create_coloring_book
ChatGPTFor a creative or illustrated brief, first call plan_book_design to load the design skill, plan the full page budget and prepare real artwork. Once the content and artwork are ready: Create a real physical coloring book, personalized with a name. Use the catalog theme or supply 8–24 original black-outline coloring images uploaded or generated in this chat; choose the closest catalog theme for its cover if no cover artwork is supplied. Covers can use generated color artwork. This creates a printable book preview, not an image-generation request. Do not use for loose pages to print at home.
create_cookbook
ChatGPTFor a creative or illustrated brief, first call plan_book_design to load the design skill, plan the full page budget and prepare real artwork. Once the content and artwork are ready: Create a physical cookbook with editorial front matter, numbered contents, full-page photography or illustrations paired with recipes, readable ingredient/method columns, and kitchen notes. Accepts actual uploaded or chat-generated image files. Pass every recipe with ingredients and steps; use image_caption to label ingredient studies or generated illustrations honestly. Prints in full color. Do not use for a single recipe card or a meal plan without recipes.
create_custom_book
ChatGPTFor a creative or illustrated brief, first call plan_book_design to load the design skill, plan the full page budget and prepare real artwork. Once the content and artwork are ready: Use for individually designed books beyond the built-in layouts: poems, illustrated stories, comics, workbooks, portfolios or any creative brief. Author every cover/interior page as measured textBox, rect, rule and image blocks; no aesthetic preset is required. Coordinates are points from the top left. Use 36pt safe margins for text. Available print sizes: story_book/journal 432×648pt (B&W interiors), cookbook/coloring_book 612×792pt (cookbook color, coloring B&W), photo_book 612×612pt (color). These are physical print packages; cookbook/photo_book can contain any custom content. Covers always color. Interior colors/images are rendered in grayscale for B&W packages. If the brief specifies colored interior backgrounds (including cream or pale blue), typography or artwork, choose cookbook/photo_book from the start; never claim a B&W preview preserves those colors. Keep full text, compose continuations instead of deleting overflow. Use actual uploaded/generated image files with named keys, no SVG markup/remote URLs inside blocks. The plan contains front/back covers separately from ordered interior pages. Short interiors gain the selected useful padding to meet binding minimums. Show the actual preview and inspect all pages before ordering.
create_journal
ChatGPTFor a creative or illustrated brief, first call plan_book_design to load the design skill, plan the full page budget and prepare real artwork. Once the content and artwork are ready: Use this when the user wants a printed journal, diary, notebook or guided journal with their own title and, optionally, a writing prompt at the top of each page. Do not use for books of finished text; use create_story_book for those.
create_photo_book
ChatGPTFor a creative or illustrated brief, first call plan_book_design to load the design skill, plan the full page budget and prepare real artwork. Once the content and artwork are ready: Use this when the user wants pictures they attached or made in this chat printed as a physical photo book, one picture per page with optional captions. Requires the image files. Do not use without images, and do not use for pictures the user has no right to print.
create_picture_book
ChatGPTUse this when the user wants a printed picture book, comic or early reader drawn with ChatGPT's image generation, or made from uploaded images. Best: page sheets, each one image of 8 equal square pages (4 columns × 2 rows on a wide 2:1 image) with plain white gutters, passed with grid, plus a separate square (1:1) cover_image. One square image per page also works. Pages are flat finished artwork with their words drawn in, not a mockup of a book, page, screen or desk, with no page curl, shadow, border or page numbers. Keep every letter 15% inside each page and check every word. Prints in full color on 8.5×8.5 in pages. Captioned photo albums: create_photo_book.
create_story_book
ChatGPTFor a creative or illustrated brief, first call plan_book_design to load the design skill, plan the full page budget and prepare real artwork. Once the content and artwork are ready: Create a physical story, poems, letters, memoir or text book. Pass the final text in chapters, and optionally cover art and chapter illustrations uploaded or generated in this chat. Covers print in color; chapter illustrations print in black and white. This creates a real designed book preview, not an image mockup. Do not use for recipes, journals or photo collections.
get_book
ChatGPTUse this when the user asks about a book preview created earlier in this conversation, such as its formats, prices or order link. Requires the book_id returned when it was created.
