Virtual humans — AI characters for brands

Distributed studio — Paris · Nice · Aix-en-Provence · Sophia Antipolis

A brand ambassador that never sleeps, never fumbles a press conference, and adapts to every channel. A Nexia virtual human is a brand asset — not a generic avatar.

Definition

A virtual human at Nexia is the design of a photorealistic or stylised digital character, built to represent a brand in digital spaces. Not a generic avatar created in 10 minutes. It is a complete brand asset: appearance, personality, voice, communication style, usage guidelines. A character your audiences recognise and trust.

Nexia combines AI image and video generation, 3D animation and LLM integration to create virtual humans capable of real-time interaction. AI generates visuals and accelerates animation. Human art direction guarantees brand consistency. For Initium, Nexia created the first virtual human integrated into a conversational WebGL experience.

Approach

What Nexia does differently.

01

A character, not an avatar

Nexia defines the character’s complete identity first: biography, values, voice, visual style. A coherent virtual human — not an interchangeable 3D skin.

02

Generative AI + human animation

AI generates the visuals and accelerates iterations. The team supervises movement and expression — the result looks like a premium studio creation, not raw AI output.

03

Conversational with integrated LLM

The virtual human can be connected to an LLM for real-time interactions. The character responds while staying in character and aligned with brand values.
