AIWriteBook is a browser-based workspace for writing fiction and nonfiction books with AI. You train it on your previous writing so chapters follow your style, plan the book with a character builder and an editable chapter outline, and add references and citations for research-based titles. Existing drafts can be imported in .doc, .docx, .pdf, .epub, .rtf, .txt, or .md.
Inside the same workspace you edit or regenerate any paragraph, run grammar and style checks, ask a chapter AI chat assistant for direction, generate consistent illustrations and book covers, and export EPUB, PDF, or DOCX files ready for KDP and other stores, with keyword research, blurb, and category tools for the listing. It supports writing in 30+ languages and is aimed at authors, freelancers, and solopreneurs.
Every action uses credits (for example, a full chapter costs 15 credits with Gemini, 20 with Grok, or 30 with Claude). The deal has 4 tiers from $79 (500 credits per month) to $519 (5,000 credits per month). Tier 2 adds an audiobook studio and author page; Tier 3 adds book series, visual books, book translation, and BYOK through OpenRouter; Tier 4 adds NanoReads distribution.
