Jan on a Mac
Private, offline AI desktop app (OpenAI-compatible) · AI / LLMs
Jan is an open-source ChatGPT alternative that runs models 100% offline on your Mac. Its desktop app includes a local API server (OpenAI-compatible, default :1337) you can switch on in settings — add that in AI Models as a network endpoint to use Jan's models in the assistant.
