Jan AI

Draft a function, ask a question about a snippet of code, or rewrite an email, all without a single byte leaving your machine.

That is the pitch of Jan AI, an open-source ChatGPT alternative that runs 100% offline on your computer.

Jan AI is a local AI chatbot and assistant that uses open-source AI models, so the conversation stays on your hardware rather than on someone else's servers.

Privacy is the main reason to pick it, and customization comes second.

You choose which open-source models to run and adjust the setup to suit how you work.

Jan AI installs on Windows, Mac and Linux.

A mobile version is listed as coming soon, so for now it is a desktop tool.

Developers get something extra.

Jan AI provides an OpenAI-equivalent API server, which means you can run a local server and point your own apps or scripts at it using the same style of API calls you may already know.

That makes it a handy testing ground for coding projects that would otherwise depend on a paid cloud service.
