“And what, Socrates, is the food of the soul? Surely, I said, knowledge is the food of the soul.” - Plato
memoread can help you to memorize more knowledge, for free!
The scheduling algorithm behind memoread is based upon an early learning algorithm from SuperMemo.
Although there exist a number of applications that can aid with memorizing information, none of these applications (to my knowledge) are specifically targeted towards online information.
A large amount of primary research is now distributed via the internet, and considering the fact that the majority of the research in any given field has been conducted within the past century, it makes sense to stay on top of the data, memorizing new knowledge of importance.
Of course, you don't have to use memoread for research. You may find memoread helpful for recipes, news articles, biographies, and any other online information that you can think of.
