The complete writer's studio

From first draft to published book.

Organize your story, write, revise and format in one place, all the way to a print-ready PDF and an EPUB for the ebook stores.

Free trial in the store.
For Windows 10 and later. macOS and Linux in development.

Manuscript editor with the tree of parts, chapters and scenes. A character's name is highlighted in the text and a card shows their entry. — Hover over a name and the entry appears, right there in your text. The screens on this page show *The Lighthouse Clockmaker*, a sample book.

01 Organize

Your whole world, always at hand.

A story encyclopedia for characters, places, objects, organizations, lore and events. Every entry knows which scenes it appears in.

Names and nicknames highlighted automatically in your text
Free-form attributes: age, trade, motivation, secrets, whatever you need
Relationships between entries, a family tree and one encyclopedia for every book in a series
Genre templates, like dark fantasy, science fiction and mystery, with ready-made entry types and attributes

Encyclopedia showing the entry for the character Tomé Vidal: nicknames, description and attributes.

02 Plan

See the story before you write it.

Drag scenes around the board, cross plotlines with chapters and check the order of events apart from the reading order.

Ready-made structures: three acts, hero's journey, Save the Cat and seven-point
A timeline that flags flashbacks by itself
An ideas notebook and a research folder with notes, links, images and PDFs

03 Write

When it's time to write, just the text.

Your book divided into parts, chapters and scenes, each scene with a status, synopsis and point of view. When the moment comes, focus mode hides everything else.

Typographic quotes and dialogue dashes that follow the book's language
Versions of every scene, with word-by-word comparison
Comments anchored to passages of text
Find and replace across the whole book, with regular expressions

Focus mode: a dark screen with only the scene title and the text.

Goals

A book is made of days.

Set the book's length and your deadline. The app works out how much to write each day and shows whether you are on pace to get there.

Daily goal, writing streak and projected finish date
Days off respected: you choose your writing days
Timed writing sprints and a history of your pace

Goals screen with today's goal, writing streak, deadline and a chart of words per day.

04 Review

Catch what tired eyes let slip.

Analyses run on your computer and point out repetitions and writing habits, with the passage and scene for each one. Then approve scene by scene until the chapter is done.

Words to avoid, echoes, long sentences, passive voice and adverbs
Readability score and share of dialogue
AI consistency check and approval by scene and chapter

Text analysis with readability, most used words and the list of echoes found.

05 Format

Format like a pro, without leaving the app.

Live two-page preview and a print-ready PDF, with the details that separate a book from a document.

KDP and ISO trim sizes, plus the formats used by Brazilian printers
Mirrored margins, hyphenation, widow and orphan control
Title page, copyright page, automatic table of contents and image pages

The Lighthouse Clockmaker

not knowing where that cold was coming from. The next morning, nobody in the village mentioned the fog, because mentioning the fog in Anchor Village was like mentioning the sea.

Bento Sarmento opened the quay at six, as he had every day for the last thirty years. He counted the boats, counted what each boat owed and walked up the lower street with water still around his ankles.

From the church door, he looked up at the lighthouse. The lantern was lit in broad daylight, and that he had never seen.

“The old man has lost his mind,” he said to no one.

But he stayed there longer than he meant to, hat in hand, counting the seconds between one sweep of the light and the next. He counted twice. The result did not change, and he walked away unsure whether he wanted to know what it meant.

At the Guild, the register was still locked away. He felt for the key in his pocket, the way one checks on an aching tooth, and went on to the quay.

Chapter 1The stopped clock* * *

On the night the clock stopped, Tomé Vidal climbed the hundred and ninety steps of the lighthouse without lighting the lamp. He knew each one by its sound: the fifth creaked, the thirtieth had a splinter, the last was lower than the others.

Upstairs, the Tide Clock read 4:17. The pendulum hung straight and still, and the room smelled of cold oil. Outside, the fog was eating the village from the bottom up: first the quay, then the lower street, then the church with no bell.

He took the black notebook from his pocket and wrote down the time. Then he sat looking at what he had written. Twenty years earlier, in that same bay, the Aurora had gone down at 4:17.

The whole cover, with a spine that fits.

The spine width comes from the page count and the paper. The preview shows bleed and guides, and the back cover already saves room for the barcode.

A single image can span the whole cover

Questions

Before you install

Can I try it before buying?

Yes. Microsoft Store offers a free trial, and the app shows the days left in Settings, on the About tab.

Do I also have to pay for the AI?

AI is optional, and the app works without it. If you want to use it, you pay your chosen provider directly, with your own key. With Ollama, models run on your computer, at no cost and with no internet.

Does my text go to a server?

No. Your book is saved on your computer. The text only leaves it when you use an AI feature, and it goes straight to the provider you chose.

Can I bring in a book I've already started?

Yes. The app imports Word (.docx), Markdown and Scrivener projects, with parts, chapters, scenes and formatting. From Scrivener, characters and places become encyclopedia entries.

Which computers does it run on?

Today, PCs with Windows 10 (version 17763) or later. The purchase stays in your Microsoft account, which lets you install on up to ten Windows devices. The macOS and Linux versions are in development, with no release date yet.

Which languages is it available in?

The interface comes in Portuguese, English, Spanish, French, German and Italian, with light and dark themes. A guided tour introduces the screens the first time you open the app.

Can it handle a long book?

Yes. The app is tested with a 300,000-word book with 200 scenes. Search covers the whole book at once, and the layout preview only draws the pages on screen, so a thousand-page book scrolls without stalling.

What format is my book stored in? Will I be able to open it in 20 years?

Each book is an SQLite database on your computer, an open, documented format. The full backup (.ewproj) is a zip file with everything. And the open export creates an ordinary folder with one Markdown file per scene, plus entries, planning, comments and the research folder in Markdown and JSON, which opens in any text editor without eWriter Studio.
