MindMup is an online application helping users create, share and publish mind maps, hassle-free. With MindMup, you can brainstorm, take meeting notes, create presentations and outline documents with mind maps, and publish your ideas online and to social networks.The MindMup Slack app helps you share maps created in MindMup more easily with collaborators in Slack channels. It will automatically generate a preview with a thumbnail and the basic information about the map, so that other workspace members see easily what your map is about, and quickly spot the relevant map when searching through old messages.The current version supports sharing public free maps. We will soon be adding support for private Gold maps and maps stored on Google Drive.
