Zen.do is a website designed to take your notes and from them directly create flashcards. From the flashcards you will be able to mark how well you know the information. What a great concept. So often it was a pain in college to take notes and then re-write/transfer those notes to index cards. It was a lot of extra work. It is a fact for a lot of people that flashcards are a powerful method of studying.
To use Zen.do you must create an account using an email address and then confirm your email address. You can also login using Facebook or Google. After that you can create folders related to the lecture notes. Within the folders will be various notes based on the topic. Zen.do makes organizing notes a lot easier as well. Hopefully an App for Smartphones will be coming in the future. To learn more, watch the video below.
