Everything for your book in one place

Chapters and scenes

Write in scenes, drag them into a new order, and keep track with status, point of view and scene notes.

Characters and places

Character sheets with your own fields. Atramentum notices who appears in a scene.

Corkboard

Cards with text, lists and sketches, in groups and with connections, linked to scenes and characters.

Timeline

Events in story time. Atramentum spots flashbacks when the order in your book differs from the chronology.

Character web

Relationships and states of your characters at any point in the story. Who is still alive in chapter 12?

Manuscript format, Word and e-book

Export to PDF as a standard manuscript or reading copy, to Word, e-book (EPUB, also for Kindle via KDP), Markdown or plain text, optionally with title page, dedication, imprint and your own page size. Import from Word, Scrivener, Markdown and plain text.

Revise

Style analysis with readability, long sentences, repetitions and filler words. Spelling and grammar check of the whole manuscript using your system's checker. Compare versions and have your text read aloud.

Overview

Outline as a table or scene cards, colour labels and keywords. Open a second scene or a character sheet right beside your text.

Atramentum is not notarized by Apple and not signed with a Microsoft certificate. Certificates cost money every year, and Atramentum is free. That's why macOS and Windows ask once before the first launch; the guides show how to open it anyway. iPhone and iPad are coming via the App Store.

Early testing: please make regular backups and tell me what you notice. Checksums and rescue tools are on the release page.
