The corridor still smelled of paint from the renovation nobody had asked for. Marta counted the doors as she passed them, an old habit from a different life. Room 314 was the last on the left.
She opened the door and saw the empty room.
Marta stayed in the doorway, counting nothing at all.

CHAPTER 7 - THE VISIT
The corridor still smelled of paint from the renovation nobody had asked for. Marta counted the doors as she passed them, an old habit from a different life. Room 314 was the last on the left, and the light under its door was moving.
She knocked twice. Nothing. The third knock opened it.

The room held its breath around her - the made bed, the curtains, the glass of water still sweating on the sill.

THE QUIET GARDEN
Notes on unhurried growing
Chapter One · Soil Before Seeds
The first bed you dig teaches more than any almanac ever will.
Start smaller than you think you need, and let the compost do its quiet work beneath you.
A garden forgives a late start; it never forgives hurry.
Water at the roots, early, and then leave well alone.

The questions you should be asking.
Plan on about an hour of real decisions in the guided wizard — positioning, voice, structure, outline. The writing engine then drafts your manuscript while you watch, section by section, each one written against your nine-dimension Voice DNA and audited for robotic AI phrasing before you ever read it. Most authors go from idea to a complete, edit-ready draft in a day.
Every word is yours. CoWriter takes no royalties and no rights — you can publish, sell, and adapt your book anywhere, including commercially on Amazon KDP. Works with sufficient human creative input (your idea, direction, voice, and edits) are copyrightable under current US Copyright Office guidance.
Exports are built to KDP’s print rules: PDF and DOCX with properly embedded fonts, mirrored binding-edge gutters sized to your page count, and layouts checked against KDP’s own Print Previewer. Amazon allows AI-assisted books and asks you to disclose AI-generated content — CoWriter tells you plainly what to disclose, so there’s nothing to hide and nothing to guess.
Starter is 2 books a month. Pro is 4 books plus a monthly translation, in-book images and cover sets, Premium Publishing Tools, premium formatting, and our most advanced AI writing model. Business is 12 books, 4 translations a month, and everything unlocked — and Starter can buy any of it à la carte as add-ons.
All one-time purchases: the images & covers pack is $9.99, a full book translation is $39.99, Premium Formatting is $4.99 per book, Premium Publishing Tools (Amazon SEO + A+ Content) is $10 per book, and an extra complete book is $89.99. Nothing is required — they exist so you only pay for what a specific book needs.
The publishing steps that come after your book is written: a complete Amazon listing — description, keywords, categories, and the backend search keywords most authors never fill in properly — plus designed A+ Content pages for your product page. Included with Pro and Business, or a $10 one-time unlock per book.
Yes. Import a DOCX, PDF, or EPUB up to 25MB and CoWriter reads its structure and voice, so covers, formatting, SEO, and translations all work on it like any other book. An optional $9.99 developmental rewrite — included with Business — revises the manuscript guided by your notes.
CoWriter translates your finished book into 13 languages — Spanish, German, French, Portuguese, Italian, Dutch, Polish, Swedish, Japanese, Chinese, Korean, and right-to-left Arabic and Persian. Each language edition gets its own translated cover, Amazon SEO listing, and A+ Content, exported with the correct typography and text direction.
Soon. The fiction engine — character casts and arcs, world building with rules and magic systems, a plot blueprint, and a chapter-mapped timeline — is in internal testing now, and it launches for Pro and Business subscribers. Nonfiction is what’s battle-tested and shipping today.
The price you subscribe at during beta stays your price for as long as you stay subscribed — post-beta, Starter rises from $149.99 to $199, Pro from $249.99 to $349, and Business from $599.99 to $799. And if you ever cancel, your books are archived, never deleted.
