Common Questions
What is Spaced Repetition?
Spaced repetition is a learning technique that involves reviewing information at increasing intervals. Each time you recall a piece of information, the interval before the next review gets longer.
What is the FSRS algorithm?
FSRS (Free Spaced Repetition Scheduler) is a modern, neural-network-inspired algorithm that predicts exactly when you are about to forget something. It is significantly more accurate than older systems.
How much time will I save?
Research shows spaced repetition can cut your study time by 50% while improving long-term retention by over 90%.
What happens if I miss a day?
Don't worry! The algorithm is adaptive. It will re-adjust your schedule to ensure you get back on track efficiently without being overwhelmed by a "backlog".
Is this better than normal study?
Passive re-reading is the least effective way to study. Spaced repetition combined with active recall is considered the "gold standard" of learning science.
How does the AI generate flashcards and quizzes?
Our advanced AI analyzes your study materials (PDFs, notes, or lectures), identifies key concepts, definitions, and high-yield facts, and transforms them into interactive study cards and practice questions optimized for your exams.
Can I use this for non-academic subjects?
Absolutely. Spaced repetition works for languages, coding, hobbies, and even professional certifications.
Do I have to think about the schedule?
No, Masterly handles everything. You just open the app and click "Study"—the algorithm tells you exactly what needs review.
Which devices can I use Masterly on?
Masterly is available on Web, iOS, and Android. Your study sets and progress sync instantly across all your devices so you can study anywhere, anytime.
Is it hard to set up?
Zero setup required. Just create your cards or let our AI do it, and the system automatically starts managing your schedule.
