Flashcards built from your own material
One tap turns a set of notes into a study deck. Notlu picks the concepts worth memorising and schedules them with spaced repetition, so you review each card right before you would forget it.
Summaries you can revise from
Upload a PDF, record a lecture or paste a YouTube link. Notlu pulls out the key points, groups them by topic and gives you a structured summary — not a wall of transcript.
Introduction to Quantum Mechanics
Wave-particle duality is a fundamental concept where particles exhibit both wave and particle properties
The Heisenberg Uncertainty Principle states that position and momentum cannot both be precisely determined
Schrödinger's equation describes how the quantum state of a system changes over time
Quantum entanglement allows particles to be correlated regardless of distance
Turn dense notes into a mind map
Notlu reads your notes and draws the structure behind them — how each concept branches, connects and depends on the others. It is the fastest way to see a whole topic at once instead of re-reading ten pages.
