Tens of millions of people now hold regular conversations with AI characters. The use case is not productivity. It is presence: a consistent, available, non-judgmental entity that listens, remembers, and responds. That shift in user expectation has produced an industry.
The category has fractured faster than most observers expected. What started as novelty chatbots has split into distinct verticals: mental health companions operating under clinical oversight, creative roleplay platforms running on proprietary model stacks, senior care systems deployed through healthcare networks, children's companions designed with developmental criteria, habit-formation apps built around behavioral psychology, and pure social platforms treating character creation as a product in itself. Each vertical has different success metrics, different regulatory exposure, and a very different definition of what the relationship is for.
