About

Nodebook

Features

Type any topic. Nodebook turns it into a clear lesson built from real, cited sources - then makes sure you still know it next month. Most learning apps stop at the explanation. Nodebook starts there. Every lesson comes with its sources, a quiz that tests understanding rather than wording, and cards that come back on a schedule tuned to your memory. Read it once, prove you know it, and Nodebook brings it back right before you would forget. WHAT YOU GET - A lesson on anything, in about a minute: the idea in plain words, the mechanism, a worked example, and the trap people fall into - Real sources you can open: every lesson cites where it came from, and a second pass checks its claims against those sources - Diagrams that are drawn, not generated: charts, formulas and structures rendered from the content, so they are correct by construction - A quiz that asks you to reason: predict, diagnose, spot the mistake - not "which of the following" - Cards you can write out or flip, graded by you, scheduled by spaced repetition - One daily session, served in stacks of ten, that knows what is due and why - Today's Nodle: a daily word puzzle drawn from your own lessons, with the lesson one tap away - Audiobooks with read-along and Audio Recall, which pauses to ask what you remember - Your library, sorted onto shelves automatically, with a map of how your ideas connect NODEBOOK PRO - 20 lessons a month, at full Professional depth - Scholarly sources - real papers with DOIs - Chaptered audiobooks Free accounts get 3 lessons a month with everything the practice loop offers. Nodebook is for curious people who are tired of reading something interesting and losing it a week later. Learn it once. Keep it. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the period. Manage or cancel in your Apple ID settings.
