-# AnkiAI
+# AnkiAI - Automated Anki Deck Creator
 
-AnkiAI is a robust system that converts images containing text into structured Anki cards using Optical Character Recognition (OCR) and OpenAI's GPT-4 language model. Users can quickly generate decks of flashcards from their images for effective study.
+AnkiAI is a tool that leverages OCR (Optical Character Recognition) and GPT-3's powerful natural language processing capabilities to automatically generate Anki decks from images containing text.
 
-## Features
-- Converts image content to textual content using OCR.
-- Uses OpenAI's GPT-4 model to structure the content into Anki decks and cards.
-- Outputs the structured content as an Anki package.
+### Overview
 
-## Dependencies
-- genanki: Used for creating Anki decks and cards.
-- Pillow: Image processing library.
-- openai: API library for OpenAI's GPT-4 model.
-- flask: Web server to host the service.
+- AnkiAI is designed to streamline the process of creating Anki decks from images.
+- The core idea is to use OCR to extract text from images and then use GPT-3 to transform this text into a structured Anki deck format.
+- Users can make a POST request to a Flask server endpoint with their images to receive the Anki deck (.apkg file).
 
-## Setup and Installation
+### Directory Structure
+
+- `.vscode/`: Contains configuration for VSCode debugger for Flask applications.
+- `ankiai.py`: The main script that drives the creation of Anki decks from images.
+- `constants.py`: Contains constant variables used across the project.
+- `deck_creation.py`: Contains logic for communicating with OpenAI's API and deck creation using genanki.
+- `image_processing.py`: Processes images, converting them for OCR and then performing OCR to extract text.
+- `logging_config.py`: Logging configuration for the entire project.
+- `server.py`: Flask server that provides an API endpoint to upload images and get back an Anki deck.
+
+### Requirements
+
+#### ImageMagick
+
+ImageMagick is a software suite that allows you to create, edit, and compose bitmap images. It can read, convert, and write images in a variety of formats (over 100) including DPX, EXR, GIF, JPEG, JPEG-2000, PDF, PhotoCD, PNG, Postscript, SVG, and TIFF. In the AnkiAI project, it is used for preprocessing images to improve the performance of OCR.
+
+```bash
+sudo apt-get update
+sudo apt-get install imagemagick
+```
+
+#### Tesseract
+
+You need Tesseract for the OCR functionality:
+
+```bash
+sudo apt-get install tesseract-ocr
+```
+### Python Dependencies
+
+To ensure consistent functionality, it's crucial to use the provided `requirements.txt` file which pins dependencies to known compatible versions.
+
+You can install the Python dependencies via `pip` using the `requirements.txt` file:
+
+```bash
+pip install -r requirements.txt
+```
+
+### How to Run
+
+1. **Environment Variables**: Make sure to set the `OPENAI_API_KEY` environment variable to your OpenAI API key.
 
-1. Clone this repository:
    ```bash
-   git clone https://git.rudefox.io/bj/anki-json2ankicards.git
-   cd json2ankicards
+   export OPENAI_API_KEY=sk-myapikey
    ```
 
-2. Set up a virtual environment and activate it:
-   ```bash
-   python3 -m venv venv
-   source venv/bin/activate
-   ```
+2. **Run the Flask server**:
 
-3. Install the required packages:
-   ```bash
-   pip install -r requirements.txt
-   ```
-
-4. Set up the OpenAI API key:
-    ```bash
-    export OPENAI_API_KEY=your_openai_api_key
-    ```
-
-5. Run the server:
    ```bash
    python server.py
    ```
 
-## Usage
+   This will start the Flask server. You can then make a POST request to `http://localhost:5000/deck-from-images` with your images to get an Anki deck.
 
-1. Start the server as mentioned above.
+3. **Run Directly**:
 
-2. Use a tool like [Postman](https://www.postman.com/) or `curl` to send images to `http://localhost:5000/deck-from-images` as a multi-part POST request.
+   If you prefer not to use the Flask server, you can also run `ankiai.py` directly:
 
-3. The server will respond with a downloadable Anki package. Import this into your Anki app and start studying!
+   ```bash
+   python ankiai.py <directory_path_containing_images>
+   ```
 
-## Modules
+### Example curl commands to interact with the service:
 
-1. **ankiai.py**: The main module that orchestrates the flow.
-2. **images2text.py**: Converts image content into text using OCR.
-3. **json2deck.py**: Converts structured JSON data into an Anki package.
-4. **prompt4cards.py**: Uses OpenAI to structure the content into Anki decks and cards.
-5. **server.py**: Flask server to host the service.
+You can make POST requests to the server using curl. Here are some examples from the command line history:
 
-## Contributing
+```bash
+curl -X POST -o deck.apkg \
+-F "image=@/home/ubuntu/Pictures/image1.png" \
+-F "image=@/home/ubuntu/Pictures/image2.png" \
+-F "image=@/home/ubuntu/Pictures/image3.png" \
+http://localhost:5000/deck-from-images
+```
 
-Contributions are welcome! Please submit a pull request or open an issue to discuss changes or fixes.
+Batch processing of images:
 
-## License
+```bash
+for file in /home/ubuntu/Pictures/*; do 
+    if [[ -f "$file" ]]; then 
+        basefile=$(basename "$file");
+        curl -X POST -o "deck-${basefile}.apkg" -F "image=@${file}" http://localhost:5000/deck-from-images;
+    fi;
+done
+```
 
-[MIT License](LICENSE)
+### How to Debug (VSCode Users)
+
+- Open the project in VSCode.
+- Set up your breakpoints.
+- Use the VSCode debugger and select "Python: Flask" to start debugging the Flask server.
+
+### Important Notes
+
+- **API Key**: For the project to work, it is essential to have the `OPENAI_API_KEY` environment variable set.
+- **Image Types**: Currently, the image processing module supports PNG, JPG, and JPEG formats.
+- **Output**: The output `.apkg` file (Anki package file) will be named `out.apkg`.
+
+### Acknowledgements
+
+This project heavily relies on the `openai` library for processing and the `genanki` library for deck generation.
+
+### Contributions
+
+Contributions are always welcome. Please create a new issue or a pull request for any bug fixes or feature requests.
