From document to deck in one click
No manual card writing
Making flashcards by hand takes hours you don't have. Upload a PDF and NexSpace's AI reads it, identifies the testable concepts, and generates a complete flashcard deck: definitions, key equations, comparisons, whatever the material calls for.
SM-2 spaced repetition, not random review
Cards aren't just generated. They're scheduled. NexSpace uses the SM-2 algorithm to show you each card right before you're about to forget it, so review time goes toward what's actually slipping, not what you already know.
Every card traces back to its source
Each flashcard stays linked to the page or section it came from. If a card doesn't make sense, jump straight back to the original material for context.
Built for streaks, not cramming
A daily due count and streak tracker keep review sessions short and consistent: the opposite of a last-minute cram session the night before an exam.
