The first step to learning is writing it down.

KnowledgeStacks provides a simple easy to use note taking UI that was designed for use with tablets and modern cell phones.

The note UI allows you to take a note, attach a question to the note, and attach a hand drawn scribble to the note

After taking notes, you can only be sure that you have learned it by challenging yourself to recall it.

Every note can have a question attached to it. These are not multiple choice, you must be able to recall without deduction.

This can be done in either the note UI or the curate UI, your choice.

The notes and questions can then be used in a quiz mode where you can select how difficult it was to recall the information.

KnowledgeStacks remembers your difficulty history for each "Stack" of notes and questions so you can watch your progress.

An often overlooked aspect of learning is interacting with the information outside of formal study

Spending time enhancing and augmenting notes with images and audio can deepen the connections in your mind.

KnowledgeStacks has a curate mode that allows you to add images, audio and scribbles to notes.

In addition there is a presentation editor that allows you to make simple slides that can be used for presentations or quizzes .

In presentation mode you can create slide shows that automatically advance based on time or audio.

Curated quizzes incorporate visual and audio information to help aid in recall.

Individual notes can also be assigned context tags which are used to filter quizzes and presentations to target areas of difficulty.

Learning is social and the ability to share notes is critical.

KnowledgeStacks allows you to export "stacks" to share with those in your study group.

KnowledgeStacks also allows you to merge stacks. Work can be split up between members of a group and merged together later for study sessions.

Stacks can also be filtered and subsets of stacks can be split off into their own stack for additional focus and sharing.
