Jan is an open‑source desktop application that provides a ChatGPT‑like experience running large language models locally. It includes a GUI, a CLI agent, and an OpenAI‑compatible local API server.

Use cases

• Chat with a local LLM without internet connection
• Run a private AI assistant for coding, writing, or research on your own machine
• Integrate a local LLM into custom applications via the built‑in OpenAI‑compatible API
• Use the Jan CLI agent to automate file editing, command execution, and web searches
• Experiment with different open‑source models and switch between them easily

When to choose

• You need full control over your data and want offline AI capabilities
• You prefer a single package that offers both a GUI and a CLI for AI tasks
• You want to run open‑source LLMs on Windows, macOS, or Linux without cloud fees
• You need an OpenAI‑compatible endpoint that runs locally for private applications

When to avoid

• You require enterprise‑grade scalability or multi‑node deployment
• You need GPU‑accelerated inference on Windows without additional setup
• You prefer a cloud‑only solution with managed model updates
