Seems like a cool idea—I'm always game to try new operating systems! Recently been playing around with Playbit (https://playbit.app/)

Pneuma reminds me a little bit of Yansu AI, a project I saw recently on HN that proactively builds apps with AI (https://yansu.app/)

Thanks! Playbit is a cool project, I've followed it. The key difference with Pneuma is that the programs themselves are AI-generated at runtime. There's no toolchain the user interacts with, no editor, no compiler invocation. You describe what you want and the system handles everything from code generation through compilation to execution in one pass. Yansu is interesting too but it's a web app builder. Pneuma runs native GPU-rendered agents in WASM sandboxes on the desktop, so you can build things like real-time games and data visualizers with keyboard/mouse input, not just web UIs. The closest analogy is probably a microkernel where every userspace process is conjured by an LLM instead of installed from a package manager.
