Best Book Writing Software in 2026, Compared

The best book writing software depends on which part of the book you need help with. For drafting, Google Docs is the best free choice and Scrivener ($59.99 once) is the long-standing favorite for long, complex books. For turning a finished manuscript into print and ebook files, Atticus ($147 once, any computer) and Vellum ($249.99, Mac only) lead. For AI help, Sudowrite and Novelcrafter suit fiction, and Bookbind makes a complete book from an idea.

Disclosure: we make Bookbind, one of the tools below. We have tried to judge it by the same standard as the rest and to say where something else is the better choice.

What should book writing software actually do?

Book writing software has three jobs: getting words down, keeping a long project organized, and turning the manuscript into files a printer and an ebook store will accept. No single tool is best at all three, which is why most authors use two.

• Drafting needs a distraction-free editor, reliable saving and easy sharing for feedback.
• Organizing matters once a book passes 30,000 words: moving scenes around, keeping research next to the text, tracking what each chapter covers.
• Formatting is a different skill entirely: trim sizes, margins, fonts, headers, ebook structure. Our KDP formatting guide covers what Amazon requires.

Which software is best for drafting?

Google Docs is the best free drafting tool, and Microsoft Word is the safest choice if your manuscript is going to an editor, agent or publisher.

Google Docs saves every keystroke to the cloud, keeps a full version history, works on any device and lets editors comment on the exact sentence they mean. Its weakness is length: very long documents get sluggish, so many authors keep one document per chapter.

Microsoft Word is the format the publishing industry runs on. Track Changes is the standard way editors mark up a manuscript, and agents usually ask for a .docx file. It comes with a Microsoft 365 subscription.

Which software is best for long, complex books?

Scrivener is the best tool for organizing a long book, which is why it has been a novelist's favorite for well over a decade. It splits the manuscript into scenes or sections you can drag into a new order, shows them as index cards on a corkboard, and keeps research, notes and images in the same project. When you are done, its Compile feature exports to Word, PDF, EPUB and more.

It costs $59.99 as a one-time purchase for Mac or Windows, and the free trial counts 30 days of actual use rather than 30 calendar days. The trade-off is the learning curve: Scrivener does a lot, and its export settings take an afternoon to understand.

Choose it if your book has many moving parts, such as a novel with several viewpoints, a nonfiction book built from research, or a series you want to keep consistent.

Which software writes and formats in one place?

Atticus is the best all-in-one choice: you can write in it, then format the same manuscript for print and ebook without changing tools. It exports EPUB, print-ready PDF and DOCX, previews the result on different devices, and runs on Windows, Mac, Linux and Chromebook.

It costs $147 once, including future updates, with a 30-day money-back guarantee. Its writing editor is simpler than Scrivener's, so writers with very complex projects often draft elsewhere and import into Atticus for formatting.

Which software formats a book best?

Vellum produces the most polished interiors with the least effort, but it only runs on a Mac. You import a Word file, pick a style, and Vellum lays out the print and ebook editions with professional typography.

It is free to download and try. You pay when you want to export: $199.99 for ebooks only, or $249.99 for Vellum Press, which adds print-ready PDFs.

On Windows, Atticus is the closest equivalent. Free alternatives are Reedsy Studio, a browser-based editor that exports print and ebook files, and Amazon's Kindle Create, which formats both a Kindle ebook and a paperback from a Word file. Kindle Create does not support tables, footnotes or images that run to the page edge in paperbacks, and it chooses the margins and font for you.

Which book writing software has the best AI?

For AI help drafting fiction, Sudowrite and Novelcrafter are the specialists; for a complete book, a full book generator does more of the work.

• Sudowrite keeps a Story Bible of your characters, setting and outline, and drafts scene by scene against it. Plans run from $10 to $44 a month on annual billing, with a free trial.
• Novelcrafter builds a codex of your story world and connects to the AI provider you choose with your own API key. AI starts on the $8 Hobbyist plan, and the free trial runs 21 days.
• Bookbind, which we make, plans a book from a one-sentence idea, asks about your own examples and opinions, writes it chapter by chapter with continuity tracking, and delivers an EPUB, a print-ready paperback interior, a cover wrap and an editable Word file. It is priced per book, and planning is free.

We compare these in more depth in our guide to the best AI for writing a book.

How do you choose the right writing software?

• You want free and simple: Google Docs to write, then Reedsy Studio or Kindle Create to format.
• You are writing something long and complicated: Scrivener to write, then Atticus or Vellum to format.
• You want one tool for everything: Atticus.
• You are on a Mac and want the best-looking book: write anywhere, format in Vellum.
• You want AI to help you draft fiction: Sudowrite or Novelcrafter.
• You want a finished, formatted book from an idea: Bookbind's AI book generator.

Frequently asked questions

What software do most authors use to write a book?

Most authors draft in Microsoft Word or Google Docs, because they are familiar and editors work in them. Scrivener is the most popular dedicated writing app, especially for novels and long nonfiction.

Is Scrivener worth it?

Scrivener is worth $59.99 if your book is long or complex enough that keeping track of it is a problem. For a short, simple book, Google Docs or Word does the job, and Scrivener's learning curve may not pay off.

What is the best free book writing software?

Google Docs is the best free tool for drafting. Reedsy Studio is the best free option that also formats your book, and Kindle Create formats books for Amazon at no cost.

Do I need special software to write a book?

No. Plenty of published books were written in Word or Google Docs. Dedicated software helps with organizing long manuscripts and with formatting, and formatting is where free tools tend to fall short.

What software do I need to publish on Amazon KDP?

KDP accepts a Word file or a PDF for paperbacks without bleed, and DOCX, EPUB or Kindle Create files for ebooks. Atticus, Vellum, Reedsy Studio and Kindle Create all produce files KDP accepts.

Can I write a whole book in Google Docs?

Yes. Many authors do, often with one document per chapter to keep it fast. When you are ready to publish, download it as a Word file and format it with a tool built for books.
