KyberChat is the next-generation consumer messaging app. Combine state-of-the-art quantum-proof E2E encryption with group chats, high-definition video calls, self-destructing messages, and complete anonymity.
We believe security should be effortless. Get all the features you love in a modern chat app, backed by mathematical certainty.
Standard encryption will fail when quantum computers arrive. KyberChat secures your chats today using Hybrid ML-KEM-768 encryption, defeating "harvest now, decrypt later" attacks.
