets autonomous agents roam across files and apps is a much bigger security surface than a chatbot. A bad instruction, a poisoned document or a compromised model could reach everything. The workspace restrictions will need to hold up under real attack, and we'd want independent security review before anyone trusts it with sensitive work.

The lesson McMaster draws from Cyanogen is sharp: compete with an incumbent while depending on them and you lose. Kora is building on Linux and Nix and supporting multiple model providers. But its Cortex AI engine and interface stay proprietary, and it depends on frontier models from the same companies building their own AI-native experiences. Independence from Microsoft doesn't mean independence.

The development story is notable too. A team of about 50 engineers says AI coding tools from OpenAI and Anthropic sped up its work at least fivefold, mostly in the past six months. That's McMaster's estimate, not an audited figure. If it holds, small teams taking on platform-scale projects becomes more realistic.

Our read: a credible team with real partners, Qualcomm and Saudi AI company Humain among them, but desktop OS history is a graveyard. Distribution through PC makers will decide this, and none have been named.

Kora was previously Playtron, a Linux gaming OS company that rebranded in July 2025, and it builds on nearly three years of that work. Its enterprise version with Humain, called Humain OS, is expected on Snapdragon laptops in 2027. Investors include Samsung Next, Square Enix, Alumni Ventures, Polychain, VanEck and Circle; the company declined to disclose total funding or valuation.
