Our Principles

Jan is opinionated software on what AI should be

Local-first

We believe your conversations and files should remain yours alone. That's why we prioritize local-first AI, running open-source models directly on your computer.

User-owned

Your data, your rules. Jan stores everything on your device in universal formats, giving you total freedom to move your data without tricks or traps.

Fully Customizable

You can endlessly customize the experience with 3rd party extensions. You can adjust alignment, moderation, and censorship levels to your needs.
