Understand any PDF or topic with the Feynman technique, powered by AI

The Feynman technique says you only understand something when you can explain it simply. This free tool applies that method to whatever you give it — a PDF, a document, or pasted text. The AI rewrites the material in plain language as if teaching a beginner, then checks your grasp with multiple-choice questions, flags the misconceptions people usually fall into, connects the idea to the real world, and ends with the key insights that prove you actually get it. Students use it to break through confusing chapters, teachers use it to find simpler explanations, and the curious use it to learn anything faster.
