What Are AI Avatars and Digital Humans?
AI avatars are digital human representatives created or directed by artificial intelligence. This technology allows you to produce realistic human-looking videos from text or audio input. You can create video content without going in front of a camera, setting up a professional studio, or even showing your own face.
AI avatar use cases: - Corporate training videos - Product introduction and demo videos - Multilingual customer service - Social media content - News and informational videos - E-commerce product descriptions - Personal brand videos
