Have made preparations for the duo. Turn Every Mistake into Personalized Practice with AI Mistake Notebook is an AI-powered learning app for students and parents. Simply take a photo of any difficult question, and AI instantly recognizes it, generates the answer and explanation, identifies the key knowledge points, and saves it to your mistake notebook or favorites. But AI does more than recognize questions. Based on each student’s mistakes, weak areas, knowledge points, difficulty levels, and preferred question types, AI automatically creates personalized practice questions with complete answers and explanations. Students can focus on the topics they struggle with, while parents can generate targeted worksheets in seconds—without searching, copying, or manually organizing questions. From AI-powered question recognition to intelligent practice generation, every mistake becomes a smarter way to improve.
