Definition & guide

What Is a Digital Human?

A plain-English definition — the types of digital human, how they're different from avatars and chatbots, and what they're used for.

A digital human is a computer-generated, lifelike human figure — a realistic face and voice — used to interact with or represent people. The interactive kind holds live, real-time conversations; the term also covers pre-rendered digital humans created for video, film and games.

Two types of digital human

Interactive (real-time)

Converses live — it listens, understands and responds in the moment with a talking face and voice. This is what businesses use for receptionists, kiosks and support.

Pre-rendered

Created in advance as a fixed asset — a presenter in a video, a character in a film or game. Lifelike, but it doesn't respond; it plays back.

For customer interaction, the interactive, real-time kind is what matters — a real-time AI avatar is exactly that.

Digital human vs avatar vs chatbot

  • Digital human: emphasizes lifelike, human realism — a believable face and voice.
  • Avatar: a broader term for any digital character representing a person or brand, realistic or stylized. A real-time AI avatar is an interactive digital human.
  • Chatbot: exchanges text or voice with no embodied face — the step before a digital human gives it a believable on-screen presence.

What digital humans are used for

Reception & front desk: a branded face that greets visitors and answers questions.

Kiosks & retail: always-on assistants in stores, lobbies and public spaces.

Support & sales: answering customers and guiding purchases online, in real time.

Media & training: pre-rendered presenters for videos, courses and entertainment.

Getting an interactive digital human

For customer-facing use, you'd deploy an interactive digital human through a real-time avatar platform. Selvia AI is one example — an all-inclusive, real-time talking digital human with per-user memory that runs on a website, phone or in-person kiosk, from $1/hour. It's a practical way to see what a digital human can do for a business.

What is an interactive digital human?

One that converses in real time — it listens, understands and responds live with a talking face and voice, rather than being pre-rendered. This is the kind businesses use for receptionists, kiosks and support, as opposed to digital humans created for pre-recorded video.

Is a chatbot a digital human?

Not quite. A chatbot exchanges text or voice without an embodied, lifelike face. A digital human adds a realistic on-screen face and voice, so the interaction feels like talking to a person rather than typing into a box.
