Best Free Writing Software & Book Writing Apps (2026)

Best Free Book Writing Software for Authors

When you are writing a 70,000-word novel or memoir on a zero-dollar budget, your biggest enemy is document sprawl. You need a free book writing program that lets you jump between chapters, store character notes, and export a clean file at the end.

Reedsy Studio (Web) is the easiest starting point for self-publishing authors. You create a free account, add chapters in the left-hand sidebar, and write in a clean serif interface. When your book is finished, Reedsy exports typeset-quality EPUB and print-ready PDF files with generated front matter and a table of contents at no charge. Reedsy makes its money from its freelance editor and cover designer marketplace, so the core book editor stays free.

Wavemaker Cards (Web, Windows, Mac, Chromebook) is the closest free equivalent to Scrivener for fiction plotters. It runs in your browser as an offline-capable Progressive Web App and includes a grid planner, a Save-the-Cat-style beat board, a mind map tool, and a distraction-free manuscript editor. Just remember to click the Google Drive sync button at the end of every session.

LibreOffice Writer (Mac, Windows, Linux) is the best free Microsoft Word replacement for authors who want a traditional desktop word processor. It opens and saves standard .docx files with Track Changes intact, and its Navigator sidebar lets you jump between headings in a 300-page manuscript without lag. If you are writing a life story, compare these against our dedicated roundup of memoir writing software.

Best Distraction-Free & Markdown Writing Apps (Free)

Word processors surround your prose with rulers, ribbon toolbars, and page breaks. If you draft faster in plain text, Markdown lets you format headings, italics, and links without lifting your hands from the keyboard.

Obsidian (Mac, Windows, Linux, iOS, Android) is the best free Markdown writing app on the market. I use it daily as my personal Zettelkasten knowledge base and article outliner. Every note is a plain .md file stored in a local folder on your computer, meaning you own your work forever. You can link character profiles and research notes together with double square brackets ([[Like This]]), install the free community Longform plugin to manage book scenes, and sync across Apple devices for free using iCloud Drive. Compare it with other note tools in our best note-taking apps and best Markdown editors guides.

FocusWriter (Mac, Windows, Linux) hides your entire operating system behind a calm full-screen canvas. Move your mouse to the edge of the screen to check your daily word count ring or switch scene tabs; start typing and the menus vanish again.

Apple Notes & Apple Pages (Mac, iPad, iPhone) come pre-installed on every Apple device. If you write on a tablet with a keyboard, check our tested best writing apps for iPad before paying for an App Store subscription.

Best Free Editing & Proofreading Software

Never rely on the same brain that drafted a chapter to proofread it without help. You can build a sharp self-editing pipeline for $0 by stacking three free browser tools:

• Hemingway Editor (Free Web App): Paste a scene into Hemingway (or our free in-browser readability checker) to light up passive verbs, clusters of adverbs, and 40-word marathon sentences. Aim for Grade 6 to Grade 8 for commercial fiction and online nonfiction.
• Grammarly Free: Install the free browser extension for Google Docs and email to catch homophones, missing commas, and subject-verb slips as you type.
• ProWritingAid Free & BAWT's Free Grammar & Style Checker: ProWritingAid's free web tier lets you test its 25 fiction reports on 500-word passages, while our on-site checker scans your draft in your browser with no signup required.

When to Upgrade to Paid Author Software

Free tools will comfortably carry you through your first short stories, blog posts, and even a first novel draft. You only need to pay for software on our writing software hub when you hit one of four friction points:

1. Your manuscript structure outgrows Google Docs or Obsidian: When you are juggling 40 scenes, interview PDFs, and multiple subplots, upgrade to Scrivener ($59.99 one-time) for its Binder, Corkboard, and scene Snapshots.
2. You want effortless Apple sync and one-click blog publishing: If you write across Mac, iPad, and iPhone and publish to WordPress or Ghost, Ulysses ($39.99/year) or iA Writer ($49.99 one-time) saves hours of formatting cleanup every month.
3. You are self-editing a full-length book manuscript: Copy-pasting 500 words at a time into free checkers gets old fast. ProWritingAid Premium ($120/year or $399 Lifetime) opens your entire Scrivener or Word manuscript and flags pacing slumps, repeated echoes, and dialogue clichés across whole chapters.
4. You are building a self-publishing backlist: Once you publish two or more books, Vellum ($199.99 to $249.99 one-time on Mac) pays for itself by generating store-ready KDP print and ebook editions in under an hour.
