A new desktop operating system aimed at people who live inside AI tools has been announced, and its makers want it to compete with Windows. The system, Kora OS, was shown on 10 November by Kora Systems. It runs on Linux and treats AI models and agents as part of the operating system itself, not as separate apps. Expect it on PCs in 2027 at no charge, with the company earning from subscriptions to AI models and services.
The company is led by Kirt McMaster, a co-founder of Cyanogen, the Android-based OS company that folded its OS business years ago. Kora grew out of Playtron, the company McMaster founded to build the Linux gaming OS GameOS; the company rebranded in July 2025 as it moved to AI. GameOS lives on inside Kora as a play mode that turns the desktop into a game console.
In its press release, Kora argues that Windows and macOS confine AI to a web page or a locked-down app, so it cannot see the files and programs around it. Its answer is Cortex, an engine that spreads AI work across a PC’s CPU, GPU and NPU, runs local models by default and brings in cloud models when needed. Each workspace is a sandbox for its apps and agents, with permissions the user controls and memory kept on the machine. An SDK will let outside developers use the same building blocks, such as memory, context, semantic search and email.
Kora’s target is narrow. Kora’s release says about 45 million people, roughly half a percent of the world, account for 80% of spending on AI, and that this could pass 150 million by 2033. These are the company’s estimates. Its OS is for those heavy users, the developers and creators who run agents and coding tools all day, not for every Windows owner.
In TechCrunch’s interview with McMaster, the CEO is quoted as saying “Microsoft can keep its billion users”. About 50 engineers build Kora with OpenAI’s Codex and Anthropic’s Claude and ship at least five times faster than before, according to McMaster. The system rests on Linux and Nix, replacing the Fedora Silverblue base used by GameOS. Kora’s own layers, Cortex and the desktop interface, remain closed even though the foundations are open source; no commitment has been made to open them up. Models from several vendors are meant to plug in. Android apps and AI tools for making games are on the roadmap.
On hardware, Kora is working with Qualcomm on Snapdragon PCs, including the Snapdragon X2 Elite, and it also supports Intel and AMD machines. A separate enterprise version, Humain OS, is being built with Saudi Arabia’s Humain for Snapdragon laptops in 2027. Backers include Samsung Next and Square Enix, and the company declined to give its total funding or valuation. Partnerships with PC makers are to be announced later, with no names yet, and there is no download, subscription price or supported-laptop list to look at.
