# Text Converter Flow

This project demonstrates an interactive text transformation tool built with PocketFlow.

## Features

- Convert text to UPPERCASE
- Convert text to lowercase
- Reverse text
- Remove extra spaces
- Interactive command-line interface
- Continuous flow with option to process multiple texts

## Getting Started

1. Install the required dependencies:

```bash
pip install -r requirements.txt
```

2. Run the application:

```bash
python main.py
```

## How It Works

The workflow features an interactive loop with branching paths:

```mermaid
graph TD
    Input[TextInput Node] -->|transform| Transform[TextTransform Node]
    Transform -->|input| Input
    Transform -->|exit| End[End]
    Input -->|exit| End
```

Here's what each part does:
1. **TextInput Node**: Collects text input and handles menu choices
2. **TextTransform Node**: Applies the selected transformation to the text

## Example Output

```
