AIWriteBook vs ClaudeFast

AIWriteBook is an all-in-one AI book creation platform used by 15,700+ authors to go from idea to published book in hours - not months.

Start from scratch or import an existing manuscript (.docx, .pdf, .epub). The AI learns your writing style and generates chapters that sound like you, not generic AI. Every book gets deep character development, chapter-by-chapter outlines, and a story bible that keeps your plot consistent.

Fiction authors get AI-generated characters with personalities, arcs, and motivations that drive every chapter. Non-fiction authors can upload reference materials and get structured books with citations, learning outcomes, and exercises built in.

The built-in editor lets you write, edit with AI chat (with diff view to accept/reject changes), generate illustrations, and produce audiobook narration — all without switching tools.

When you're done, generate a professional book cover, optimize your KDP keywords and blurb, and export as KDP-ready EPUB, print PDF (5x8, 5.5x8.5, 6x9 trim sizes), DOCX, or audiobook. Publish on Amazon, Apple Books, Kobo, Google Play, and Barnes & Noble directly.

Features: AI outline generation, character builder, voice-matched chapter writing, AI chat editor with diff view, image/illustration generation, cover designer, KDP keyword research, competitor analysis, audiobook generation, 25 free author tools, and support for 30+ languages.
