Mind Map Generator Plugin

A powerful mind map generation plugin that converts Markdown text into beautiful PNG mind maps and can also use a selected LLM model to summarize plain text into mind map Markdown first. Supports center radial, horizontal, and free layouts, with perfect Chinese environment compatibility. Local Markdown rendering does not require an API key; the AI Mind Map tool uses the LLM model selected in Dify.

Core Features

Triple Layout Support

• Center Radial Layout: Classic radial mind maps, perfect for knowledge systems and concept relationships

  

• Horizontal Layout: Left-to-right hierarchical expansion, ideal for processes and timelines

  

• Smart Free Structure Layout: Automatically analyzes content complexity and tree depth to choose the best layout (Center Radial for simple/conceptual maps, Horizontal for deep/complex hierarchies).

AI Mind Map (New in v0.0.8)

The AI Mind Map tool lets users choose an LLM model in Dify, input plain text, and generate a mind map automatically:

• LLM Model Selection: Uses Dify model-selector, so the workflow user can choose any available LLM model.
• Automatic Markdown Summary: Converts long plain text into concise mind map Markdown.
• Layout Mode: Supports center, horizontal, and free output modes.
• Optional MD Download: Can output the AI-generated Markdown file together with the PNG image.

Watermark Support (New in v0.0.6)

Add custom watermarks to your mind maps with extensive customization options:

• Watermark Text: Custom text content (Required)
• Opacity: Adjustable transparency (0-255)
• Layout Options:
  • Full Screen Tile (default)
  • Four Corners
  • Center
  • Individual Corners (TL, TR, BL, BR)
• Layering: Watermark is always placed in the background for better readability.

Perfect Chinese Support

• Built-in 18.79MB Chinese font file ensures perfect rendering in server environments
• Multi-platform font detection and fallback mechanisms
• Display effects optimized specifically for Chinese users

Intelligent Optimization

• Dynamic Size Adjustment: Intelligently adjusts canvas and font size based on content complexity
• Anti-overlap Algorithm: Advanced collision detection ensures clear, readable text
• Memory Optimization: 100MB memory limit with efficient resource management

Technical Advantages

• Local Rendering: Markdown-to-PNG rendering runs locally, no external mind map service required
• Privacy-aware Workflow: Markdown rendering is local. The AI Mind Map tool sends text_content only to the LLM model selected in Dify.
• Pure Python Implementation: No external dependencies like Node.js required
• High-Quality Output: 150 DPI PNG images with Bézier curve smooth connections
• Multi-platform Compatibility: Full support for Windows, macOS, and Linux

Tools

ai_mind_map

Generate a mind map from plain text with the help of a selected LLM model.

Parameter	Required	Description
model_config	Yes	LLM model selected in Dify.
text_content	Yes	Plain text to summarize into a mind map.
layout_mode	No	center, horizontal, or free. Default: free.
filename	No	Output PNG filename without extension.
download_md	No	Output the AI-generated Markdown file as well. Default: false.

Example:

text_content: Paste a product requirement, meeting notes, article, or study material.
layout_mode: free
download_md: true

The tool first asks the selected LLM to generate clean mind map Markdown, then renders the PNG locally.
