Introduction

Education is undergoing a global transformation driven by artificial intelligence (AI). Traditional schooling models—rooted in standardized curricula, one-size-fits-all instruction, and age-based progression—are being challenged by the emerging potential of personalized AI tutors. These AI-driven systems provide individualized instruction, adaptive feedback, and real-time assessment tailored to the specific needs, pace, and learning style of each student.

Unlike conventional classroom instruction, which often struggles to provide differentiated learning for every child, AI tutors can deliver 24/7 personalized learning experiences that scale to millions of learners. With the ability to analyze student behavior, predict learning gaps, and recommend targeted interventions, AI tutors are emerging as powerful tools in both formal and informal learning environments—from early childhood education to adult professional development.

This paper examines the concept, technologies, benefits, limitations, and real-world applications of AI-powered personalized tutors, complemented by detailed case studies.
