Pneuma is a desktop computing environment with no pre-installed applications. You describe what you need and a working program appears in seconds. Want a CPU monitor? A game? A data visualizer? Just type it. Under the hood, your prompt generates a Rust program that compiles to WebAssembly and runs in a GPU-rendered sandbox (Vulkan/Metal/DX12). Agents persist, communicate with each other via IPC, and can be shared through a community store.
