Artificial human companion

An artificial human companion is a device or application designed to simulate companionship through social, emotional, or relational interaction. Examples of these systems include conversational agents, chatbots, digital pets, virtual avatars, or physically embodied robots.

Unlike task-oriented digital assistants, artificial human companions' capabilities include not just practical support but also often provide emotional presence, maintain ongoing social engagement, and/or cultivate interactions that resemble interpersonal relationships. They can engage in natural and dynamic conversations, provide assistance, offer companionship, and even perform tasks like scheduling or information retrieval. Their capabilities have expanded significantly with advances in artificial intelligence, large language models (LLMs), affective computing, and social robotics.
