Made with Ecrivain

The Écrivain Prépa collection

Nineteen exam-preparation books for Haiti's national exams — seven for the 9e Année Fondamentale, twelve for the Bac (NS4), in French and Kreyòl. Each was assembled, edited, laid out and exported in Ecrivain: the cover on page one, a title page, a copyright page, a table of contents, parts and chapters, and a page about the series.

The studio

Everything a book goes through, in one place

Six stages, one manuscript. Each part saves, versions and exports the same text — there is no copy-and-paste between tools.

Write

A calm editor with the binder beside it.

  • Parts, chapters and sections you reorder by drag or by touch
  • Tables, images, footnotes, equations, charts and cross-references
  • Autosave with full version history and one-click restore
  • Word goals with progress rings, daily goal and streak
  • Typewriter scrolling and distraction-free mode

Review

Nine editorial agents, and you decide.

  • Developmental, line, copy, fact-checking, consistency, subject-matter and accessibility — plus master's and doctoral examiners for theses
  • Findings quote your sentence; review them one at a time, with undo
  • Suggest mode: tracked changes you accept or reject
  • Comments, @mentions, a review workflow and team roles

Research

Know what every claim rests on.

  • A research library where each source carries its verification standing
  • Citations in APA, Chicago, MLA, Harvard, IEEE or Vancouver, with a live bibliography
  • Drift detection when the cited sentence changes
  • Terms and names checked across the whole book at once

Design

Interior and cover, previewed as you go.

  • Trim size, margins, typeface, size and leading, running heads, drop caps
  • Cover Studio — or upload a finished cover from your designer
  • Every conventional book part, in the right order
  • Full-screen preview as a phone, an e-reader or a printed page

Publish

Files a store will take.

  • Reading PDF that opens on your cover, and a print-ready interior
  • EPUB 3, Word, Markdown and HTML
  • Exports build in the background and email you, cover included
  • ISBN & rights, editions, accessibility checks, store preparation

Grow

After the book, the readers.

  • Launch planner and marketing kit
  • Writing analytics, counted from your saved versions
  • An inbox for comments, reviews and finished exports
  • Direct sales storefront (opening with checkout)

On your phone

The whole studio in your pocket

Not a viewer — the real studio, built for a thumb. Write on the bus, review a chapter in a queue, check the cover before bed.

  • A tab bar that follows youWriting, review, publishing and selling each put their own tools under your thumb. Everything else is one tap away in More.
  • Formatting on the keyboardBold, headings, lists and more ride on top of the keyboard while you type, and the line you're writing stays in view.
  • One finding at a timeSwipe through the editorial review: apply a fix, dismiss it, or undo — each a single tap.
  • Install it like an appAdd Ecrivain to your home screen and it opens full screen. If the connection drops, the chapter tells you and saves the moment you're back.

Design & publishing

Every part a real book needs

Mark a chapter as a preface, a prologue or an appendix and it takes its place: front matter numbered in roman, the story in arabic, each part named in the book's language.

Part names come out right in English, French, Kreyòl, Spanish, German and Portuguese — “Avant-propos”, “Remèsiman”, “Anteportada”.

How it works

Four steps to a finished file

1

Bring your draft

Start from a blank page or import Markdown or Word. Headings become chapters; anything the importer can't carry is reported, never dropped.

2

Write and revise

Every save is a version. Run the editorial agents, review each finding, track changes, and invite co-authors or reviewers.

3

Design

Choose the trim and the type, set the cover, mark the front and back matter, and page through the book as a reader will see it.

4

Publish

Export PDF, EPUB or Word. We email you when it's ready, and prepare the files and details each store asks for.

Questions

Frequently asked

Does the AI rewrite my book?

No. Every finding is a suggestion you apply or dismiss, and an applied fix can be undone. Tracked changes from a co-author wait for your accept or reject too. Nothing changes your manuscript without your tap.

Can I really write on my phone?

Yes. The phone layout is the full studio: chapters, formatting on the keyboard, review, comments, design, cover, preview and export. Add it to your home screen and it opens like an app. Tablets get the binder beside the text.

Which AI model reviews my chapters?

In early access the agents run built-in automated checks — long sentences, unsourced figures, mixed spelling, repeated words — clearly labelled “Sample” and free of credits. Model-backed reviews, with Claude among the providers, are switching on; the app will say which one ran every review.

Which languages can my book be in?

Any. The interface is in English; books in English, French, Kreyòl, Spanish, German and Portuguese get their book parts named in that language, and the Écrivain Prépa series above was made in French and Kreyòl.

Can I get my manuscript out?

Any time, as PDF, EPUB, Word, Markdown or HTML, depending on your plan — and Markdown on every plan. It is your book.

Is my unpublished manuscript used to train anything?

No. Text is sent to a review provider only when you run a review, and only the chapter being reviewed. Fonts are self-hosted in the studio, and the installed app keeps no copy of your manuscript on the device.

What happens if a review fails?

The credits are refunded automatically and the failure is shown as a failure — never as a clean chapter.

Is it finished?

Not entirely, and the “Honest status” section above says exactly which parts are coming. Writing, review, design and export work today.
