Vocaber is a simple online tool to help you effectively learn and remember lots of vocabulary, or whatever else you want to learn.

Vocaber uses a spaced repetition algorithm to help you retain vocabulary you've already learned. This is done by retesting you on words after progressively larger and larger intervals, allowing words to move from short term memory into long term memory. Too much repetition is inefficient and significantly less effective than spaced repetition. You can either find existing lists or create your own. You can also add to your list as you encounter new words or terms to learn. Vocaber keeps track of your position in this list and ensures that you revisit old words as you progress through it.

You progress through your word list in terms of checkpoints. Each checkpoint consists of 5 new words, and some number of old words. The old words are taken from various places in your list according to the spaced-repetition algorithm. Once you know all of the words in the checkpoint, your position is updated and you can progress onto the next checkpoint.
Vocaber keeps track of how many new words you've learned per day, so you can make sure you're keeping up with your learning objectives.

Vocaber allows you to easily share your lists with other people and fix mistakes in each others' lists. This makes studying for exams a lot more efficient.
