PuPu

Your AI, your way — beautifully simple.

A desktop AI client for local and cloud models — workspace-aware chat and a built-in MCP tool store, in one clean native app.

PuPu is a cross-platform desktop AI client that lets you chat with local models through Ollama or connect to cloud providers such as OpenAI and Anthropic. It is built for people who want one fast desktop app for everyday AI work, not a browser tab maze.
