How It Works

Vocabulary Genius predicts how well you know every word in the English language.

Choose a list, and Vocabulary Genius will teach you the "best" words first, which are the most common words that it thinks you don’t know yet.

Vocabulary Genius repeats words at just the right time, before you’re likely to forget them, in order to maximize retention.

Vocabulary Genius uses innovative algorithms based on the spaced repetition learning theory. It understands that you forget with time.

Tip: As you complete lessons in Class Ace, Vocabulary Genius updates its ‘knowledge model’ of what you know. It tracks your positive and negative interactions with each word. This all helps you learn more in less time.
