🎓 Mission: Great tutors are expensive, but knowing how to explain shouldn't be a luxury.
This tool uses Nobel laureate Richard Feynman's learning technique to give anyone — on any topic — a patient
tutor that teaches in plain words and analogies, and then helps you catch what you don't actually understand yet.

1What do you want to learn?
Type a concept, term, or question. The more specific, the better the teaching.
2Explain it simply
Feynman step 1: explain it so plainly that even a beginner gets it.
3Now you explain it
Feynman step 2: teaching is the best way to learn. Say it in your own words and the AI will show you what you haven't really grasped yet.
4Your understanding & gaps
Feynman steps 3 & 4: find the holes, then patch them with an even simpler explanation.
