Kayuda is a web-based visual wiki, a mind-mapping tool, and a non-linear writing tool that allows you to track ideas and the relationships between them. It's free, and any number of people can collaborate simultaneously in real-time. You can have any number of "wikis" (called "workspaces"), and you can choose how private to make them.
