Introduction

Ever crammed for an exam, only to forget everything the next day? Well you’re not alone—it happens to the best of us. The problem isn’t that you’re not trying hard enough; it’s that traditional study methods don’t really match how our brains work. The SuperMemo algorithm is useful in this situation. By employing spaced repetition, it is intended to help you retain information over time by reminding you of the things you are most likely to forget at the precise moment you need to recall them.

The problem is that while SuperMemo is excellent at indicating when to review, it doesn't genuinely improve your comprehension of the content. Coastflow alters the rules in this situation. By automatically creating excellent flashcards and explanations from your notes, Coastflow is more than just another flashcard app; it helps you learn more effectively. No more making cards by hand or fumbling with problems on your own.

What is the SuperMemo Algorithm - Why does it matter?

If you’ve ever used a flashcard app, chances are you’ve already benefited from the SuperMemo algorithm—even if you didn’t realize it. Developed in the 1980s by Dr. Piotr Woźniak, SuperMemo was one of the first systems to utilize spaced repetition to learn.

What is the significance of spaced repetition, then? SuperMemo organizes your reviews according to how well you recall each item of information, as opposed to cramming all at once or reviewing everything at random. You'll see a flashcard again sooner if you have trouble with it. The system will wait longer before displaying it again if you get it properly. This approach is based on the forgetting curve, which essentially demonstrates that unless we actively reinforce something, the human brain gradually forgets it. 

🔹 Consider it your brain's clever coach, encouraging you to practice your weak areas while allowing you to rely on your strengths. 

Most flashcard apps now come with this algorithm as a basic feature, which helps pupils remember information more easily and with less effort. The problem is that, although SuperMemo aids in scheduling reviews, it has no effect on the caliber of the knowledge you acquire. This is where Coastflow's AI-powered strategy really shines.

Instead of just reminding you when to review, you can learn smarter through the use of high-quality flashcards and instant explanations when you need them.

1. The Forgetting Curve: Why We Lose Information Over Time

We must begin with the forgetting curve, a theory put forth by psychologist Hermann Ebbinghaus in the late 19th century, in order to comprehend why SuperMemo works so well.

According to the forgetting curve, unless we review and reinforce information, we lose it quickly.

• Right after learning something, you might remember 90% of it.

• A day later, without review, you may remember only 50%.

• A week later, that number can drop to 10% or less!

Ebbinghaus found that exposing people repeatedly at predetermined intervals improves memory retention and delays forgetting. This is the principle that SuperMemo is built on.

2. The Spaced Repetition Process in SuperMemo

SuperMemo is more efficient than conventional rote memorization because it operates in cycles of increasing intervals.

This is a basic explanation of how it operates:

Step-by-Step Process:

1. Initial Review: You gain new knowledge (for example, "What is the capital of France?" → "Paris").

2. First Testing: To help you remember it, you see the flashcard again in a few minutes or hours.

3. Spaced Intervals Begin:

• If you recall it easily → the next review is pushed further out (e.g., 1 day, then 4 days, then 10 days).

• If you struggle → the algorithm reschedules it sooner (e.g., later the same day or tomorrow)

4. Optimized Long-Term Retention: Over time, facts you remember well appear less often, while difficult ones get more frequent attention.

🔹 Think of it like strength training—revisiting the weaker concepts more frequently helps build "mental muscles" until the information sticks permanently.

3. SuperMemo Versions: How the Algorithm Has Evolved

The original SuperMemo SM-2 (1987) is still frequently found in flashcard applications today. It introduced the interval-based approach, in which user feedback (easy, medium, and hard) was used to schedule reviews.

SuperMemo SM-15+ (2008 and later): Adaptive learning was introduced, allowing the algorithm to change more dynamically according to user performance and degree of difficulty.

Current AI-powered variants: In order to better optimize review scheduling based on cognitive science and user behavior, several more recent learning platforms incorporate AI-driven spaced repetition.

4. Why SuperMemo Works Better Than Traditional Studying

Most people study inefficiently because they:

• Cram all at once, leading to short-term memory retention.

• Review everything equally, even things they already know well.

• Don’t space out reviews, causing rapid forgetting.

SuperMemo solves these issues by:

• Ensuring that you review only what you need, when you need it.

• Reducing unnecessary repetition and wasting less time.

• Making long-term memory formation nearly automatic.

With SuperMemo, you learn smarter, not harder—staying efficient and retaining information with minimal effort.

SuperMemo is still one of the best methods for retaining information, but AI-powered learning platforms (such as Coastflow) are going one step further by enhancing not only review schedules but also:

1. Producing excellent flashcards automatically from notes, saving you the trouble of creating them by hand.

2. Delivering explanations in real time so that you fully comprehend topics rather than just memorize them.

3. Modifying the learning process (e.g., changing the number of reviews, focus regions, and card length).

This combination of spaced repetition + AI assistance makes learning faster, more engaging, and way more effective than traditional study methods. So why not give it a try today?
