What Is Jan?
Jan is an open-source ChatGPT replacement built for people who want more control over how they use large language models. It lets you run local models on your own machine or connect cloud models like GPT, Claude, and others from one desktop workspace.
That makes Jan a strong fit for anyone who wants a cleaner local AI assistant workflow without handing every conversation to a single hosted provider. It works as a private daily chat app, a flexible model playground, and a simple bridge between local inference and API-based models.
Key Features of Jan
Jan stands out when privacy, model flexibility, and local-first AI workflows matter more than another locked-down chat app.
- Run open-source AI models locally on your own computer.
- Connect cloud providers like GPT and Claude from the same interface.
- Use an open-source desktop app instead of a vendor-locked chatbot.
- Switch between local and hosted models depending on privacy or speed needs.
- Keep more control over prompts, model selection, and everyday AI workflows.
Use Cases and Applications
Jan is most useful when a user wants one place to compare models, keep sensitive work local, or avoid building a custom interface from scratch.
