Features

Write, organise, format, preview, and export a complete book in one browser workspace.

Write and organise

Build the manuscript and its structure in one place.

Word import

Import a .docx, review detected chapters, and adjust the splits before adding it to the book.

Browser editor

Write headings, lists, quotations, code, images, scene dividers, and footnotes without installing an app.

Book structure

Arrange front matter, body matter, back matter, sections, chapters, and a generated table of contents.

Chapter history and statistics

Return to earlier chapter versions and track word, chapter, and estimated print-page counts.

Collaboration

Members can invite editors to a shared manuscript; collaborators do not need their own membership.

Cross-platform

Use the same book on macOS, Windows, Linux, Chromebooks, tablets, and phones in a modern browser.
