Pneuma reimagines the operating system as an AI-native experience. Instead of apps, files, and folders, everything is a conversation. The AI manages your data, runs tasks, and coordinates tools. It aims to replace the traditional desktop metaphor with a purely intelligent interface.

Open WebUI is a self-hosted ChatGPT-like interface for Ollama and other LLM providers. Multi-model support, RAG, web search, and document analysis.
Reviewer scorecard
“This is the most ambitious rethink of computing I have seen since the iPhone. Ditching the file-and-folder paradigm entirely for AI-first interaction is either visionary or insane — probably both. If even 20% of this vision works, it will influence every OS built after it.”
“Self-hosted AI interfaces will be standard for privacy-conscious users and organizations. Open WebUI leads here.”
“An OS with no filesystem, no apps, no traditional UX escape hatch? Brave, but I need to actually get work done. When the AI misunderstands my intent I want to fall back to clicking buttons, not argue with a chatbot. The developer story is also completely unclear — how do you build for this?”
“The best self-hosted chat interface for local LLMs. Multi-model, RAG, and plugin support in one package.”
“We have been promised "conversational computing" since Siri launched in 2011. Pneuma is a gorgeous demo but the gap between demo and daily driver is enormous. Latency, reliability, and the inability to do anything without AI mediation will frustrate power users within hours.”
“Deploy with Docker, connect to Ollama, and you have a private ChatGPT. The feature set is remarkably complete.”
