The best book writing software depends on which part of the book is actually hard.
There is no single best book writing software, because "writing a book" is four different jobs. Drafting new prose, planning a story, turning material you already wrote into chapters, and formatting the finished pages are separate problems, and the tools that are excellent at one are usually mediocre at the others.
This page compares five of the tools authors ask about most — Scrivener, Atticus, Sudowrite, Google Docs and Concepts of a Book — and says plainly which job each one is built for. Concepts of a Book is one of the five, and there is an honest section below on who should not buy it.

- Drafting a book from nothing — Scrivener or Google Docs
- Planning a novel's plot and cast — Scrivener or Sudowrite
- Generating new fiction prose — Sudowrite
- Formatting a finished manuscript — Atticus
- Turning writing you already have into a book — Concepts of a Book
Book writing software compared
Pricing changes often, so this table gives each tool's pricing model rather than a figure that will be stale in a month. Check the vendor's own page for the current number. Concepts of a Book's prices are listed further down and are current.
| Tool | The job it is built for | Strongest at | Where it struggles | Pricing model |
|---|---|---|---|---|
| Scrivener | Long-form drafting and research management | Splitting a big project into scenes and folders, keeping research beside the draft, corkboard and outliner views, compiling to many formats | A genuinely steep learning curve; it organises the containers you create but will not read your existing material and propose a structure | One-time desktop licence, per platform |
| Atticus | Formatting and typesetting a finished manuscript | Producing print-ready PDF and clean EPUB from a completed draft, chapter themes, works in the browser on any operating system | It is a formatting tool. It assumes the manuscript already exists and has no view on what belongs in which chapter | One-time licence |
| Sudowrite | Generating and expanding new fiction prose | Drafting scenes, describing settings, breaking through a blank page, story and character brainstorming | Built around invented fiction. It is the wrong shape for non-fiction assembled from sermons, transcripts or journals, where the words must stay yours | Monthly or annual subscription, by credit tier |
| Google Docs | Plain writing and collaboration | Free, everywhere, excellent commenting and version history, easy to share with an editor or co-author | No book structure at all. A 90,000-word manuscript in one document becomes slow and hard to reorder, and export to print formats is poor | Free with a Google account |
| Concepts of a Book | Turning writing you already have into a structured manuscript | Reading a pile of existing source files, proposing a chapter outline you approve before paying, assembling the manuscript in your own voice, exporting DOCX | It will not invent a book you have not written. With no existing material to work from, there is nothing for it to organise | Free outline; one-time payment per book slot |
What each tool is actually like
Scrivener
Scrivener is the long-standing choice for writers who want one workspace holding the draft, the research, the notes and the images. You break the book into small documents and rearrange them on a corkboard, then compile the result into Word, PDF or EPUB at the end.
It is powerful and it is a lot to learn. Scrivener gives you the filing cabinet; deciding what goes in each drawer is still your work.
Concepts of a Book vs ScrivenerAtticus
Atticus runs in the browser and does one job very well: it takes a finished manuscript and produces a properly typeset print PDF and a clean EPUB, with chapter styling that looks professional without a designer.
It belongs at the end of the process. If your chapters are not written yet, Atticus has nothing to format.
Concepts of a Book vs AtticusSudowrite
Sudowrite is an AI writing tool aimed squarely at novelists. It expands a sketch into a scene, suggests descriptions, and helps when the page is blank and the story is still forming.
That strength is the reason it is a poor fit for non-fiction built from material you already wrote. If the point is to preserve your sermons or your interviews in your own words, generated prose works against you.
Concepts of a Book vs SudowriteGoogle Docs
Plenty of finished books were written in Google Docs. It is free, it works on every device, and nothing beats it for sending a chapter to an editor and getting comments back.
What it does not give you is book structure. Authors usually end up with one document per chapter, a folder, and a spreadsheet holding the order in their head.
How to outline a book firstWhere Concepts of a Book fits
Concepts of a Book starts from the opposite end to every other tool on this page. You upload the writing you already have — sermon archives, teaching notes, journals, podcast or interview transcripts, blog posts, essays, half-finished drafts — and it reads that material and proposes a chapter outline.
You review and edit that outline before you pay anything. Only when the structure looks right do you buy a book slot, and the manuscript is then assembled from your own words and exported as a DOCX you can hand to an editor, to Atticus, or to a formatter.
It is a good fit for pastors, coaches, speakers, memoirists, teachers and publishers sitting on years of material that never became a book.
Who should not use Concepts of a Book
We would rather you spent your money well. Choose something else if:
- You are writing a novel. This is a non-fiction organiser. It has no sense of plot, character arc or scene. Scrivener or Sudowrite will serve you far better.
- You have not written the material yet. There is nothing to assemble from an empty folder. Draft first, in whatever tool you like, then come back.
- You want the software to invent the book. It shapes and orders what you wrote; it does not manufacture expertise you have not put on the page.
- Your manuscript is finished and you only need it to look right. That is a formatting job — go straight to Atticus or a designer.
- You want live co-authoring in the document. Real-time collaborative editing is Google Docs' territory, not ours.
If none of those describe you, the outline is free, so you can see what it makes of your material before deciding.

Common questions
What is the best book writing software for beginners?
Google Docs, honestly. It is free, you already know how to use it, and the habit of writing daily matters more than the tool. Move to something structured once the material outgrows a single document.
What is the best book writing software for non-fiction?
It depends on whether the words exist yet. If you are drafting, Scrivener. If you already have years of talks, posts or notes, an assembly tool such as Concepts of a Book is doing a job the drafting apps do not attempt.
Do I need more than one of these?
Most authors do, and that is normal. A common path is to draft or assemble in one tool, edit in Word or Google Docs, and format in Atticus. They are stages, not rivals.
Can any of these publish the book for me?
No. Every tool here stops at a finished file. Publishing, distribution and marketing are separate decisions you make afterwards.
