I have been working a lot with the Google App Mindomo recently at my schools and I'm really impressed with this app! Mindomo is a mind mapping tool that helps keep track of ideas by putting them together visually. Mind maps can then be easily made into a "Prezi-like" presentation or the text can be downloaded into a doc in Google Docs to be edited by students. Mindomo offers features like design themes and layouts and the ability to add links, video, and images. Mindomo is well suited for exploring new topics, collecting research, & planning for writing. The students and classrooms that I have been working with have been using it to research Science topics, collect & display poetry and to plan for speech writing.
