Can I see how my book's pages will look before exporting?

Yes. In the Book design card, next to the Trim size selector, click Page preview. BookyAI renders your actual print PDF — real page size, real page breaks, real typography — and opens it in your PDF viewer. It's not an approximation: it is the same engine that produces your final PDF export, so what you see is exactly how the book will lay out. Use it to check a trim size or design template before committing to a full export.
