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.

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, and 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 includes up to 2 books a month and the complete core writing workflow. Pro includes up to 4 books a month, 40 monthly images, 1 translation, Premium Publishing Tools, Premium formatting, and our most advanced AI writing model. Business includes up to 10 books a month, 100 monthly images, 3 translations, and everything in Pro. Starter can add image credit packs, translations, Premium formatting, and publishing tools when needed.
Image credit packs ($9.99 for 25 credits), full book translations ($39.99), Premium formatting ($4.99), Premium Publishing Tools ($10), and extra complete books ($89.99) are available as one-time purchases. Nothing is required. They exist so you only pay for what a specific book needs.
Every plan month, Pro includes 40 images and Business includes 100. One image covers an in-book illustration or an A+ module, and a cover version uses 1 (premium covers use 2). Monthly images reset on your billing date and do not roll over. Need more? Image credits come in packs of 25 for $9.99: they are yours forever, never expire, and are only spent after your monthly images run out.
The publishing steps that come after your book is written: a complete Amazon listing with its description, keywords, categories, and backend search keywords, plus designed A+ Content pages for your product page. Included with Pro and Business, with a one-time unlock available for Starter.
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 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 includes character casts and arcs, world building with rules and magic systems, a plot blueprint, and a chapter-mapped timeline. It is in internal testing now and 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.
