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. However, for core tasks using your BYOK AI keys (like ideation), the heavy processing happens on your AI provider's servers. A good GPU enhances speed and enables advanced local features!

Parlo FAQ

Is there really a free trial?

Absolutely, and it's a fantastic one! You can start using Parlo completely free for your first month. There's no credit card required to sign up, so you can explore all the features of the Starter plan risk-free. Import your contacts, design beautiful emails, and send campaigns to see exactly how Parlo can transform your communication. It's the perfect way to experience the power of simple email marketing!

How does the usage-based pricing work?

Parlo's pricing is designed to be fair and flexible, growing with your business! After your free month, you choose a plan based on the number of emails you plan to send per month. The Starter plan is great for beginners, while the Business plan (the recommended option) offers more capacity and premium features like removing Parlo branding. You only pay for the emails you send, so costs scale directly with your success, not with arbitrary subscriber limits!

Can I customize the email templates to match my brand?

Yes, and we encourage it! Parlo provides a selection of beautifully crafted, mobile-responsive templates to get you started quickly. Our intuitive drag-and-drop editor then gives you full control to customize every element. Change colors, fonts, images, and layouts to perfectly align with your brand identity. Create a consistent and professional look across all your communications without any design skills needed!

How does Parlo ensure my emails are delivered?

We take deliverability seriously! Parlo uses Amazon SES, a top-tier email sending infrastructure trusted by thousands of businesses worldwide, to send all your emails. This ensures high reliability and excellent inbox placement rates. We also provide tools to monitor bounces and unsubscribes, helping you maintain a healthy sender reputation. With Parlo, you can focus on content, confident that your messages will reach their destination!
