Knowtes is a flashcard-based learning community;

"Knowtes optimizes your study. By adding a card to your Knowtes memory, it becomes due at optimized intervals. The Knowtes Adaptive Learning Engine then adjusts how frequently you have to study cards in your memory based on how well you do on them. No more wasting time on cards you already know by heart. You can even visually watch your cards move from short to long-term memory as you study them!"

• Highly customizable interface
• Dynamic study graphs
• Embed your decks on your own web page
• Integrated music player (desktop library only)
