Nimbalyst Mindmap

Nimbalyst Mindmap is a canvas-first mindmap editor for Nimbalyst. It stores maps as markdown-based .mindmap files, so the same document stays readable in plain text, editable in source mode, and usable from AI tooling.

Highlights

• Freeform spatial editing on an infinite canvas
• Markdown-backed .mindmap files with a simple, readable structure
• Outline-style hierarchy plus node metadata, notes, tags, and status
• AI tools and Claude plugin support for creating and editing mindmaps

File Format

.mindmap files are standard markdown with one root heading, optional frontmatter, and nested structure built from headings and lists. See examples/ and the Claude skill in claude-plugin/ for format examples.

Development

Requirements:

• Node.js 20 or newer
• A compatible Nimbalyst build
• @nimbalyst/extension-sdk

Local commands:

npm install
npm test
npm run build

This repository contains the standalone extension source. If you are working from the main Nimbalyst project, use that project's extension build and marketplace publishing workflow.

For extension-specific development notes, see CLAUDE.md.
