Jan is a free, open-source AI chat application that runs entirely on your local machine. Unlike cloud-based tools like ChatGPT, Jan sends no data to external servers — all inference happens on-device using local language models including LLaMA, Mistral, and other GGUF-format models. It supports Mac, Windows, and Linux and works fully offline. Jan is the go-to choice for developers and privacy-conscious users who want a self-hosted AI assistant with complete data sovereignty.
What Is Jan AI?
Jan is a free, open-source desktop application that runs large language models (LLMs) entirely on your local machine — no internet required after the initial model download. It supports Llama 3, Mistral, Phi-3, and other open models, and stores all conversations locally with zero telemetry.
Does Jan AI Work Offline?
Yes. Jan runs 100% offline after downloading a model. No data is sent to any cloud server. It works on Mac, Windows, and Linux, and is designed for users who need privacy-first AI without API costs or usage limits.
