What is the spacing effect?

The Science of Remembering

Spaced repetition shows you cards right before you'd forget them. The more you know a card, the longer until you see it again. Simple, but incredibly effective.

FROM READING TO LEARNING

Highlights Become Cards

When you highlight text in an article, you can instantly create a flashcard. The highlight becomes the answer, you write the question. Done.

Highlight → Flashcard

Question:

What percentage of information is forgotten within one hour without review?

Answer (from highlight):

"Within one hour, people forget approximately 50% of new information"

Article: "The Forgetting Curve"

Hermann Ebbinghaus discovered that memory retention declines exponentially. Within one hour, people forget approximately 50% of new information without any review. This led to the development of spaced repetition systems.

SM2 Algorithm

Metis uses the SM2 algorithm, the same proven system behind Anki. It calculates optimal review intervals based on how well you know each card.
