Jan
Free, open-source desktop AI assistant that runs entirely on your own hardware with no cloud dependency.
About
Jan is a locally hosted AI client that works as a privacy-focused alternative to cloud chat tools. It runs open-source models directly on your machine and also lets you connect to online providers such as Claude, ChatGPT, Gemini, or Mistral if you prefer. All conversation data stays on your device, and no subscription or API key is required to use local models. The application is free and open-source, available for Mac, Windows, and Linux.
