An easy to use mind mapping site, with a very intuitive interface. You can choose different colours for each strand of your mind map, the text size can be altered, links can be added and videos embed when you add a video link, you can also add images.
Finished maps can be downloaded as PDF or PNG or shared via a link on social media.
I particularly like that you can work collaboratively on your mind maps by adding additional authors, comments can also be added, could also be a useful tool in organising ideas related to project based learning.
An added bonus for those who use use Google can log in with your Google account.
