Real-time character technology
Koro is a studio that turns your character art into a live, lip-synced face and voice for the AI product you already operate — on web, iOS, Android, and kiosks. Animated in real time, never generated video.
Anime, illustrated, or true-to-life — you bring the art, we rig it into a live character with voice and motion.
2D by design. It renders efficiently, stays expressive, and avoids the uncanny-valley artifacts common in photoreal 3D.
Rigged & talking
Sample models
Sample renders — live results may vary. Every character is a real-time animation rig driven by your AI, not generated video.
You bring the character and AI stack. Koro adds a real-time face and voice, and ships it into your product.
Your character art in any style, and the language model and knowledge base you already run. Koro doesn't replace your AI — it gives it a face and voice.
We build the real-time animation rig and the neural voice, tune them to your brand, and wire them to lip-sync and react as your AI replies.
One character, live on web, iOS, Android, and kiosk — a lightweight layer that drops into the product you already run.
Physics-driven motion, expression, and lip-sync, generated live from your character art — anime, illustrated, or true-to-life. One renderer on web and native. Never a pre-baked video.
Web · iOS · Android · any art style
A lightweight neural voice — ~150 ms to first audio, lip-synced to the rig and tuned per character. Quantized to ~67 MB, it runs fully on-device.
~150 ms · ~67 MB · on-device
Web embed, iOS & Android SDK, and REST API. Weeks, not quarters.
Run offline on-device, reach larger models in the cloud, or route hybrid.
A single persona definition, consistent on every surface.
The same engine, three ways teams put it to work.
Banking, fintech, and app teams: the in-app assistant your customers already tap, upgraded with a face, a voice, and real-time presence — inside your app shell and compliance boundary.
F&B, retail, and sports: a character that greets customers and runs its own channels — daily posts in character, storylines, and replies to fans.
White-label the engine and run living characters as a managed content channel for your roster of brands.
Case study
NariYume is our iOS character app, built end-to-end on Koro. It uses the same real-time animation, neural voice, and on-device runtime we deploy for client products.
