Thinknode

ThinkNode – Collaborative Mind Mapping & Concept Maps
ThinkNode is a powerful, modern tool for building and sharing mind maps, concept maps, and visual knowledge structures — alone or in real time with others.
Enjoy complete creative freedom on an infinite, zoomable canvas. Drag and drop nodes freely, resize them, choose shapes (circle, rectangle, rounded rectangle), pick any color, and edit text directly inside each node. Connect ideas with customizable arrows — straight or curved, single- or double-headed, solid or dashed — and add descriptive labels to connections.
Collaborate seamlessly with friends, classmates, or colleagues. Multiple users can edit the same map simultaneously with live cursors, instant updates, role-based permissions (Owner, Editor, Viewer), and easy sharing via link or email invitation.
Every map is automatically saved with version history. Work offline with automatic sync when you reconnect. Export your maps as high-quality PNG images or vector-ready PDFs in seconds.
