Bookwiz works from a single sentence: you describe what your book is about, it drafts an outline, and chapters start appearing. From there you can expand a bullet, continue a section or draft a passage from a one-line note, and every suggestion is written in the voice and continuity of the chapters you have already produced. Its central differentiator is whole-manuscript memory: characters, plot points and tone stay aligned because the assistant has read everything you have written rather than starting cold each session.
The publishing side is unusually complete for a writing tool. Once you hit your word-count goal, Bookwiz exports a print-ready interior PDF with correct trim size, gutter and bleed, a reflowable EPUB and a DOCX, computes the spine width from your real page count to build a full-wrap paperback cover, and drafts the Amazon listing for you: title and subtitle options, keywords, BISAC categories and a KDP-safe description. It also recommends a Kindle price and royalty tier and drafts an About-the-Author section.
You can switch between Claude, GPT and Gemini on a per-prompt basis, and exports are available on every plan. Bookwiz never auto-publishes, because Amazon has no publish API: it prepares the files and guides your upload step by step, so your book stays on your own account. There is a free plan with no time limit and no credit card required.
