A writing studio for character-driven fiction
The AI that catches what you missed — before your readers do.
Journzy reads your manuscript against your story bible and flags contradictions as you type. You write; the AI keeps watch over your continuity.
Private beta · invite-only · Spanish-first
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 slip. Something always slips.
Chapter two
Nobody sees it. Until a reader does.
The detail that slipped doesn't stay in the draft: it gets past the edit, it reaches print, and one ordinary night it finds you.
“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 the quiet editor at the next desk: it has read every word you've written and forgets none of them. It doesn't write your story — it keeps watch while you do.
Forty characters, three timelines, nine hundred pages: continuity is a memory problem, not a talent problem. Other tools feed your 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 world — whoever wrote the words.
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: the AI flags, you decide. Always.
Spanish-first
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
We run the AI infrastructure. You only see your manuscript and your flags.
The living bible
Your world, 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 content is not used to train models without your explicit 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.

Your story knows itself.
