Choosing Between Mind Map Sites

Mind map sites are web tools for drawing ideas as a branching diagram. A central topic sits in the middle, with main ideas as branches and details as smaller sub-branches. Most sites offer a blank canvas where you add nodes by hand. Some also let you start from a template or import notes, which saves time when you already have material to organize.

Blank canvas: place and connect nodes yourself
Templates: start from a ready structure and adapt it
File import: build a map from documents or slides
Export and sharing: save as PNG or PDF, or send a link

Use a mind map to plan an essay, revise a unit or outline a project. To make a map from your own notes, try CogniGuide's AI generator.
