"No matter how many times I review, I can't remember." "The knowledge I crammed before the exam vanishes immediately." AI technology combined with cognitive science offers a groundbreaking solution to these common learner frustrations. Memly's flashcard learning system has achieved a 74% improvement in memory retention compared to traditional methods.
In this article, we explain in detail why AI flashcards are so effective, along with the scientific evidence and practical methods behind them.
Why Traditional Memorization Is Inefficient
First, we need to understand why conventional study methods are not effective. According to the "forgetting curve" discovered by German psychologist Hermann Ebbinghaus in 1885, humans forget learned information at a surprisingly rapid rate.
| Time Elapsed | Retention Rate | Forgetting Rate |
|---|---|---|
| After 20 minutes | 58% | 42% |
| After 1 hour | 44% | 56% |
| After 1 day | 33% | 67% |
| After 1 week | 25% | 75% |
| After 1 month | 21% | 79% |
In other words, about 80% of information learned is forgotten within one month. Passive learning methods like "making summary notes" or "re-reading textbooks" are no match for this forgetting curve.
Spaced Repetition -- A Scientific Approach to Overcoming the Forgetting Curve
The most effective method for combating the forgetting curve, established in cognitive science, is spaced repetition.
Spaced repetition is a learning method that gradually extends the intervals between reviews. By reviewing at the "optimal moment" just as memory begins to fade, retention improves dramatically.
Spaced repetition is one of the most reproducible evidence-based learning techniques in cognitive psychology, grounded in approximately 200 years of research on long-term memory formation.
Why Reviewing at the Moment of Forgetting Is So Effective
Neuroscience research has shown that two key factors are critical for memory consolidation: the "testing effect" and "desirable difficulty."
- Testing Effect: The act of trying to recall information itself strengthens memory. Actively retrieving information is more than 3 times more effective than simply reviewing it.
- Desirable Difficulty: Reviewing when some effort is required strengthens the neural pathways of memory. Reviews that are too easy are a waste of time.
- Memory Reconsolidation: Each time a memory is recalled, it is reconstructed and converted into more stable long-term memory.
How AI Optimizes Review Timing
While the effectiveness of spaced repetition is scientifically proven, a major challenge has been determining "when and what to review." This is where AI technology brings revolutionary change.
Traditional Methods vs. AI Optimization
| Aspect | Traditional Methods | AI Optimization (Memly) |
|---|---|---|
| Review Timing | Fixed intervals (1 day, 3 days, 7 days) | Dynamic calculation based on individual memory patterns |
| Difficulty Adjustment | Self-reported | Automatically determined by AI from response patterns |
| Study Order | Random or sequential | Prioritized based on forgetting probability |
| Personalization | None | Optimized from individual learning history |
| Prediction Accuracy | Low | Industry-leading accuracy with FSRS 6.0 |
The FSRS 6.0 Algorithm Used by Memly
Memly uses the latest spaced repetition algorithm, FSRS 6.0 (Free Spaced Repetition Scheduler). FSRS 6.0 is a predictive model that combines machine learning with cognitive science insights, trained on over 1.7 billion review records.
Thanks to this algorithm, it is now possible to retain approximately 20-30% more information in the same study time compared to the traditional SM-2 algorithm (used by Anki and similar apps).
AI Flashcards in Practice -- Memly's Learning Flow
Step 1: Automatic Card Generation from Your Content
Memly's standout feature is its ability to automatically generate high-quality flashcards from your learning materials using AI.
- PDF/Text: Simply upload your textbooks or notes, and key points are extracted to create Q&A-format cards
- Images: Charts, diagrams, and handwritten notes are recognized and converted into appropriate questions
- Video: Lecture video content is analyzed and key points are turned into questions
The time previously spent creating cards is drastically reduced, allowing you to focus on the learning itself.
Step 2: AI-Optimized Review Schedule
FSRS 6.0 calculates the forgetting probability for each card in real time and presents reviews at the optimal timing. Cards you learn easily have their intervals extended, while difficult cards are reviewed more intensively.
Step 3: Visualize Your Progress with a Dashboard
A dashboard that shows your learning progress, retention rates, and upcoming reviews at a glance helps you maintain motivation while studying efficiently.
Proven Results -- What User Data Shows
The following results have been confirmed from data collected from over 3,000 Memly users:
| Metric | Result |
|---|---|
| Memory Retention Improvement | +74% (compared to traditional study methods) |
| Study Time Reduction | -32% (time needed to acquire the same amount of knowledge) |
| Learning Continuity Rate | 89% (active rate after 30 days) |
| Average Daily Study Time | 15 minutes (short focused sessions are most effective) |
Use Case Guide by Scenario
Professional Exam Preparation (TOEIC, Bar Exam, Medical Licensing)
For certification exams that require efficiently memorizing large volumes of specialized terminology and regulations, AI flashcards are particularly impactful. Simply uploading textbooks or past exam PDFs enables focused study on the most frequently tested topics.
Language Learning
Vocabulary, grammar rules, and example sentences are turned into flashcards and reviewed at optimal intervals based on the forgetting curve. Compared to traditional vocabulary books, you can acquire approximately twice the vocabulary in the same study time.
Programming Education
Programming also involves many elements that require memorization, such as API references, design patterns, and commands. AI automatically generates questions from technical documentation, helping you retain knowledge that is ready for real-world use.
Getting Started -- 3 Steps to Begin Right Now
- Create an account (30 seconds, no credit card required)
- Upload your study materials (supports PDF, text, and images)
- Start learning with AI-generated cards (feel the difference with just 15 minutes a day)
Even on the free plan, you can generate cards with 120 credits. Give it a try and experience it for yourself.
Conclusion
AI flashcard learning is a scientific solution to Ebbinghaus's forgetting curve. By leveraging AI to maximize the effects of spaced repetition, it achieves levels of memory retention that were previously impossible with traditional study methods.
Memly supports your transformation from "thinking you've memorized it" to "actually knowing it." If you want to fundamentally change the quality of your learning, give it a try.
