## Overview

- **Who it's for**: Developers, privacy-conscious users, and anyone who wants to run LLMs on their own machine instead of sending data to a cloud API — no account or internet connection required.
- **What you get**: A free, open-source desktop chat app (Windows, Mac, Linux) for running open-source LLMs (Llama, Mistral, Qwen, Gemma, DeepSeek, and others) locally. It includes a built-in, OpenAI-compatible API server so other apps can point at your machine instead of OpenAI's. You can also plug in cloud providers like OpenAI, Anthropic, or Gemini within the same interface if you choose to.
- **How it works**: Jan runs models locally using the llama.cpp inference engine, downloading open-weight models (GGUF format) to your computer so conversations and inference happen entirely offline, with no data sent to a server unless you explicitly connect a cloud model.
