What is AI Book Translate?

AI Book Translate is a translation tool designed specifically for book-length documents. It uses a five-pass refinement system to improve translation quality with each iteration, rather than relying on a single translation pass. The tool accepts common document formats (.txt, .md, .docx) and allows you to upload and manage custom glossaries, which helps maintain consistent terminology throughout your book. It targets authors and publishers working with nonfiction content who need translations that require minimal post-editing before publication. The service aims to produce output ready for print or digital release without extensive manual revision.
