The Science Behind Knowji

When you first learn a word, you start to forget it almost immediately.  If you don’t revisit the word and refresh your understanding of it, you will eventually forget it all together.  The key to memorizing a word is to revisit it enough times to transfer it into your long-term memory.  There is a problem though.  Endlessly learning the same words over and over may seem like the best way to commit words to memory, but it isn’t.  A better approach is to follow a rigorous, scientific methodology to learning, one that takes advantage of how your brain actually learns.  But unfortunately, most people waste time and effort memorizing words in a time consuming, exhausting, and often ineffective way.

What’s needed is a system that understands exactly what you know, and what you don’t know, so that when you are about to forget a word, the system can prompt you to learn that word at that moment.  That way, you only ever spend time learning words you need to learn, which in turn results in an incredibly efficient and effective learning process.

Knowji is exactly this system.  But to build it, we needed to understand how the brain learns.  A great deal of scientific research has been carried out in the area of psychology and memorization, and scientists now have a solid understanding of how memory works.  We leveraged this understanding by basing Knowji’s learning algorithm on these scientifically proven methodologies:

To maximize your learning potential, we’ve combined these existing methodologies with a series of unique learning features that we’ve designed, while hiding all of the complexity behind a deceptively simple interface.  Our apps won’t make you jump through hoops to enjoy a fast and effective learning experience.  When you start using any one of them, you’ll be learning right away.

Learning Modes

We use four different learning modes to thoroughly test your knowledge of a word.  We test both receptive and productive knowledge, and use your degree of knowledge (how well you know a word) to determine which mode to use for each word.  We begin with mode 1, and as you continue to demonstrate an increasing degree of knowledge, we gradually work up to mode 4.  The different modes are also useful in keeping you engaged in the learning process, with many of our users commenting on the game-like experience they enjoy when using Knowji.

Mode 1: Multiple Choice (Four Words)

Learning Mode One

Mode 2: Multiple Choice (Three Definitions)

Learning Mode Two

Mode 3: Word Recall With Spelling Practice

Learning Mode Three

Mode 4: Word Definition Active Recall

Learning Mode Four

Other Features

Knowji apps come packed with these great features:

Proper Pronunciation (Accent Reduction)

For any given word, record your own pronunciation and compare it with Knowji’s pronunciation.  Over time, reduce your accent as your pronunciation improves.


Try our fun quiz to test how well you know the words in any lesson. Choose from one of four different quiz modes to get just the right kind of challenge. All your quiz scores are stored so you can go back anytime and see how well you’re progressing.

Goal Setting

For every lesson you are learning, specify how many new words you want to learn each day, or set a date by which you want to have learned all the words in the lesson.  Knowji tracks your progress against your goal so you can always see exactly how you’re doing.


All words in Knowji apps are organized into lessons.  When you favorite a word, it is also added to your Favorites lesson.  This allows you to select just the words you want to focus on right now, and learn them quickly.

Drill Notifications

Knowji will send you a notification whenever it’s time to drill a lesson. So that no matter what you are doing, you’ll never miss the opportunity to keep on top of your learning.

Do Not Learn

If you already know a word, press the Do Not Learn button and it won’t show up when you are learning the lesson.  It’s a simple concept, but you’ll be surprised how many other apps waste your time forcing you to keep learning what you already know.

Progress Tracker

The progress tracker shows you how well you know every word in a lesson, and how you are tracking against your lesson goal setting.

Status Reports

Every lesson keeps track of your progress in a status report.  Ideal for parents who want to keep track of their children’s learning progress.


Knowji apps come with hundreds of words.  Search enables you to locate any word instantly.  Look up words by the word itself, definition, or example sentence.
