Common questions about Feynman AI
Feynman AI covers all academic and professional disciplines — mathematics, physics, chemistry, biology, computer science, economics, humanities, and professional skills. Our curated concept library spans dozens of subjects, and you can also create custom topics from your own notes or textbooks. The AI adapts its analysis to domain-specific terminology and standards.
Getting started takes under 2 minutes: download the free app on iOS or Android, choose a subject or paste your own study material, review the structured concept brief, then explain the concept in your own words — by text or voice recording. The AI instantly scores your explanation on accuracy, clarity, structure, and use of examples, then provides targeted suggestions to deepen understanding.
Feynman AI uses advanced natural language processing to evaluate your explanations across four dimensions: factual accuracy, conceptual clarity, logical structure, and illustrative examples. Research on the Feynman Technique shows that learners who explain concepts in their own words retain up to 90% more than those who passively review. The AI pinpoints knowledge gaps and provides line-by-line guidance to help you refine each explanation.
Feynman AI serves students preparing for exams, self-learners acquiring new skills, knowledge workers who need to communicate complex ideas clearly, and educators refining their teaching. The app supports 9 languages and adapts to any level — from introductory courses to advanced professional topics.
Yes. According to learning science research, active recall through self-explanation is one of the most effective study strategies, significantly outperforming passive re-reading and highlighting. By explaining concepts in your own words and receiving targeted AI feedback, you build stronger neural pathways and achieve deeper long-term retention.
Absolutely. Feynman AI provides transparent privacy controls and handles all data responsibly. Your study content and explanations are used solely to generate personalized feedback. See our Privacy Policy and Terms of Service for complete details on data handling and your rights.
