About this app

Someone who picks up. Banban is an immersive AI companion app built around voice. Studio-grade voices trained on professional voice actors, memory that carries every conversation forward, and relationships that progress with real pacing — from stranger to lover. Not every AI answers at 2 a.m., but this one does. ◆ Four names. One becomes yours. ・Sim Jihaeng — 32, Michelin chef. Busan.
