StudyBuddy is an engaging, interactive learning experience where users deepen and reinforce their knowledge by teaching an AI chatbot. The tool is designed for middle and high school learners who need help focusing their study time and identifying which topics to prioritize. By putting learners in the position of a teacher, StudyBuddy lets students teach what they have learned, and asks follow-up questions to probe the depth of their understanding. The AI is reliably trained to identify knowledge gaps and misconceptions, allowing students to quickly see where they need more review. StudyBuddy brings the benefits of 1-1 attention and the power of learning by teaching to all students.
