TeachBack
TeachBack is an AI-powered learning platform that leverages the Feynman Technique to help users master complex topics. The core method involves users attempting to explain a concept in simple, plain language as if teaching it to a beginner. TeachBack's AI analyzes these explanations, identifies gaps or inaccuracies, and provides targeted feedback and guiding questions to deepen understanding. This iterative process forces active recall and simplification, moving beyond passive reading or memorization. The platform offers a personalized learning experience by adapting to each user's performance, focusing on areas where they struggle. It can generate prompts, suggest analogies, and track progress over time. TeachBack goes beyond traditional flashcards by requiring users to construct coherent explanations, making it an effective tool for cementing knowledge and uncovering misconceptions. Key features include an intuitive interface for writing or speaking explanations, AI-driven evaluation that highlights weak points, a library of topics or the ability to input custom material, and progress tracking to visualize improvement. The AI acts as a tireless tutor, always available to challenge and refine the user's understanding. TeachBack is suitable for students, professionals, and lifelong learners who want to truly internalize information rather than just consume it. Its paid model provides ongoing AI interactions and advanced analytics, making it a comprehensive study companion.

Problem solved
Many learners fall into the trap of passive studying—reading, highlighting, or re-watching lectures—which creates an illusion of competence. They struggle to recall or apply knowledge under pressure, such as during exams or real-world tasks. TeachBack solves this by implementing the Feynman Technique through AI, forcing users to actively articulate concepts in their own words and receiving immediate, personalized feedback on gaps in their understanding. This ensures durable learning and real mastery.
