HapYak allows users to easily add chapters, links, and quizzes to videos hosted on any OVP (youtube, vimeo, brightcove, wistia, etc). The best part is the ability to use templates to scale. Create one call to action (buy now, subscribe, download, etc) and apply it to hundreds or thousands of videos. Lots of integration options to google analytics and MAP systems, and also LTI integration so quizzes in videos can be used in learning assessments and LMS environments.
