Real-time character technology

Give your digital assistant, twin, or bot a face and a voice.

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.

Any art style.

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

Style studies shown. Final output depends on source art and rig design. Every character is a real-time animation rig driven by your AI, not generated video.

How it works.

You bring the character and AI stack. Koro adds a real-time face and voice, then deploys it across your product surfaces.

1

Bring your character and AI

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.

2

Koro rigs the 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.

3

Ship it to your surfaces

One character across web, iOS, Android, and kiosks — integrated through Koro's SDKs and API.

Animation

Real-time character rig

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 embed, iOS and Android SDKs, and a REST API. Integration in weeks, not quarters.

On-device or cloud

Run offline on-device, reach larger models in the cloud, or route hybrid.

One character runtime

A single persona definition, consistent on every surface.

Where Koro fits.

The same engine, three ways teams put it to work.

In your product

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.

Brand mascots

F&B, retail, and sports: a character that greets customers and runs its own channels — daily posts in character, storylines, and replies to fans.

Agencies

White-label the engine and run living characters as a managed content channel for your roster of brands.

In production

Built on Koro: NariYume.

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.
