       Show HN: I built an OS that is pure AI
        
       I've been building Pneuma, a desktop computing environment where
       software doesn't need to exist before you need it. There are no
       pre-installed applications. You boot to a blank screen with a
       prompt. You describe what you want: a CPU monitor, a game, a notes
       app, a data visualizer and a working program materializes in
       seconds. Once generated, agents persist. You can reuse them, they
       can communicate with each other through IPC, and you can share them
       through a community agent store. The idea isn't that everything is
       disposable. It's that creation is instant and the barrier to having
       exactly the tool you need is just describing it.  Under the hood:
       your input goes to an LLM, which generates a self-contained Rust
       module. That gets compiled to WebAssembly in under a second, then
       JIT-compiled and executed in a sandboxed Wasmtime instance.
       Everything is GPU-rendered via wgpu (Vulkan/Metal/DX12). If
       compilation fails, the error is automatically fed back for
       correction. ~90% first-attempt success rate.  The architecture is a
       microkernel: agents run in isolated WASM sandboxes with a typed ABI
       for drawing, input, storage, and networking. An agent crash can't
       bring down the system. Agents can run side by side, persist to a
       local store, and be shared or downloaded from the community store.
       Currently it runs as a desktop app on Linux, macOS, and Windows.
       The longer-term goal is to run on bare metal and support existing
       ARM64 binaries alongside generated agents. A full computing
       environment where AI-generated software and traditional
       applications coexist.  Built entirely in Rust.  I built this
       because I think the traditional software model of find an app,
       install it, learn it, configure it; is unnecessary friction. If a
       computer can generate exactly the tool you need in the moment you
       need it, and then keep it around when it's useful, why maintain a
       library of pre-built software at all?  Free tier available (no
       credit card). There's a video on the landing page showing it in
       action.  Interested in feedback on the concept, the UX, and whether
       this is something you'd actually use.

         | 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.
