🚀 Quick Start

Prerequisites

• Node.js 18+ (Download)
• Pandoc (required for perfect DOCX export) (Download)

Installation

# Clone the repository
git clone https://github.com/yourusername/ai-doc-converter.git
cd ai-doc-converter/web-app

# Install dependencies
npm install

# Start development server
npm run dev

Open http://localhost:3000 in your browser.

📦 Setting Up Pandoc (Required for DOCX)

Pandoc is required for generating Word documents with perfect mathematical equations.

1. Install Pandoc:

   • Windows: winget install pandoc (or download from website)
   • macOS: brew install pandoc
   • Linux: sudo apt install pandoc

2. Verify Configuration: The application tries to find Pandoc automatically. If you installed it in a custom location or it's not found:

   • Open app/api/convert/route.ts
   • Look for the pandocPaths array
   • Update the path with your username:

     'C:\\Users\\YOUR_USERNAME\\AppData\\Local\\Pandoc\\pandoc.exe',

   • Restart the server (npm run dev) after changes.

🐳 Docker (Alternative)

If you don't want to install Pandoc locally, use Docker:

# Build and run with Docker
docker build -t ai-doc-converter .
docker run -p 3000:3000 ai-doc-converter

⚠️ Known Limitations & Community Notes

• PDF Export: The PDF export feature has been removed from the core to simplify the project.
  • Contribution Opportunity: If you want PDF export, you can implement it using wkhtmltopdf or by re-enabling LaTeX support. See app/api/convert/route.ts for where conversion logic lives.
• Text Alignment: Markdown doesn't support text alignment (center, right) by default.
• Underline: Uses HTML <u> tag.

🔧 How It Works

Math Rendering (Preview)

1. Raw LaTeX (e.g., \vec{a} \times \vec{b}) is detected
2. Delimiters are normalized (\( → $, \[ → $$)
3. KaTeX renders beautiful equations in the browser

DOCX Export (Pandoc)

1. Frontend sends markdown to /api/convert
2. Server writes content to temp file
3. Pandoc converts: markdown → docx with full LaTeX support (equations become editable Word math regions)
4. Generated DOCX is streamed back to browser
