# AI Language Note Organizer

This project is a command-line application that uses the Google Gemini API to automatically organize your language class notes. It takes a directory of markdown files, identifies common themes and topics, and generates a single, well-structured markdown file with your notes grouped under relevant headings.

## Features

- **Recursive File Scanning:** Automatically scans through nested directories to find your note files.
- **Flexible Filtering:** Use a simple text pattern to specify which notes to process (e.g., "Japanese" or "Spanish_Class").
- **AI-Powered Organization:** Leverages the Gemini API to intelligently categorize and structure your notes.
- **Non-Destructive:** Your original note files are never modified.

## Installation

1. **Clone the repository:**
   ```bash
   git clone https://github.com/your-username/language-note-organizer.git
   cd language-note-organizer
   ```

2. **Install the dependencies:**
   ```bash
   npm install
   ```

3. **Set up your environment variables:**
   - Create a `.env` file in the root of the project.
   - Add your Google Gemini API key to the `.env` file:
     ```
     GEMINI_API_KEY=your_api_key_here
     ```

## Usage

Run the application from your terminal with the following command:

```bash
node index.js <directory_path> [file_pattern]
```

- `<directory_path>`: The path to the folder containing your note files.
- `[file_pattern]` (Optional): A keyword or pattern to filter the files. Only files with names containing this pattern will be processed.

### Example

Imagine you have a `notes/` directory with the following structure:

```
notes/
├── japanese/
│   ├── 2023-10-26_Japanese_Grammar.md
│   └── 2023-10-27_Japanese_Vocab.md
└── spanish/
    └── 2023-11-01_Spanish_Phrases.md
```

To organize only the Japanese notes, you would run:

```bash
node index.js notes/ japanese
```

The script will create a new file named `organized_notes.md` in the project's root directory with the organized content from your Japanese notes.
