Best AI Book Writing Software

ChatGPT can generate book content, but you have to manually manage every step. We prompted for an outline, then requested each chapter separately, copy-pasting into a document. The text quality was decent, but there was no structure management, no formatting, no export, and no cover design. It took us over 2 hours of prompt engineering to produce a usable draft.

Best for: Writers who want AI assistance but are comfortable managing structure, formatting, and design themselves. Not practical for someone who wants a finished, exportable book.

Strong fiction-focused AI writing tool. Sudowrite excels at creative prose, dialogue, and narrative development. It offers chapter-level organization and "Story Engine" for generating plot-driven content. For our non-fiction test, it struggled: the output read more like creative writing than a structured guide.

Best for: Fiction authors who want AI help with creative writing specifically. If you are writing a novel, romance, or short story collection and do not need export or cover design, Sudowrite is a solid choice. For non-fiction, lead magnets, or professional content, look elsewhere. For fiction with full export capabilities, Inkfluence's AI Novel Writer covers both writing and publishing.

Jasper is a marketing copy tool that can generate long-form content, but it was not designed for books. It produced individual sections that read like blog posts rather than book chapters. No outline generation, no chapter management, no export to book formats. The Brand Voice feature is useful for maintaining tone, but book writing requires more than tone consistency.

Best for: Marketing teams generating blog posts, ads, and social media content. Not recommended for book-length projects. At $49/month, it is also the most expensive option without any book-specific features.

Designrr is an ebook formatting and design tool, not a writing tool. It lets you import existing content (blog posts, text, audio transcripts) and format it into professional-looking ebooks with templates. No AI writing capabilities. You need to bring your own text.

Best for: People who already have written content and need to format it into a polished ebook. If you need AI to write the content, pair Designrr with a writing tool, or use an all-in-one platform like Inkfluence AI's ebook generator that handles both writing and formatting.

Scrivener is the gold standard for manual book writing software. Excellent project organization, research management, and export capabilities. But it has zero AI features. You write every word yourself. The learning curve is steep, and the interface feels dated compared to modern web tools.

Best for: Experienced authors who write everything manually and need powerful project organization. If you want AI assistance, Scrivener does not help. Consider combining Scrivener's organization with AI drafting from Inkfluence AI, then importing the polished chapters.