get_book_design
ChatGPTBefore refining ANY book, retrieve its exact saved source_content, custom page plan when present, stable page IDs and image keys. Standard recipes and chapters are included so feedback never requires recreating text from memory. Preserve unrequested text, images and pages. Reuse asset keys in revisions; private file URLs are not returned.
get_order_status
ChatGPTRead a Paperkin printed-book order's status using its actual order number. Cannot identify the last payment, charge cards, cancel orders or issue refunds. For refund requests or a missing order number, give the customer https://print-factory-eta.vercel.app/support and founders@loralabs.co; staff identify and review the purchase. Do not claim a refund or substitute generic Stripe Dashboard instructions.
get_prices_and_delivery
ChatGPTRead prices, formats, shipping countries and delivery estimates for physical printed books. Website checkout supports 1–30 copies per order and requires the user's payment approval; this tool cannot charge a saved card or place orders. For larger quantities contact https://print-factory-eta.vercel.app/support (founders@loralabs.co). Paperkin has no digital download or subscription storefront.
list_coloring_themes
ChatGPTUse this when the user asks what coloring book themes exist, or you need to see which drawings a theme contains before choosing one. Returns each theme's id, example drawings and the age range it suits.
plan_book_design
ChatGPTStart here for a creative book brief, adding chat-generated illustrations, or making an existing book more beautiful. Loads Paperkin's reusable design skill and actual physical formats/page minimums before generation or layout. Include book_id for exact saved source and reusable image keys. Read-only: creates no book, image, payment or order. For image prompting/editing use focus artwork; for bespoke layouts use focus composition. Then use the host's native image-generation capability and Paperkin's create/revise tools.
revise_book
ChatGPTEdit individual interior pages in ANY saved book with page_edits, including standard journals, stories, coloring books, cookbooks, photo books and custom books. Read get_book_design with page_numbers first. Page numbers are 1-based actual preview interior numbers. Author measured blocks in trim-relative points, with 36pt text margins. mode overlay preserves existing content and adds blocks; mode replace authors the complete page. Text, image, rect, rule and writingArea blocks are supported; preserve requested writing space and all words when replacing. This saves a real printable revision, preserves every unrequested page/cover and keeps prior page edits; never stop at a mockup or ask again after the user requested the edit. Reuse existing image keys or supply images paired with NEW image_keys for local art. Physical color capability stays fixed. Standard book metadata also supports: cover or interior artwork, style, title, subtitle, dedication or journal prompts. Read get_book_design first. Reuses exact saved recipes/chapters and unrequested images; creates a separate preview and retains revision lineage. Pass only changed fields. recipe_images with recipe_image_indices and chapter_images with illustration_chapters replace or add images to distinct 1-based subjects. Use actual standalone generated artwork, not a book mockup or page collage. For custom covers or changing the complete sequence use revise_custom_book. Templates are starting points: all interior layouts can be redesigned through page_edits.
revise_custom_book
ChatGPTCreates an immutable new custom-book preview, reusing saved image bytes. Replace selected interior pages by their stable ID: untouched pages and their order stay identical. Supply front/back only to change those covers. Use a complete design instead when adding/removing/reordering pages; never combine it with page patches. A metadata title change does not rewrite cover text: supply the updated front page too. For replacing art used on one page only, give it a NEW image key and change that page; reusing an existing image key changes every placement of that asset. Preserve all words and artwork unless the user's feedback asks to change them. Original preview and orders stay intact. The original print package is retained: a B&W book cannot gain colored interiors through a page revision; explain that and offer a separate color-package book if required.
revise_picture_book
ChatGPTUse this when the user wants to change a picture book: reorder, add, remove or replace pages, redo a page sheet, recrop a page, or change the cover, title, back text or colors. Read get_book_design for saved keys. pages is the complete new order: saved_key keeps a page, image_index adds a new image, or with grid a panel of a new page sheet; omit pages to keep them. The original stays. New pages follow the same rules: flat finished artwork, not a mockup of a book, page, screen or desk, no page curl, shadow, border or page numbers, every letter 15% inside the page, every word checked.
