Connected Mind is a free mind mapping tool that you can find in the Google Chrome Web Store. Using Connected Mind you can create free-form mind maps or use a template. A lot of mind mapping tools lock you into using straight lines between elements, but Connected Mind is not one of them. Connected Minds allows you to create mind maps in any configuration that you like. As it is a Chrome Web Store app, Connected Mind allows you to save your work online using your Google Account credentials. The video below offers a demonstration of Connected Minds (there is not any sound in the video).

Applications for Education
Connected Mind could be a good app for students to use to develop mind maps from scratch or from an existing image or file they upload. In general, I find mind mapping to be a great exercise for students to do while planning a video project. I also use mind mapping when planning a lesson unit for my courses.
