Free AI Avatar Generator

An AI avatar is a digital representation of a human in a virtual setting generated by artificial intelligence. They are virtual personas that can simulate human-like behaviors, emotions, and interactions and are often seen used in AI talking head videos, where the avatars speak and respond just like a real people.

Synthesia’s stock AI avatars are trained on real actors with their explicit consent, and actors are paid per video that’s generated with their image. The base video footage is then processed by an AI model which creates new videos from text.
