Mind Map Editor: Offline HTML — Nodes, Branches, Export

A REAL MIND MAP EDITOR IN ONE FILE — NO SIGN-UP, NO INTERNET

Build a hierarchy of ideas: branches and sub-branches of any depth, rename with a double click, drag nodes, automatic tree layout and branch collapsing. Export to JSON and Markdown, autosave in the browser.

EXAMPLE FROM THE SCREENSHOT (real calculation of the program):
• A map of 17 nodes: 4 branches with 3 sub-branches each + root
• Tree depth: 3 levels
• Connections drawn automatically with Bezier curves

WHAT´S INSIDE (one index.html file):
• Add branches to a selected node, delete with the whole subtree
• Rename with a double click, 80-character limit
• Drag nodes with the mouse, automatic layout by levels
• Collapse branches with a counter of hidden nodes
• Export to JSON (with coordinates) and import back
• Export to Markdown for Notion and documents
• Autosave and load from localStorage

WHO IT´S FOR:
Students, product managers, course authors and writers. Online mind map services require sign-up and a subscription, and free ones limit the node count — here everything is yours and offline.

FORMAT: one HTML file, works offline. Instant file delivery after payment.
