NODELAND FEYNMAN

If you can explain it,
you start to understand.

Choose an idea. Explain it in your own words. A curious student helps you notice what could still become clearer.

Three apps. The same NodeLand account.

From an idea to the next question.

01

Choose what to explain.

Start with the daily challenge, browse the catalog, or type a concept you are studying.

02

Explain it your way.

Pick an audience and write in your own words. Then the student asks questions to help make the idea clearer.

03

Revise and see your result.

Rewrite if you want, finish the practice, and review the feedback. You can also publish to the ranking when you are ready.

These practices guide our product choices. Learning research is our starting point, not a promise of individual results.

Before you start

What is Feynman?

It is a space to practice explaining concepts in your own words, receive questions and feedback, and optionally join a ranking.

Can I use my NodeLand account?

Yes. Canvas, Flashcards, and Feynman share the same account. Each app’s content remains separate.

Does the score measure what I know?

No. The score and ranking are a playful incentive, not a validated measure of mastery or a promise of learning outcomes.

Where can I use it?

The web app is available at feynman.nodeland.io. The Open Feynman button takes you directly there.
