Give your digital assistant a face and a voice.

Koro's character engine turns a scripted in-app assistant into a live character — real-time speech, an animated face, and memory of the customer. It drops into the interface you already run.
One character definition. It runs inside your product, on its own channels, or both.
A live character inside your app, site, or kiosk. It speaks as it replies, reacts on screen, and carries context across sessions. 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.
Neural TTS at ~150 ms per reply, lip-synced to the character.
Live2D, or a rig built from your existing character art. Expression and reaction driven by conversation state.
Customer context that persists across sessions and months — the character remembers the relationship, not the last message.
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.
A recorded integration walkthrough.
Where the engine goes first.
The in-app assistant your customers already tap, upgraded with speech, a face, and continuity — 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.
Every engagement is scoped: character design or your existing IP, integration, and operation. Fixed scope, fixed deliverables.
