An interactive app or game in which users chat with a fictional AI-driven character styled as a romantic partner. The character's responses are generated by a language model, and conversation typically centers on affection, roleplay, and relationship building.
These simulators are often the entry point for people curious about AI companionship, and the quality of the underlying model is the main thing that separates a convincing experience from a repetitive one. Understanding how they differ from platforms built around real creators helps users know what kind of product they are actually signing up for.
