Lutrin
Unidus Studio
Lutrin is a workshop for writing gamebooks: each passage on an open double page, a map of every choice, dice, inventory and character sheet, then the finished book as a website, a single file or a Windows application.
Overview
Lutrin is a workshop for writing gamebooks. You don’t write chapters: you write double pages, the spread the reader sees when the book lies open.
Shape the story before the pages
• An outline in acts and scenes, story threads running through the book, a bible of characters, places and objects.
• Promises to the reader (“arriving here, they always carry the key”), checked by Lutrin against the whole book at every keystroke.
Write and connect
• A map of every choice: missing branches and dead ends show at a glance.
• Doors that open only if the reader carries an item or meets a threshold, dice rolls, fights with a bestiary.
• A character sheet you build yourself: stats, gauges, equipment, spells, notes.
• A panel that always shows what is broken and what is left to write.
• A status for each page: written, sketched, to do, abandoned.
Read and build
• “Read”: play your own book as a reader, with save slots.
• Your own illustrations, or images generated on your computer by the built-in image generator, offline (or through ComfyUI, if you have it installed).
• The finished book as a website, a single file, a Windows application or a print-ready book.
• Interface in English, French and German; your books can be written in several languages.
A sample book is included: Le Phare de Kerloc’h.
