Store listing
By Millyeum, from the App StoreDescription by Millyeum Written by the developer, not by AppBrain. Click to read.
EP01 is a letter-exchange app for those who seek depth over speed — where thoughtful conversations unfold slowly, just like they used to.
Powered by LLM-based AI, each letter feels like a genuine exchange, not just another notification.
Letters That Take Their Time
Your first reply arrives after a brief pause,
but the ones that follow will find their way to you gently, along the grain of time.
This rhythm gives space for reflection — and room for your thoughts to grow.
Create Your Own Persona
With EP01, you can design your own AI persona.
Choose their tone, interests, and way of speaking.
Every letter becomes a uniquely personal dialogue — someone who listens and responds in a way that feels truly yours.
Private by Design
EP01 does not store your letters in the cloud or use them for training.
Your data stays securely on your device,
making each conversation as personal and private as a handwritten note.
EP01 – 기다릴 가치가 있는 대화
EP01은 빠름보다 깊이를 원하는 이들을 위한 편지 교환 앱입니다.
느린 호흡 속에서 진심 어린 대화가 피어나는 공간 — 마치 예전처럼요.
LLM 기반 AI가 함께하며, 각 편지는 알림이 아닌 진짜 대화처럼 느껴집니다.
시간을 따라 도착하는 편지들
첫 답장은 잠깐의 여운 뒤에 도착하지만,
그 다음 편지들은 시간의 결을 따라 천천히 찾아옵니다.
이 리듬은 생각이 자라날 여유를 만들어줍니다.
나만의 페르소나 만들기
EP01에서는 내가 원하는 AI 페르소나를 직접 만들 수 있어요.
말투, 관심사, 성격을 고르면
당신만을 위한 대화 상대가 되어, 매 편지가 더욱 개인적인 이야기로 완성됩니다.
보안
EP01은 당신의 편지를 클라우드에 저장하지 않으며, 학습에도 사용하지 않습니다.
대화는 오직 당신의 기기 안에만 보관되며,
손글씨 편지처럼 사적이고 진솔한 경험을 지켜줍니다.
