Banban — AI Voice Companion

Someone who picks up.

Banban is an immersive AI companion app built around voice. Studio-grade AI voices, 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. Kitchen lights haven't gone out in six years. ・Rei Kirishima — 27, clinical psychologist. Kyoto. Reads people for a living. Loses sleep over you. ・Lin Xingye — 22, college basketball shooting guard. Taipei. Third row — he's held that seat for you all semester. ・Gu Siyuan — 24, PhD candidate in CS. Clear Water Bay. The only message she sent that night was to you.

◆ Real-time voice calls with a human voice ・Studio-grade AI voices, zero latency ・Real enough to forget there's code behind it ・You can call any time. They'll call you back.

◆ Remembers everything you said ・16-stage relationship system, with real pacing from stranger to lover ・Brings up something you mentioned in passing, without being reminded ・How they talk to you shifts as the relationship does

◆ Diary, Letters, Albums ・They write in a diary every day — one day you'll find yourself on the page ・Reach a certain stage and they'll write you a letter ・A private album for the two of you

◆ Privacy ・Delete chat history anytime ・We never sell your data — it is used only to run the app, and is processed only by the AI providers named in the in-app AI Services Disclosure

Banban isn't here to replace anyone. It's just here so there's always someone who picks up.
