A writing studio for fiction novelists
You write. Your story remembers.
Journzy reads your manuscript, compares it against your story bible and catches contradictions before your readers do. The AI watches continuity; it never writes for you.

What is Journzy?
Journzy is an AI-powered writing studio for novelists. It reads your manuscript and compares it against your story bible — characters, places, relationships — flagging the continuity contradictions it finds as you write. The AI watches, checks and suggests; it never writes for you. It's built Spanish-first, and the AI comes included, no API keys.
Chapter one
You're forty chapters deep.
A cast that keeps growing, relationships that turn from chapter to chapter, three timelines and a thousand details you promised not to forget. Your story is already bigger than your memory.
Something is going to get past you. Something always does.
Chapter two
Nobody sees it. Until a reader does.
The detail everyone missed can get past the copyedit, reach print, and one ordinary night it's your reader who finds it.
“She had blue eyes in chapter 3 and brown in chapter 9. Did anyone even edit this?”
That review isn't about your talent. It's about your memory.
Chapter three
Detection, not generation
The editor that never forgets.
Journzy is your silent editor: it has read every word you've written and forgets absolutely nothing. Most importantly, it will never write your story; its job is to keep watch while you write.
Forty characters, three timelines, nine hundred pages: continuity and coherence are a problem every author runs into. Other tools feed the bible into their AI so it can write without contradicting itself. Journzy runs the other direction: it reads what you write and checks it against your narrative universe. That is the big difference. It becomes your own personal Jiminy Cricket.
Other tools help their AI stay consistent. Journzy keeps you consistent.
Every flag carries an “It's intentional” button. An unreliable narrator, a deliberate lie, an arc that turns. Journzy's AI always flags; you decide.

It speaks your language.
Journzy is built in Spanish, not translated into it. It understands grammatical gender, agreement, and something no English-first tool sees: that moving from usted to tú is an event in a relationship.
- Tú, vos and usted read as what they are: relationship signals
- Gender and agreement understood natively
- An interface in Spanish from day one — not a translation
Writing in English? That works too. But Spanish is home.
Zero setup
The AI is included.
No API keys. No token math. Just write.
Nothing to configure
Open Journzy and write. No OpenRouter keys, no model pickers, no provider dashboards.
One subscription
The AI is in the price. No second bill, no token meter to watch.
No surprises
No bill spikes, no token quota running out mid-chapter. We run the AI; you only see your manuscript and your flags.
The living bible
Your universe, alive and connected.
Characters, places and relationships in a knowledge graph that evolves with the story. Relationships change by chapter — lovers in ch. 3, estranged in ch. 12 — and Journzy remembers when each one turned.

Frequently asked
What authors ask.
Does the AI write my book?
No. It checks, suggests and remembers; you write. No code path in Journzy silently rewrites your text, and every flag carries an “It's intentional” button — you're always the authority.
Is my writing private?
Yes. Your manuscripts and your bible belong to you — you keep all rights — and your text is never used to train models without your explicit, revocable opt-in.
What if the AI is wrong about a “mistake”?
Dismiss it or mark it intentional. An unreliable narrator, a lying character or a deliberate continuity break are all legitimate: Journzy flags, you decide.
Do I need an API key?
No. The AI is included in the subscription: no keys, no tokens, no provider setup.
Can I write in English?
Yes. But Journzy is built Spanish-first, so it understands Spanish fiction better than any other tool.
I'm already halfway through a novel. Does this work for me?
Yes — that's the ideal case. Bring your manuscript and Journzy proposes the story-bible entries it finds in it: characters, places, relationships. You approve, edit or dismiss each one; nothing enters your bible without your say-so. The deeper into the novel you are, the more memory it saves you.
