AI for all — whether you are online with 40+ frontier models, or offline on your Windows PC with full privacy. One mission. Two products.
Our mission — AI for all
LumiChats started with one belief: powerful AI should not be locked behind expensive subscriptions or require an internet connection. The web platform gives you 40+ frontier models in one tab. The offline app gives you the same power — completely private, completely free, running on your own device.
