Jan

Overview

Jan is an open-source AI platform for running language models locally and working with both local and cloud AI providers from a desktop interface. Local models can run directly on supported hardware, allowing private and offline inference without requiring a cloud account.

Beyond chat, Jan includes model management, an OpenAI-compatible local API server, projects, assistants, MCP integrations, and agent-oriented workflows. Developers can use Jan as a GUI for local models, expose those models through an API for other applications, or connect external coding and automation tools to locally hosted inference.
