They lack calibrated uncertainty, ignore sequential evidence, and drift during long interactions. We present \\textbf{AI YOU}, a framework that continually updates a personality profile with 22 dimensions from conversation and embodies it in a personal digital twin. Practically, the system combines prompting, Bayesian updating, and conformal prediction for persona inference. A periodically refreshed memory anchor and cognitive memory with three layers preserve persona consistency over long interactions. Across the main results, AI YOU \\emph{(i)} achieves conformal coverage ranging from 0.921 to 0.976, \\emph{(ii)} improves uncertainty calibration and reasoning grounded in memory, and \\emph{(iii)} enhances persona fidelity over static prompting in role playing over 100 turns while reducing trait drift, for most evaluated backbones under adversarial settings with multiple agents. The prototype \\emph{AI YOU Town} initializes an imaginative twin world for future interaction.
