Jan is an open-source desktop application that lets you run AI language models locally, offering a private and offline alternative to cloud-based chatbots like ChatGPT. Core capabilities include selecting from hundreds of open models (e.g., Llama, Mistral, DeepSeek) or connecting to online APIs like OpenAI, with a clean minimal interface and optional memory that carries context across sessions. Perfect for developers, privacy-conscious users, and solopreneurs who need complete control over their AI interactions—ideal for coding help, drafting, research, or any task requiring confidential processing without internet dependency.
