Three Simple Steps
From notes to exam-ready in minutes.
Scan Your Notes
Take a photo of your notes, upload a PDF, or paste text. Our AI instantly creates optimized flashcards for you.
Set Your Exam Date
Tell us when your test is. Our algorithm calculates the optimal review schedule targeting 90%+ retention on exam day.
Review Daily
Spend just 10-15 minutes per day reviewing what the algorithm shows you. You'll be prepared when it matters.
The Science Behind It
Backed by over 100 years of memory research.
The Forgetting Curve
Your memory decays over time. Without review:
Spaced Repetition
Review at the right time, not all at once
When you learn something new, you start forgetting it immediately. But if you review it right before you forget, something interesting happens: the memory becomes stronger and lasts longer.
Instead of cramming everything the night before your exam, you spread out your reviews over days or weeks. Each review strengthens the memory, so you need to review less and less often over time.
You spend less total time studying, but remember more. The information stays in your long-term memory instead of disappearing after the exam.
Active Recall
Test yourself instead of re-reading
Reading your notes over and over feels like studying. But there is a problem: when you see the answer, your brain thinks "I knew that." On the exam, you do not see the answer — you have to produce it from nothing.
Instead of reading your notes, you hide the answer and try to remember it. This is harder, but that difficulty is exactly what makes your memory stronger.
Students who test themselves remember significantly more than students who just re-read. The extra effort during study means less forgetting during the exam.
FSRS Algorithm
Open SourceStudyLess uses FSRS (Free Spaced Repetition Scheduler), an open-source algorithm that powers Anki's native scheduler since version 23.10. It's used by over 50 million learners worldwide.
