ChatGPT draws the finished pages and a matching cover; Paperkin assembles them into a physical book you can preview and order. You can also bring your own original page artwork or photos.\n\nCreate several pages in a single image, then let Paperkin cut the page sheet into individual pages in reading order. Browse the real front cover, every interior page, and the back cover. Refine the artwork, change the page order, replace a page, or update the dedication. Each revision saves a separate preview.\n\nPaperkin supports printed picture books and photo books. It does not create typeset cookbooks, journals, coloring books, long-form text books, EPUBs, or digital subscriptions.\n\nWhen the preview is ready, choose an available binding, quantity, and shipping destination on Paperkin's website. You approve and pay through external checkout; the plugin cannot charge a card or place an order. Lulu prints and ships the book. Checkout supports 1\u201330 copies per order; contact support for larger quantities.\n\nSold by Lora Labs AB. Available bindings, page counts, print resolution, prices, and delivery countries depend on the book. Use original artwork or images you have permission to print.",
