Jan

Jan is a free, open-source desktop application for running large language models (LLMs) locally on your own machine. It provides a clean, user-friendly interface to chat with AI models while keeping your data private and offline. Jan supports a wide range of models, including popular open-source options like Llama, Mistral, and Qwen, as well as online models from OpenAI, Anthropic, and Google. It features web search capabilities, model benchmarking, and soon a memory feature for persistent context. Built in public on GitHub with over 41K stars, Jan is designed for both technical and non-technical users who want control over their AI interactions without relying on cloud services.
