EP01 β Conversations Worth Waiting For EP01 is a letter-exchange app for those who seek depth over speed β 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 β 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 β 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.
