Next AI Draw.io

A next.js web application that integrates AI capabilities with draw.io diagrams. This app allows you to create, modify, and enhance diagrams through natural language commands and AI-assisted visualization.

Features

• LLM-Powered Diagram Creation: Leverage Large Language Models to create and manipulate draw.io diagrams directly through natural language commands
• Image-Based Diagram Replication: Upload existing diagrams or images and have the AI replicate and enhance them automatically
• Diagram History: Comprehensive version control that tracks all changes, allowing you to view and restore previous versions of your diagrams before the AI editing.
• Interactive Chat Interface: Communicate with AI to refine your diagrams in real-time
• Smart Editing: Modify existing diagrams using simple text prompts
• Targeted XML Editing: AI can now make precise edits to specific parts of diagrams without regenerating the entire XML, making updates faster and more efficient
• Improved XML Handling: Automatic formatting of single-line XML for better compatibility and reliability

How It Works

The application uses the following technologies:

• Next.js: For the frontend framework and routing
• @ai-sdk/react: For the chat interface and AI interactions
• react-drawio: For diagram representation and manipulation

Diagrams are represented as XML that can be rendered in draw.io. The AI processes your commands and generates or modifies this XML accordingly.

Getting Started

Installation

1. Clone the repository:

git clone https://github.com/DayuanJiang/next-ai-draw-io
cd next-ai-draw-io

1. Install dependencies:

npm install
# or

1. Create a .env.local file in the root directory with the following variables:

OPENAI_API_KEY=your_openai_api_key_here
# Add any other required environment variables

1. Run the development server:

npm run dev

1. Open http://localhost:3000 in your browser to see the application.

TODOs

• Allow the LLM to modify the XML instead of generating it from scratch everytime.
• Improve the smoothness of shape streaming updates.
