General Information

Jan is a ChatGPT-alternative that runs on your own computer, with a local API server. It uses open-source AI models, stores data in open file formats, and is highly customizable via extensions. Jan believes in the need for an open-source AI ecosystem. We aim to build infra and tooling to allow open-source AIs to compete on a level playing field with proprietary offerings.

💻 Own your AI
Jan runs 100% on your own machine, predictably, privately and even offline. No one else can see your conversations, not even us.

🏗️ Extensions
Jan ships with a powerful extension framework, which allows developers to extend and customize Jan's functionality. In fact, most core modules of Jan are built as extensions and use the same extensions API.

🗂️ Open File Formats
Jan stores data in a local folder of non-proprietary files. You're never locked-in and can do what you want with your data with extensions, or even a different app.

🌍 Open Source
Both Jan and Nitro, our lightweight inference engine, are licensed via the open-source AGPLv3 license.
