Jan is a desktop app for people who want to run AI models on their own computer or connect to online models from one place. The homepage shows a model picker with open models and hosted options such as ChatGPT, Claude, Gemini, Llama, Mistral, Qwen, DeepSeek, Gemma and Kimi. It is free and open source, and the project reports more than six million downloads and 44.9K GitHub stars. A memory feature that carries context across sessions is marked as coming soon, so it is not available yet. The page lists a download for Mac only, so support for other systems is not confirmed. There is no pricing page and no statement about accounts, so sign-up requirements and paid plans are unknown. The homepage does not describe an API, so that is also unknown.
