Book Writing Software
That Makes Sense
Author's Forge is free, offline book-writing software for Mac, Windows and Linux. Authors write, organize and export their books to EPUB, PDF and DOCX.
Is Author's Forge the right writing software for my book?
It depends on how you like to work. Author's Forge suits authors who want to draft, organize and export a book in one desktop app, keep their files on their own computer, and not pay for the basics: writing, organizing and exporting to EPUB, PDF or DOCX are free. It is the wrong fit if you need to co-write in real time or write on a phone, tablet or in a browser, because there is no mobile or web app. AI help is optional and uses credits from a Pro plan.

Frequently Asked Questions
Common questions about Author's Forge
Is Author's Forge really free?
Yes. The core app is free to download and use, with no account: the writing environment, manuscript organization, focus mode, themes, the book formatting editor, and export to EPUB, PDF and DOCX. AI features such as the AI assistant and AI spellcheck are optional and use credits; as of October 2026, Pro plans start at $20 a month.
Does Author's Forge work offline?
Yes. Writing, organizing and exporting all work without an internet connection, and your writing is stored on your own computer as Markdown files. Only the optional AI features need a connection. Because your library is a folder of files, you can back it up however you like, for example to an external drive.
What file formats can I export to?
EPUB, PDF and DOCX, free. EPUB export includes an automatic table of contents, your cover image and book metadata, and EPUB is the format most ebook stores accept, including Amazon KDP and Apple Books. PDF export uses print trim sizes such as 5x8 and 6x9. With a Pro plan you can also export an MP3 audiobook.
What operating systems does Author's Forge support?
macOS 12 or later, 64-bit Windows 10 or later, and 64-bit Linux (AppImage, .deb or .rpm). Download the installer for your system, run it, and start writing. There is no mobile or web version.
Is my writing data private?
Your writing is stored on your own computer, not on our servers, and we claim no rights to it. The core editor works entirely offline, so nothing you write leaves your machine. If you choose to use an AI feature, the text it needs is sent to an AI provider to process that request, as described in our privacy policy.
What is the best free writing app?
It depends on what you write and where. For drafting and publishing books on a computer, Author's Forge is a free option built for authors: unlike general document editors, it organizes libraries, series and chapters, keeps notes for world-building and characters, has a focus mode, and exports EPUB, PDF and DOCX at no cost. If you need to write on a phone or co-write in real time, a cloud document editor will suit you better.
What apps do authors use to write their books?
Many authors use general word processors, and many use dedicated book-writing software such as Author's Forge, which adds manuscript organization, chapter management, series support, notes for characters and world-building, and publishing-ready export to EPUB, PDF and DOCX.
