Frequently Asked Questions

Coloring Book Engine FAQ

Is Coloring Book Engine a subscription?

No, it is not a subscription! Coloring Book Engine is a desktop application you purchase with a one-time, lifetime license. The only ongoing costs are for the AI API credits you choose to use (BYOK), which you pay directly to your chosen provider like OpenAI or Anthropic, giving you full cost control!

Can I use this tool without AI?

Absolutely! Coloring Book Engine offers a fully optional AI-Free Workflow. You can bring your own hand-crafted sketches and line art, and the engine will handle everything else: preparing the book layout, generating previews, creating videos, and exporting print-ready files. AI is a powerful helper, not a requirement!

What exactly does it speed up for coloring book creators?

It accelerates the entire production and marketing process! CBE eliminates the need to switch between 5+ different programs for sketching, line refinement, page layout, color previews, and video editing. It automates technical export settings for KDP and batches tasks, turning weeks of fragmented work into a smooth, days-long workflow!

Do I need a powerful GPU?

A modern GPU is recommended for optimal performance, especially for features like local GPU colorization which runs entirely on your machine.
