AI avatar
Definition
A synthetic on-screen presenter that lip-syncs your script — used by tools like Synthesia and HeyGen for talking-head video.
An AI avatar is a digital presenter that delivers your script on camera with lip-sync, so you get a talking-head video without filming a person. It suits corporate training, onboarding and explainers.
Avatars are the opposite approach to faceless, visually-driven video, which uses b-roll and imagery instead of a presenter. SceneSynth focuses on the faceless style — see how it compares to Synthesia and HeyGen.
