Journzy is novel writing software for novelists who write every word, with a living story bible and AI built in. It is designed for authors working on long manuscripts—forty chapters, growing casts, changing relationships and multiple timelines—who need help remembering what the story has already established. The product compares the manuscript against a story bible of characters, places and relationships and flags contradictions as they write. It is native in Spanish and English, and the AI never writes in the manuscript.
The problem Journzy addresses is memory. As a novel grows, details multiply: eye color, the number of floors in a house, when two characters stopped speaking, whether they use tú or usted. A detail that everyone missed can survive the copyedit, reach print and be found by a reader in a review. Journzy’s premise is that this is not a talent problem but a memory problem. The software is built to catch continuity errors in the draft rather than in reader reviews, while keeping the author in control of every decision.
The story bible is the center of the product. Characters, places and relationships live in a knowledge graph that evolves with the story, and every fact carries evidence. Discoveries surface new entries with the line that proves them—such as a character or place appearing for the first time—and one click adds them to the bible. With autopilot on, existing entries fill themselves in, and every change is logged in history with an Undo. Authors can see, change and undo every change Journzy makes; autopilot is optional and the manuscript is never touched.
Continuity checks compare each scene with the bible. Every flag comes with the quote that proves it: the passage in the manuscript and the bible fact it clashes with. A note appears in the margin without pulling the writer out of the scene, and the Notes page offers actions such as Fix in text, It changed here and Keep as written. The AI always flags; the author decides. An unreliable narrator, a deliberate lie or an arc that turns can be kept as written. This evidence-first approach is the product’s focus: it does not write the novel, it checks it.
Journzy is native in Spanish and English, and the checks follow the book’s language. In Spanish it understands gender, agreement and the shift from usted to tú as an event in a relationship; in English it follows the titles, names and nicknames each character uses for another. The interface, help and examples are available in the writer’s language. The relationship map changes by chapter: lovers in chapter 3 can become estranged in chapter 12, and Journzy remembers when each relationship turned. A story-position control shows who was who at a chosen point, including romantic, familial, professional, adversarial and friendship bonds.
The writing studio places the manuscript in the middle and, on the right, what the scene needs: who narrates, what it is for and who is in it. After each scene is written, Journzy reads it and marks in the text the passage that does not fit the bible. The outline works as the novel’s table of contents, with every chapter and scene carrying point of view, plot lane, goal, status and word count, plus a mode for revising the outline. Worldbuilding provides a world core for every genre with modules and maps. Grammar and style lenses cover grammar, style, orthotypography, repetition, rhythm, cliché and voice without rewriting the text. Versions keeps every save as a revision with snapshots, compare, restore and a recovery bin, and beta readers can comment on the exact passage.
From manuscript to book, Journzy exports DOCX, EPUB and print PDF with book formatting and device previews, even on the Free plan. It includes KDP-ready checks for title and author, cover, page count and inner margin, and offers design styles such as Classic serif, Contemporary, Soft romance and Literary. Covers and illustrations connect authors with vetted illustrators and designers from brief to cover. Audiobooks are an add-on sold separately, with custom voices. These capabilities support the path from draft to a finished book without leaving the studio.
The benefits are tied to continuity and control. Writers can keep writing while the bible fills itself in, catch contradictions with quoted evidence, and keep deliberate breaks. The product is especially suited to writers halfway through a novel: they can bring a manuscript and Journzy proposes story-bible entries it finds—characters, places and relationships, each with the line that proves it—and any entry can be changed or undone. The deeper into the novel, the more memory it saves. Privacy terms state that manuscripts and the bible belong to the author, all rights are kept, and text is never used to train models without explicit, revocable opt-in.
Concrete use cases include checking whether Diego’s eyes were brown in chapter 2 and green in chapter 9; tracking when Marta and Diego stopped speaking; verifying whether the house on the hill had two floors or three; and noticing when Marta returns to usted with Diego after using tú since chapter 5. Authors can use the outline to plan point of view, goal, conflict and plot lanes for every scene, and use the relationship map to see how bonds change at a chosen story position. Export workflows support KDP-ready DOCX, EPUB and print PDF. The mobile app for iPhone and Android lets writers reread, comment, highlight, open the story bible as of their page, review notes and capture ideas, while writing the book in the web studio.
Journzy has two plans. Free is US$0 forever and includes the writing studio, story bible, worldbuilding, outline, grammar and style, versions, beta readers, export, and covers and illustrations. Author is US$19 per month or US$180 per year plus tax, and includes all the AI with no API keys, no tokens and no provider setup, under fair use. Author adds continuity checks with evidence, developmental diagnosis, Discoveries, semantic search, the AI map editor and character portraits. A full refund is available if requested within 14 days of the first payment, once per person. Audiobooks are sold separately and the price is shown before production. Other tools feed a codex to an AI so it can generate text without contradicting itself; Journzy reads what the writer writes and checks it against the story universe. The comparison table positions the product around continuity: free plan never expires, no API key needed, AI never writes the text, checks carry quotes, bible facts carry evidence, worldbuilding has modules and maps, one version can be shared with beta readers, export covers DOCX, EPUB and print PDF, and the product is native in English and Spanish.
Journzy’s primary value proposition is simple: you write, your story remembers. It is a continuity-focused writing studio for novelists who want the AI to watch, check and suggest—never to write—so contradictions are caught in the draft with evidence the author can act on.
