Is Coloring Book Engine a subscription service?

No! Coloring Book Engine is a lifetime license purchase. You pay once and own the software forever, including free bug-fix updates. The only potential ongoing costs are for AI features, which operate on a BYOK (Bring Your Own Key) model. This means you use and pay for your own API credits directly with providers like OpenAI, so you have complete control over those costs without any mandatory monthly fee to us.

Can I use Coloring Book Engine without any AI at all?

Absolutely! CBE fully supports an AI-free workflow. You can import your own hand-drawn or digitally created line art and use the engine exclusively for its powerful production tools: arranging pages into a book, applying professional formatting for print, generating coloring videos, and exporting final assets. The AI features are entirely optional enhancements for ideation and sketching.

Do I own the content I create with Coloring Book Engine?

Yes, you retain 100% ownership of all the content you create. Whether you use your own art, generate ideas with your own AI keys, or utilize the local processing tools, the final output is your intellectual property. CBE is a tool, not a content owner. You are free to use your creations for commercial purposes, including selling the books you publish.

What are the system requirements for optimal performance?

For best performance, especially when using local GPU features for colorization, a modern system is recommended. This includes a CPU like an AMD Ryzen 5 2600 or Intel Core i5-8500, at least 16 GB of RAM, and a dedicated GPU with 4 GB of VRAM (e.g., NVIDIA GTX 1050 Ti). For the experimental local GPU colorization, a more powerful GPU with 8+ GB VRAM (like an NVIDIA RTX 3060) is suggested. The application requires about 5 GB of free disk space.
