Why do we forget things? And more importantly, how can we stop it? The answer lies in the "Forgetting Curve" and a technique called Spaced Repetition.

In the late 19th century, psychologist Hermann Ebbinghaus discovered that human memory declines exponentially after learning something new. If you don't review the information, you'll lose about 70% of it within 24 hours.

Spaced repetition is the practice of reviewing information at increasing intervals (e.g., 1 day, 3 days, 1 week, 1 month). Each review "resets" the forgetting curve and makes the memory more durable.

Revewing too soon is a waste of time. Reviewing too late means you've forgotten it. The "sweet spot" is reviewing exactly when you're on the verge of forgetting.

Calculating review intervals used to require spreadsheets or shoeboxes of index cards. Akadie AI does it automatically.

Every time you interact with a concept, our algorithm calculates the optimal time for your next review. We show you exactly what you need to study, exactly when you need to see it.

By using spaced repetition, you can move information from your short-term memory to your long-term memory with minimal effort. It's not just studying; it's engineering your brain for success.
