what AI can build

Build an outliner tree in React supporting Tab/Shift+Tab nesting, drag reordering, and instantaneous Canvas mindmap rendering.

An outliner note editor with automatic mindmap tree generation and local JSON/markdown storage is a proven, reliable one-sitting solo build; cloud multi-platform sync and advanced PDF/image export pipelines remain tied to the membership.

The prompt was editor-reviewed; no completed build is recorded.

the prompt

Curated prompt

Build a personal outliner note editor with one-click mindmap visualization in TypeScript and React.
Requirements:
- Tree outliner editor: press Enter to create a new item, Tab to indent (make child), Shift+Tab to outdent (make parent), and Backspace on empty to delete.
- Node manipulation: drag-and-drop to reorder items; fold/unfold disclosure bullets.
- Mindmap view: toggle between Outline View and Mindmap View; draw nodes and connectors dynamically using HTML5 Canvas or SVG.
- Local storage: persist the hierarchical JSON data in localStorage or IndexedDB.
- Export: download notes as clean Markdown or high-resolution PNG mindmap images.
- Completely self-contained, client-side only, no external tracking or accounts.
