GitMind is a collaborative mind mapping tool. You can invite people to work on your mind maps with you by sending them an email or by sharing a link and private access code.
My favorite design aspect of GitMind is the option to quickly turn your mind map into a linear, bullet point outline. The best thing is that you can toggle back and forth between the mind map view and the outline view as much as you like without affecting any elements of your mind map's design.
As you would expect of any good mind mapping tool, GitMind offers plenty of tools for customizing the organization and color scheme of your mind maps. You can make wholesale changes to your mind map's color scheme by choosing a predefined theme. Minor color scheme changes can be made by selecting individual nodes and lines then choosing a different color, line thickness, font type, font color, and font size.
GitMind can be used in your web browser. Free GitMind Android and iOS apps are also available.Applications for Education
GitMind's best feature for teachers and students is the option to quickly switch between mind map views and linear outline views. I've always liked having that option in a mind mapping tool because while some students like seeing the mapped connections between ideas other students prefer to have them listed in bullet points. GitMind satisfies the needs of both types of students.
