Created by two high school students in San Jose, California (and one college freshman), Stoodle is a free collaborative online whiteboard allowing students to connect with their teacher, tutors, or peers to work on homework assignments or illustrate a drawing to show their thought process in real time. It’s as simple as creating an account and sharing the URL. Communication occurs on a virtual whiteboard with infinite pages through voice conferencing and text chat, upload images, and annotate using basic drawing tools and colors. It works on desktops, tablets and iOS devices.
