Classmint is a new services that is currently free that allows users to create annotable, audible, and interactive notes. Notes can be kept private or they can be made public and shared. An automated revision list makes it easy to aid in timely revisions of the notes. Users can add complex math, computer code, images, explain notes with text, and then annotate images as well. The notes will then be read aloud if so desired. Users can annotate images and then mouse clicks will enable users to see the annotations. To learn more about Classmint, see the video below.
