What is Jan?

Jan is a really cool, open-source alternative to ChatGPT. What makes it special is that it lets you interact with AI right on your own computer, completely offline. It’s built to be super customizable, so you can really make it your own for secure, private chats. Everything you do – your conversations, your settings – stays right there on your machine. The whole development process is out in the open on GitHub, which shows a big commitment to open-source AI. You get features like working offline, that public GitHub development, AI assistants you can tweak, compatibility with OpenAI’s API, and handy tools like global hotkeys and inline AI to make your work smoother. Since Jan is still being developed, you might run into a few bugs here and there. But, it does offer an API server at localhost:1337 that acts just like OpenAI’s API, making it easy to connect with other apps that work with it. If you’re a developer or just curious, you can easily check out the project’s roadmap, changelog, and documentation to see how it’s coming along or even contribute.
