Create mind-maps to brainstorm or organize ideas for projects or essays. Bubbl.us provides a quick and easy platform for creating a digital mind-map just like Popplet. Simply click “Start Brainstorming” to get started. You can export your work as a .jpg to save it or you can print it out. A box will pop up every few minutes asking you to create an account to save your work, which is a bit annoying, but you can just exit out of this box and continue working. Also, the Sign Up box stays on your screen at all times, also annoying. (FYI, Popplet does not have these two annoying features) You only have to create an account in order to save unfinished work to continue later. You can make up to 3 mind-maps as a free user once you create an account.
