Nowadays, many parents are facing practical difficulties in tutoring their children: busy with work, they can hardly spare enough time to accompany their children in study; lacking sufficient professional knowledge, they cannot accurately answer academic questions. Meanwhile, limited by class size, school classrooms struggle to meet the personalized needs of each student, resulting in children’s learning problems often not being resolved in a timely manner. With the in-depth integration of AI technology and education, the AI teaching assistant device specially designed for students’ learning has emerged as the times require. It breaks the limitations of traditional tutoring with its core advantages of intelligent adaptation, low-latency response, and interactive fun. It can not only provide children with all-day professional tutoring but also reduce the burden on parents, becoming an excellent bridge connecting school education and family tutoring.
