Who It's For

What Makes Jan Different

Unlike cloud-based AI assistants, Jan prioritizes your privacy and autonomy. It's fully open-source, meaning you can inspect, modify, and contribute to the codebase. The platform is built in public with an active Discord community and regular updates. Jan combines the convenience of modern AI chat interfaces with the security of local processing, making it ideal for sensitive work, personal projects, or anyone who simply prefers to keep their AI interactions private.
