Blikbook is designed to increase collaboration between students and professors outside of the classroom.  Q&A "rooms" can be created for a specific course.  These rooms are meant to be a forum where students can ask questions with answers supplied by classmates and professors.  Top answers can be highlighted to create an evolving FAQ section for a course as it progresses.

The product is currently free - the company believes that charging professors for data on how engaged students are (as a virtual class participation grade). 

Existing customers include University College London, Westminster University and The University of Aberdeen.
