Atticus vs Deckle: Two One-Time-Purchase Book Apps Compared (2026)
Both apps write and format a book for a single payment. Atticus runs on any device with a browser and writes offline, though its help says import and export need a connection. Deckle is a desktop app that keeps your project in a folder on your own computer. Here is what each one does, checked against each vendor's own pages in October 2026.
Atticus and Deckle are both one-time-purchase apps that take a book from draft to EPUB and print PDF. Atticus costs $147 (as of October 2026) and runs on Windows, Mac, Linux, Chromebook and any desktop or tablet browser. Atticus says it works with or without an internet connection, though its help centre (February 2024) says you need to be online to import and export files. Deckle is a desktop app for Windows, Mac and Linux that stores each project on your own computer and adds a story bible, a timeline and version snapshots.
Deckle is our app, and this is Deckle's own site, so weigh what we say about it accordingly. Every Atticus fact below comes from Atticus's own pages, read on 20 October 2026, and every Deckle fact was checked against the app's source code for version 1.7.8.

Is Atticus online only?
No. Its homepage says "Work online, offline, in a plane or on a train." Its help centre, last updated 14 February 2024, adds: "You do need to be online to import and export files". So you can write offline, but plan to be online to import a manuscript or export the book. Atticus describes itself as a Progressive Web App (PWA), "which means it works on all devices with a browser". It lists Windows, Mac, Linux and Chromebook, and "any desktop or tablet device".
Atticus also saves your words automatically and backs them up to the cloud. That gives you the same book on every device you sign in from.
Deckle also works offline. The licence check runs on your computer, and the app needs the internet only to activate, to check for updates, and to save a web page into Research when you ask it to. The difference is where the book lives, covered below, not whether you can write without Wi-Fi.
Where Atticus is ahead of Deckle
These are real advantages, and for some authors they settle the question.
Chromebook, tablets and any browser
Atticus runs on a Chromebook and in any desktop or tablet browser. Deckle has no browser version, no Chromebook build and no tablet or phone app. Both run on Linux: Atticus through its app or a browser, Deckle as a native desktop app. If you write on a Chromebook or a tablet, Atticus is the one of the two that works there.
Collaboration with editors and readers
Atticus added "Collaboration for authors, editors, and readers" on 3 December 2024. Deckle has no real-time collaboration or co-editing. In Deckle, you leave comments anchored to the text and export a DOCX, where they arrive as real Word comments for an editor to answer.
The font library
Atticus lists 1,500+ fonts and 17+ chapter themes with a custom theme builder. Deckle ships 26 presets with their own font pairings. If browsing a very large font menu matters to you, Atticus offers far more choice.
Cloud backup across devices
Atticus backs your book up to the cloud and opens it on any device you use. Deckle has no built-in cloud sync or account. Deckle keeps up to 20 zip backups on your computer (in Documents/Deckle Backups by default) and you choose the folder the project lives in, including a Dropbox or Google Drive folder.
A longer track record
Atticus's public updates log runs from 2021 to September 2026. There are more tutorials and more authors who have shipped books with it.
Where Deckle is ahead of Atticus
Research and a story bible in the same project
The Atticus homepage lists no research folder, notes system or story bible. Deckle has a Research section in its Binder that takes PDFs, images, text, Markdown and Word files, and can save a web page from a URL. Its Codex holds Characters, Locations and Items, plus sections you add yourself, and exports as a story bible in PDF or Word.
Scenes, outlining and a timeline
Atticus organises a book into chapters, volumes and parts. Deckle adds scenes and notes inside that structure. The Outliner shows a Grid View of index cards and a List view with custom columns. Continuous View reads several documents as one scroll. The Timeline shows events to scale or in "Story order", with plotlines, and flashbacks show out of sequence.
Version snapshots today
The Atticus homepage marks "Version Control" as "Coming Soon". Deckle takes a snapshot of any document and restores it from the Inspector's Versions tab.
More import and export formats
Atticus imports .docx. Deckle imports .docx, EPUB, a zipped Scrivener project and a Markdown folder. Deckle exports EPUB, PDF, DOCX (a Word version for editors and an InDesign version with named paragraph styles), Academia PDF for thesis deposit, Markdown and plain text.
The book stays in a folder you can see
A Deckle project is a folder on your computer holding a .deckle file, which is a SQLite database, plus research/images and research/files. Nothing is stored on a Deckle server. SQLite transactions are "atomic, consistent, isolated, and durable, even if the transaction is interrupted by a program crash, an operating system crash, or a power failure". The Library of Congress lists .sqlite files among the platform-independent open formats in its Recommended Formats Statement for datasets.
Atticus vs Deckle for formatting a book
Both apps produce a print-ready PDF and an EPUB from the same manuscript, and both preview the result on devices as you work.
Atticus lists 17+ chapter themes, a custom theme builder, 1,500+ fonts, full-bleed images, large print, footnotes and callout boxes. It exports EPUB, PDF and DOCX.
Deckle sets its PDFs with the Typst typesetting engine. It has 26 built-in presets, drop caps and small caps, running heads, six scene-break styles, and a footnote or endnote choice per project. It offers eight trim sizes, from 5"×8" to A4, with an optional bleed, and no custom trim size. Its special pages run from Title Page, Copyright and Dedication to Also by the Author, Book Club Questions, Glossary and Full Page Image. A Spine Width Calculator covers four paper types.
For ebooks, Deckle has four EPUB targets: Generic, Kindle, Apple Books and Kobo. The Kindle target writes an EPUB file, not a KPF file. That is the format Amazon asks for: KDP supports "books in EPUB format that meet the specifications outlined in the Kindle Publishing Guidelines." Atticus also exports EPUB and does not list MOBI or KPF.
Print specifications are the same whichever tool you use. The KDP print file requirements apply to a PDF from either app, and how an EPUB file is built explains what both apps produce underneath.
What you would lose by switching between them
No vendor publishes this, so here it is plainly.
Moving from Atticus to Deckle
You bring the text across as a DOCX exported from Atticus. Deckle splits a Word file into chapters by its heading styles. Your Atticus theme does not come across, so you pick a Deckle preset and check your front matter. You lose browser and Chromebook access, Atticus's collaboration, and its cloud copy. Deckle's demo blocks imports, so test the move with your own file only after you buy, inside the 30-day refund window.
Moving from Deckle to Atticus
Atticus imports .docx, and its help says EPUB import works "sometimes"; Pages and Google Docs files go in by saving them as .docx first. So you export a DOCX from Deckle. Atticus detects chapters from H1 or 20pt+ text, page breaks, or three empty lines, and asks you to remove any existing table of contents first. Your Codex, Timeline, Research files, snapshots and comments stay behind in Deckle, though the Codex and Timeline can each be exported to Word or PDF first. The general method for testing a move is in how to move a manuscript between writing apps.
Atticus vs Deckle price
Atticus costs $147 once, with ongoing updates and a 30-day money-back guarantee (as of October 2026). It lists no free trial.
Deckle is also a one-time purchase with every update included, and a 30-day full refund. One licence covers two computers in any mix of Windows, Mac and Linux. The current price is on the Deckle shop page. Instead of a trial period, Deckle has a free demo with no time limit, described at the end of this page.
