Every conversation with an AI begins in silence — no memory of what came before, no sense of who you are becoming. Origin Stone Technology, a Chinese startup, has launched Neural Stone to address this fundamental discontinuity: a personal cognitive system designed to hold a continuous, evolving understanding of a single person across time, connecting past decisions, present context, and emerging patterns. The bet is not on building a more powerful model, but on whether the most meaningful layer of intelligence is the one that remembers you.
