This is another of the very few tools on here which need to be purchased.  It is worth including though as the power of this tool for student voice is fantastic.

Every1Speaks allows you to create an idea (students can too if you wish to enable this).  Students then have access to comment on that idea as they see fit.  The software visually shows different opinions and viewpoints using graphics to portray the amount of discussion around an idea (i.e. a crowd of students in a hard grows larger the more an idea is discussed).  This means that by simply looking at the idea map you can see which ideas are closest to the hearts of the students and then dive in for their views.  Once an idea reaches a certain size (has a certain amount of discussion around it) a specified member of staff is also informed by email to let them know they should be taking notice of this one.

The page below is from the Every1Speaks website and explains the tool in more detail:
