Jan (jan.ai) Review
Jan is a free, open-source desktop application for running AI models locally on Windows, macOS, and Linux. Users can download and chat with open-weight models from Hugging Face, with conversation data stored on-device for privacy. Jan also provides a local OpenAI-compatible API server, so other applications and scripts can call local models through a familiar interface. The app handles model management, GPU and CPU inference settings, and thread history, making it a self-contained alternative to cloud chat services for users who want offline, private AI access without per-message costs.
