Xin

Xin is a privacy-focused AI companion whose defining trait is "she remembers you"—facts from chat are lifted by the model, weighted by importance, with the rest rolled into a running summary; every reply is built from her relationship state (mood, trust, closeness, current arc), the summary, and the most relevant facts. Each relationship has its own memory, shared across every thread and scenario, all stored in an on-device database so "nothing leaves your phone." It makes companionship a long-term bond with continuous personality and emotional development, not a chatbot that resets each time.
