│ NodeTool uses a node-based visual interface where each node    │
│ represents an AI operation. Users connect nodes by dragging    │
│ edges between them. The tool handles:                          │
│ • Type-safe connections between nodes                          │
│ • Local execution engine (Python-based backend)                │
│ • Real-time workflow execution with live preview               │
│ • Model management for local LLMs (MLX, GGML/GGUF)            │
│ • Integration with cloud APIs (OpenAI, Anthropic, etc.)       │
│                                                                 │

│ ──────────────────────────────────────                        │
│ vs ComfyUI: ComfyUI focuses on image generation. NodeTool     │
│ extends this to general AI workflows including LLMs, RAG,      │
│ audio, and video.                                              │

│ visual interface with no coding required.                      │
└─────────────────────────────────────────────────────────────────┘
```

**Key Purpose:**
- ✅ Provides complete, quotable answers for LLMs
- ✅ Structured with semantic HTML
- ✅ Includes explicit comparisons
- ✅ Hidden from visual display but crawlable by search engines

## 5. Metadata Changes

### Page Title
**Before:** `NodeTool | Visual AI Workflow Builder — Local, Open-Source, Node-Based`  
**After:** `NodeTool: Node-Based Visual Builder for AI Workflows and LLM Agents`

### Meta Description
**Before:**
```
The open-source visual workflow builder for AI. Combine the generative power 
of ComfyUI with the automation ease of n8n. Build LLM agents, RAG systems, 
and multimodal pipelines locally.
```

**After:**
```
NodeTool is an open-source visual programming tool for building AI workflows. 
Run locally on macOS, Windows, or Linux. Connect LLMs, create RAG systems, 
build AI agents, and process multimodal content through a drag-and-drop node 
interface. Alternative to ComfyUI for general AI and n8n for AI-specific 
automation.
```

---

## 6. JSON-LD Structured Data

### SoftwareApplication Schema
**Added/Enhanced:**
- ✅ 12 concrete features (was: 8 generic)
- ✅ `softwareRequirements`: "Python 3.10 or higher"
- ✅ `applicationSubCategory`: "AI Development Tool"
- ✅ `license` URL
- ✅ `installUrl`

### NEW: FAQPage Schema
**7 Question-Answer Pairs:**
1. What is NodeTool?
2. How is NodeTool different from ComfyUI?
3. How is NodeTool different from n8n?
4. Does NodeTool require cloud services?
5. What AI models does NodeTool support?
6. Who should use NodeTool?
7. Is NodeTool open source?

## Font Improvements

### Before
```css
body {
  font-family: var(--font-inter), system-ui, -apple-system, 
    BlinkMacSystemFont, "Segoe UI", sans-serif;
}
```

### After
```css
body {
  font-family: var(--font-inter), -apple-system, BlinkMacSystemFont, 
    "Segoe UI", "Helvetica Neue", Arial, "Noto Sans", sans-serif, 
    "Apple Color Emoji", "Segoe UI Emoji", "Segoe UI Symbol", 
    "Noto Color Emoji";
}
```

**Benefits:**
- ✅ Better fallback font stack following modern best practices
- ✅ Includes emoji support
- ✅ Covers more systems and languages (Noto Sans)
- ✅ Graceful degradation when Google Fonts unavailable

---
