Jan is your open-source, local AI powerhouse: run large language models (LLMs) like Llama and Mistral entirely offline for maximum privacy and data control.

Jan delivers a complete, open-source AI platform, positioning itself as a direct replacement for cloud-dependent services (e.g., ChatGPT). The core product, Jan Desktop, operates 100% offline on macOS, Windows, and Linux, ensuring your conversations and data never leave your device. It supports a hybrid model approach: run open-source LLMs like Llama and Mistral locally, or seamlessly connect to powerful cloud APIs (OpenAI, Groq) via API keys. The suite extends to Jan Server for private, on-premise infrastructure and a Web/Mobile roadmap, offering a full, customizable, and privacy-first AI stack.
