Coloring Book Engine is a standalone desktop design tool that helps creators produce commercial-quality coloring book pages and layouts with full KDP-ready export handling.
What is Coloring Book Engine?
Coloring Book Engine is a Windows desktop application that takes coloring book ideas (AI-generated or hand-drawn art) and outputs print-ready KDP files including pages, cover, and promotional videos. It processes images locally using the user’s own hardware and optional AI API keys, with all core features running on-device for privacy and control.
Key Features
- KDP-ready export — Automatically handles bleed (0.125″), margins, blank-page order, and cover spine width for 8.5×11, 8×10, 8.5×8.5, 7.5×9.25, A4, and custom trim sizes.
- Vectorized line art — Converts AI-generated sketches into clean, print-sharp vector lines. Eliminates fuzzy edges while maintaining character and style consistency across the entire book.
- BYOK AI integration — Connect your own ChatGPT or Gemini API key. AI usage is billed directly by the provider at their public rates; CBE never marks it up or charges a subscription.
- AI-free workflow — Import hand-drawn or licensed art; the tool still handles bleed, margin, cover spine, and KDP packaging without any AI processing.
- Coloring video generator — Turns finished pages into short coloring clips optimized for TikTok, Instagram, and YouTube Shorts, created directly from your book files.
- Real-world color palettes — Previews use community-style marker palettes that reflect how people actually color, not just RGB screen values.
- Series and template reuse — Save and reuse niches, themes, and page layouts to build a seasonal series without rebuilding from scratch.
Who is it for?
- Solo KDP publishers — Create a complete coloring book from idea to upload-ready files in one tool, with bleed and margin handled automatically.
- Graphic designers and artists — Import hand-drawn or licensed line art and let CBE handle KDP packaging, cover spine calculation, and file export.
- Content creators — Generate short coloring videos for social media promotion straight from finished pages, without extra video editing tools.
What can you do with it?
- AI-assisted book creation: Use your own ChatGPT or Gemini key to brainstorm niches, generate page lists, and produce consistent line art across a full coloring book project.
- KDP-ready file packaging: Export complete manuscripts with correct blank-page order, cover spine width for any page count, and validated trim size presets.
- Promo video production: Turn individual pages into looping coloring clips ready for social media, including time-lapse-style footage from the file itself.
How does it work?
The tool guides users through six focused steps: Plan (define niche, audience, page list), Sketch (generate or import line art), Coloring (apply palettes and preview), Book (compose pages with margin/bleed), Assets (export cover and interior files), and Video (render promotional clips). Steps are sequential but non-destructive — users can revisit any stage.

FAQ
Will Amazon block my book if I use AI-generated images?
Amazon’s policies on AI-generated content can change. Coloring Book Engine provides vectorized, cleaned line art, but compliance with KDP guidelines remains the user’s responsibility. The tool includes KDP-aware export to help meet technical requirements.
