Digital humans integrating anthropomorphism into the performance and problem-solving features of AI offer innovative sources of insights and value that promotes a product, service, or brand. The purpose of this study is to investigate the effects of a digital human’s aura and anthropomorphism on perceived interactivity, attitude toward a brand, attitude toward a digital human, electronic word of mouth (eWOM) intention, and purchase intention. An entrenched digital human’s aura and anthropomorphism increase perceived interactivity, attitude toward a brand, attitude toward a digital human, eWOM intention, and purchase intention. This study contributes to the literature by clarifying the concept of the digital human’s aura and anthropomorphism and the relationships between perceived interactivity, attitude toward a brand, attitude toward a digital human, eWOM intention, and purchase intention.
