YourNovel.app vs Sudowrite
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.
YourNovel.app vs ChatGPT for Book Writing
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.
YourNovel.app vs NovelCrafter
NovelCrafter offers flexibility with AI model selection but requires significant manual context management through its Codex. YourNovel.app automates context entirely with Holistic Memory and offers autonomous book generation with Auto-Pilot mode — no manual context management needed.
How to Format AI-Written Books for Amazon KDP (2026 Guide)
You've written your book with AI. Now you want to publish it on Amazon KDP. This guide covers everything from manuscript formatting to legal requirements for AI-assisted content.
You've written your book with AI. Now you want to publish it on Amazon KDP. This guide covers everything from manuscript formatting to legal requirements for AI-assisted content.
Step 1: Export Your Manuscript
YourNovel.app exports directly to DOCX and PDF formats. For Amazon KDP, you'll want the DOCX format — it gives you the most control over formatting.
Step 2: Format for KDP Requirements
Amazon KDP has specific formatting requirements:
Margins: 0.25 inch minimum for eBooks, varies for print (depends on page count)
Font: Use a standard serif font (Garamond, Georgia, or Times New Roman) at 11-12pt for body text
Chapter headings: H1 formatting with page breaks before each chapter
Front matter: Title page, copyright page, dedication (optional), table of contents
Back matter: About the author, other books by the author
Step 3: AI Content Disclosure
Amazon's current policy (2026): AI-assisted content is allowed, but you must disclose AI involvement during the publishing process. Amazon does NOT require disclosure on the book itself — only in the publishing dashboard.
Key points:
- You own 100% commercial rights to content generated with YourNovel.app paid plans
- AI-assisted content is permitted across all KDP categories
- Amazon's review process checks for quality, not AI detection
- Low-quality, mass-produced AI content may be flagged or removed
Step 4: Cover Design
Your book needs a professional cover. Options:
- Canva: Free/paid templates specifically for KDP dimensions
- 99designs: Professional covers from $299
- Fiverr: Budget covers from $20-100
- AI-generated covers: Tools like Midjourney or DALL-E (check KDP policies for AI-generated images)
Step 5: Metadata Optimization
KDP metadata determines discoverability:
Title: Include your main keyword naturally
Subtitle: Use for secondary keywords
Description: 4,000 characters max — use HTML formatting for emphasis
Keywords: 7 keyword phrases per book (use long-tail keywords)
Categories: Choose 2 categories — as specific as possible
Step 6: Pricing Strategy
For eBooks:
- $2.99-9.99: 70% royalty rate
- $0.99-2.98 or $10+: 35% royalty rate
For most AI-written fiction, $3.99-4.99 is the sweet spot for new authors.
