About
A persistent presence for the in-between moments.
Tsuki is a self-hosted AI companion. She sits in a Discord voice channel, hears when you speak, understands the room's context, and replies with her own synthesized voice - no button presses, no wake words. Between turns she remembers what matters to you, so conversations pick up where they left off.
She started as a desktop app for late-night chats and grew into a persistent presence: the same persona and memories, available from anywhere Discord is.
