Best Book Writing Software in 2026
There is no single "best" book writing software — there is a best tool per job. If you need to plan, draft, revise and export a nonfiction book in one workspace, with AI chapter drafting inside it, Gixo Folio is built for that. If the manuscript is finished and only needs a polished interior, Vellum or Atticus wins, and if you want to organise a sprawling, research-heavy draft offline, Scrivener leads. Sudowrite and Novelcrafter are the specialists for AI-assisted fiction. This page compares seven tools by job, including where Gixo Folio is not the answer.
The short answer, by job
Start from what you are actually making, not from a ranking.
Plan, draft and export a nonfiction book → Gixo Folio
Folio keeps the book brief, chapter plan, drafts, Story Bible, consistency audit and export on one book. It drafts chapters with AI from your outline, then exports EPUB, editable DOCX and a print PDF at trims such as 5 × 8 and 6 × 9. Author is $19 a month for 10 AI chapters; Pro is $99 for 50. It does not produce PDF/X files, bleed or cover wraps. See Gixo Folio →
Organise a long, research-heavy draft → Scrivener
Scrivener owns long-form structure on the desktop: a one-time licence of around $59.99 for macOS or Windows, and a Compile step that outputs Word, PDF, EPUB and Kindle, Final Draft and LaTeX-ready files. Nothing else here matches its Compile range. It is an organiser and writer, not an AI drafting tool.
Format a finished manuscript → Vellum or Atticus
Vellum is the Mac-only formatting specialist — about $199.99 for ebooks or $249.99 with print, free to try before you buy. Atticus combines writing and formatting for about $147 one-time, runs on more platforms, and exports EPUB, PDF and DOCX. Both are built for the interior, not for drafting.
Write and format free in the browser → Reedsy Studio
Reedsy Studio's core editor costs nothing, with paid add-ons from about $4.99 a month. It exports EPUB 3 and a PDF/X-1a print file for print-on-demand — the one print standard in this comparison that Folio does not produce.
AI-assisted fiction → Sudowrite or Novelcrafter
Sudowrite (from about $10 a month) is built around fiction on its own models, with developmental and line edits on its upper plans. Novelcrafter (from about $4 a month) is a novel planner that lets you bring your own AI key from its Hobbyist plan up. Both go deeper on fiction craft than Folio does.
Seven book writing tools, compared on the jobs that decide them
Entry pricing checked against official vendor pages as of September 2026 — treat non-Gixo figures as approximate. Each cell states its own billing basis, because these vendors do not sell on a common one.

Do you need software that helps write the book, or software that makes the finished book look right?
Most "best writing software for authors" lists mix two different kinds of product. The field splits cleanly by mechanism:
- Formatters (Vellum, Atticus, and Reedsy Studio's export). They take a manuscript you already wrote and produce the interior and the ebook. Vellum and Atticus are one-time purchases; Reedsy's core is free. They do nothing to get the manuscript written.
- Organisers (Scrivener). A structured place to draft and rearrange a long book yourself, then compile it to many formats. The writing is entirely yours.
- AI fiction assistants (Sudowrite, Novelcrafter). Built around prose generation and story craft for novelists, sold monthly.
- Book workspace with AI drafting (Gixo Folio). One book object from brief to export: a chapter plan, AI-drafted chapters you revise, a whole-book consistency audit, then EPUB, DOCX and print PDF.
Each mechanism trades something away. Formatters trade drafting help for interior polish and a one-time price. Organisers trade AI for control and offline ownership. Fiction assistants trade nonfiction structure for craft depth. Folio trades print-shop output — PDF/X, bleed and cover wraps — and fiction-specific depth for keeping the whole nonfiction book in one place.
Where Gixo Folio is not the answer
A comparison you can cite has to cut both ways.
- Print files for a printer that demands PDF/X, bleed or a full cover wrap. Reedsy Studio exports a PDF/X-1a print file and Vellum Press builds paperbacks; Folio's print PDF is RGB with no bleed and no cover spread, because its export targets a clean interior rather than prepress.
- Writing offline on a one-time licence. Scrivener and Atticus both sell a one-time licence and run on your own machine; Folio is a browser workspace sold monthly, because its AI drafting and audit run on the server.
- Series fiction with a shared canon or your own choice of AI model. Novelcrafter lets you bring your own AI key and Sudowrite runs its own fiction models; Folio has no model choice and no canon shared across books, because it is built around one book at a time.
