Robin Good: GroupMap is a visual mapping tool that allows groups of people to collaboratively work around specific ideas, problems or issues.
Instead of offering a generic mindmapping tool and letting users find their application for it, GroupMap has been designed with a specific application in mind, providing much greater value to those interested in improving decision-making processes, creative brainstorming and idea-generating sessions .
"GroupMap shows you what the group is thinking by combining the views and ideas of individual participants."
The free version allows up to five contributors per map.
