This project harnesses the power of GPT-4 LLM to translate eBooks from any language into your preferred language, maintaining the integrity and structure of the original content. Imagine having access to a vast world of literature, regardless of the original language, right at your fingertips.

This tool not only translates the text but also carefully compiles each element of the eBook – chapters, footnotes, and all – into a perfectly formatted EPUB file. We use the gpt-4-1106-preview (GPT-4 Turbo) model by default to ensure high-quality translations. However, we understand the need for flexibility, so we've made it easy to switch models in main.py according to your specific needs.

To install the necessary components for our project, follow these simple steps:

pip install -r requirements.txt
cp config.yaml.example config.yaml

Remember to add your OpenAI key to config.yaml.

Our script comes with a variety of parameters to suit your needs. Here's how you can make the most out of it:

Before diving into translation, it's recommended to use the show-chapters mode to review the structure of your book:

python main.py show-chapters --input yourbook.epub

This command will display all the chapters, helping you to plan your translation process effectively.

To translate a book from English to Polish, use the following command:

python main.py translate --input yourbook.epub --output translatedbook.epub --config config.yaml --from-lang EN --to-lang PL

For more specific needs, such as translating from chapter 13 to chapter 37 from English to Polish, use:

python main.py translate --input yourbook.epub --output translatedbook.epub --config config.yaml --from-chapter 13 --to-chapter 37 --from-lang EN --to-lang PL

For books in AZW3 format (Amazon Kindle), use Calibre (https://calibre-ebook.com) to convert them to EPUB before using this tool.

Amazon eBooks (AZW3 format) are encrypted with your device's serial number. To decrypt these books, use the DeDRM tool (https://dedrm.com). You can find your Kindle's serial number at https://www.amazon.com/hz/mycd/digital-console/alldevices.

We warmly welcome contributions to this project! Your insights and improvements are invaluable. Currently, we're particularly interested in contributions in the following areas:

• Support for other eBook formats: AZW3, MOBI, PDF.
• Integration of a built-in DeDRM tool

Join us in breaking down language barriers in literature and enhancing the accessibility of eBooks worldwide!
