About Jan

Jan is a free, open-source desktop chat app that runs open models such as Llama, Qwen and Gemma fully offline on your computer. You can also plug in online models by adding your own API key for providers like OpenAI, Anthropic, Google, Mistral or DeepSeek, and switch between local and cloud models in the same app.
