A free, open-source, self-hosted AI chat app for families
Run your own private AI chat experience on your local network.
No cloud services. No subscriptions. No data leaving your home.
LanJAM gives your family a shared AI assistant that runs entirely on your own hardware. Every conversation, every file, every piece of data stays on your local network — nothing is ever sent to the cloud.
- Private by design — your data never leaves your network
- Family-friendly — role-based safety system with age-appropriate content filtering
- Multi-user — each family member gets their own account with isolated data
- Offline-capable — fully functional without internet after initial setup
- Open source — inspect, modify, and contribute to every line of code
