# QuizFlash 🚀

An intelligent quiz generation platform powered by AI that creates customizable educational questions from any source material.

## Features

- **Multiple Question Types**: Support for multiple choice, cloze (fill-in-the-blank), grammar check, reading comprehension, and essay questions
- **AI-Powered Generation**: Uses OpenAI GPT-4 to generate high-quality, educational questions
- **Configurable Parameters**: Each question type has customizable difficulty levels and specific parameters
- **Source Material Support**: Generate questions based on your own text content
- **Real-time Question Bank**: Build and manage a collection of generated questions
- **Modern UI**: Clean, responsive interface built with Next.js and Tailwind CSS

## Getting Started

First, run the development server:

```bash
npm run dev
# or
yarn dev
# or
pnpm dev
# or
bun dev
```

Open [http://localhost:3000](http://localhost:3000) with your browser to see the result.

You can start editing the page by modifying `app/page.tsx`. The page auto-updates as you edit the file.

### Flow Description

#### 1. Configuration Layer
- **Question Config**: Abstract configuration system that defines parameter schemas for each question type
- **Parameter Form**: Dynamically renders form fields based on the configuration
- **Parameter Input**: Reusable input components (select, range, input, checkbox)

#### 2. User Interaction Layer
- **User Input**: Users interact with dynamically generated parameter forms
- **Parameters Object**: Collects user preferences (difficulty, number of options, etc.)
- **Question Type Selection**: Users choose from available question types
- **Source Material**: Optional text input to provide context for questions

#### 3. API Processing Layer
- **Generate Question**: API endpoint processes the generation request
- **Prompt Templates**: Pre-defined, configurable templates for each question type
- **Template Rendering**: Dynamic substitution of user parameters into prompt templates
- **Final Prompt**: Complete, contextualized prompt ready for AI processing

#### 4. AI Generation Layer
- **AI Processing**: OpenAI GPT-4 Mini generates questions based on the prompt
- **Zod Schema Validation**: Ensures AI responses match expected structure
- **Structured Response**: Clean, validated JSON object containing question data

#### 5. Display Layer
- **Question Bank**: State management for storing and organizing generated questions
- **Question Card**: UI components for rendering individual questions
- **User Display**: Final question bank interface with selection and management features

### Key Architecture Benefits

- **🔧 Configurable**: Adding new question types requires only configuration changes
- **♻️ Reusable**: Components work across all question types
- **🛡️ Type-Safe**: Full TypeScript support throughout the entire flow
- **📦 Modular**: Clean separation of concerns between layers
- **🚀 Scalable**: Easy to extend with new features and question types

## Tech Stack

- **Frontend**: Next.js 14, React, TypeScript, Tailwind CSS
- **AI Integration**: OpenAI GPT-4 Mini, Vercel AI SDK
- **Validation**: Zod schema validation
- **Styling**: Tailwind CSS with dark mode support
- **State Management**: React hooks and context

## Adding New Question Types

Thanks to the abstract configuration system, adding new question types is incredibly simple:

1. Add configuration to `src/types/questionConfig.ts`:
```typescript
'your-new-type': {
  id: 'your-new-type',
  parameters: [
    {
      key: 'difficulty',
      label: 'Difficulty Level',
      type: 'select',
      defaultValue: 'intermediate',
      options: [
        { value: 'beginner', label: 'Beginner' },
        { value: 'intermediate', label: 'Intermediate' },
        { value: 'advanced', label: 'Advanced' },
      ],
    },
    // Add more parameters as needed
  ],
}
```

2. That's it! No component modifications required. The UI will automatically render the appropriate form fields.
