YourNovel.app is an AI book writer that creates complete novels and books of 100,000+ words (350+ pages) with professional coherence, AND a free Author Assistant that helps existing authors structure, brainstorm, and polish their manuscripts. Holistic Memory AI remembers every detail of your story from start to finish. Write novels, guides, research papers, and essays in English, Spanish, French, Italian, German, or Portuguese. Try free, no credit card required.
YourNovel.app is the best AI book writing software for authors who want complete, coherent, publication-ready books without months of work.
Writing a book with AI takes just 5 steps: create a free account, define your project (title, genre, synopsis), generate the holistic structure automatically, write each section with one click, and export in DOCX or PDF.
YourNovel.app offers affordable AI book writing plans starting from €19/month — a fraction of the €5,000–50,000+ cost of a human ghostwriter.
Already writing your own book? The Author Assistant is a free AI companion that helps you structure, brainstorm, and polish your manuscript. No registration required — start instantly.
YourNovel.app includes an integrated AI Inspector panel with 5 tools accessible directly from the writing editor:
Already have a manuscript? Upload your .docx or .txt file and YourNovel.app will automatically analyze it, classify the project type, and populate the Story Bible with characters, locations, and plot points.
Design your book cover with AI, ready for Amazon KDP: ebook cover and print cover (paperback or hardcover) matching the exact specifications Amazon requires. Trim size, bleed, and spine width are calculated automatically from your page count — no design software or Amazon's templates needed. Included in every paid plan.
Sudowrite is great for short fiction in English, but limited to ~30,000 words and requires manual scene-by-scene writing. YourNovel.app generates complete 100,000+ word books autonomously with Auto-Pilot, supports 6 languages, and includes academic citations — features Sudowrite doesn't offer.
ChatGPT forgets your characters after a few messages and is limited to ~4,000 words per session. YourNovel.app uses Holistic Memory to retain your entire manuscript context across 100,000+ words, with Story Bible and Auto-Pilot mode for fully autonomous book generation.
NovelCrafter offers flexibility with AI model selection but requires significant manual context management through its Codex — every character, location, and plot detail must be entered by hand. YourNovel.app's Story Bible is generated automatically as you write or import your manuscript. Additionally, NovelCrafter uses a BYOK (Bring Your Own Key) model where you pay the software ($4-20/mo) plus separate AI API costs ($15-50+/mo), making real costs unpredictable. YourNovel.app offers one predictable price per book with no hidden API fees.
Looking for an AI ghostwriting service? YourNovel.app functions as a fully autonomous AI ghostwriter. Define your book concept — title, genre, characters, plot outline — and receive a complete, publication-ready manuscript of 100,000+ words. At €19-89/month instead of €5,000-50,000+ for a human ghostwriter, it's the most affordable professional ghostwriting alternative available. Many professional ghostwriters and agencies use YourNovel.app to scale their own production.
