Character technology studio
Koro Interactive is a studio that builds the real-time animation rig behind a digital character — the live face and voice that make a digital twin or bot feel present. We design and tune it for your brand, then drop it onto the product you already run. Rigged and animated live, never a generated video.
By 2026, almost every company runs an AI assistant, twin, or bot. More and more of them are giving theirs a face and a voice.
Most digital assistants live in a text box — capable, and forgettable. Engagement plateaus and users churn, because a chat window never feels like anyone is there.
That's changing. Airlines, banks, and telcos now put a speaking, on-brand avatar in front of customers — a character that greets, explains, and reacts, not a blank input field.
Koro builds the rig behind that shift — a real-time face and voice for your assistant, twin, or bot, built for a single brand. A face and a voice lift engagement, retention, and conversion. Presence converts.
Anime, illustrated, or true-to-life — you bring the art, we rig it into a live character with voice and motion.
Rigged & talking
The cast
Sample renders — live results may vary. Every character is a real-time animation rig driven by your model, not generated video.
One character definition. It runs inside your product, on its own channels, or both.
A live character inside your app, site, or kiosk — or a face and voice for the digibot platform you already run. It speaks as it replies and reacts on screen, driven live by your model. A lightweight layer, not a rebuild: web embed, iOS and Android SDK, REST API.
The character runs its own channels — daily in-voice posts, continuous storylines, replies to fans — unattended. One system feeding every platform.
Agencies license the engine and operate living characters as a managed channel for their roster.
The engine runs wherever the economics and the requirements point.
Voice synthesis and language inference run on the customer's hardware. No per-conversation API cost, works offline, and conversation data stays on the device. Suited to high-volume assistants where unit economics decide.
Hosted frontier models tuned to your brand voice and knowledge base. Higher reasoning quality, centralized logging and control, regional data residency.
Route by task — routine turns on-device, complex intents to the cloud. Most deployments land here.
Production components, not a demo reel.
A lightweight neural voice — ~150 ms per reply, lip-synced, tuned per character. Quantized to ~67 MB, it runs fully on-device.
A real-time character engine, built in-house — physics-driven motion, expression, and lip-sync from your character art. The same renderer on web and native.
One persona definition, consistent on every surface — in-product, social, kiosk, support.
SDK and API designed to sit inside an existing product. Integration is measured in weeks, not quarters.
On-device mode keeps speech and character state on the customer's hardware. Cloud mode gives you region and retention control.
Where the engine goes first.
The in-app assistant your customers already tap, upgraded with a face, a voice, and real-time presence — inside your existing app shell and compliance boundary.
F&B, retail, sports. The mascot posts daily, runs storylines, and answers fans — on autopilot.
White-label the engine and operate living characters as a managed channel for your roster.
We build and ship our own product on the same engine — NariYume, an AI character app on iOS.
Tell us the interface and the character you have in mind — we scope the build and return an estimate. Each character is a commission, built for one brand. Or email contact@korointeractive.com.
