Invisible protection
It feels like a normal assistant.
It isn’t built like one.
Privacy happens before the network—not after your information has already left your hands.
VanZen protects it
Personal details become typed placeholders before dispatch. The model reasons without receiving the originals.
You get the answer
Allowed details are restored only for you. The most sensitive types are structurally prevented from reappearing.
You set the boundary
Private when it’s personal.
Open when you’re exploring.
Each conversation has a clear mode. There’s no buried global switch and no ambiguity about how your message is handled.
