Koro Interactive builds AI characters — real-time voice, long-horizon memory, animated presence — and operates them across product and social. Designed, engineered, and run in-house, end to end.
Capabilities
Persona-consistent conversation with layered memory — facts, moods, and relationships that persist across months, not sessions.
Neural TTS running on-device at ~150 ms per reply. No round-trip, works offline, lip-sync included.
Live2D rigging, expression systems, and reactive animation driven by conversation state.
Automated, in-character social presence across X, Instagram, and Threads — one character system, every surface.
Partners
We take a small number of partner engagements: original characters and avatar experiences for brands, built and operated on the same stack as NariYume.
Character design through deployment — app, voice, animation, memory, and social presence. Scoped per engagement.
