Coggle is a collaborative mind-mapping tool that helps you make sense of complex things. Create unlimited mind maps and easily share them with friends and colleagues.
There is no shortage to mind mapping software, and here’s another one, Coggle. With Coggle, users can participate in the collaborative process on creating and editing a mind map. The free version limits you to 1 private diagram and unlimited public diagrams (although once logged in, it said I had 1 of 3 private diagrams, so maybe they are changing that).
Signing up requires a Google account, which is nice for G Suite schools, but not so nice for non-G Suite schools.
Blocks can include text and graphics, plus, there is a built in icon library you can use. Unfortunately, once you add a graphic object to a box, there is Markdown formatting that might throw a person off.
All in all, Coggle looks pretty cool, and works very well.
