The tool offers seven different mindmap structures to choose from: Hierarchical, Radial, Spider, Flow Chart, Concept Map, Timeline, and Organic. Each structure serves different purposes – Hierarchical is great for showing clear relationships, Radial works well for central themes, Spider maps are ideal for brainstorming, Flow Charts show processes, Concept Maps illustrate relationships, Timeline structures work for chronological content, and Organic structures offer a more natural flow.
