A possible way such a system could work is as follows: The user uploads a book in PDF, EPUB, or TXT format. The system then extracts the text and breaks it into sections, usually by chapters or smaller blocks, to make it easier for the AI to process. Each section is translated by the AI while keeping terms and style consistent. After translation, the sections are merged back together in the correct order, and the final result can be exported again as a TXT, PDF, or EPUB file. In short: upload, split, translate, merge, and export.
