Frequently asked questions

Can I maintain a consistent art style across all 12 pages?

Yes. Use the same prompt style and character descriptions for every illustration. GPT Image 1.5 handles style consistency well. Tip: include 'in the style of [description]' in every prompt to keep the look unified.

Is this good enough for print publishing?

GPT Image 1.5 at medium quality produces images suitable for print-on-demand services (Amazon KDP, IngramSpark). For higher resolution, use the high quality setting at $0.07/image — still far cheaper than commissioning illustrations.

How does the audiobook version work?

Enter your story text, choose a warm narrator voice (or clone your own), and FairStack generates the narration. Add gentle background music and sound effects for a fully produced audiobook. Total runtime depends on story length — ~4 minutes for 8,000 characters.

What about longer chapter books?

Scale linearly. A 30-chapter middle-grade novel with 1 illustration per chapter + full audiobook narration costs roughly $15-20 total. See our audiobook chapter breakdown for narration-only costs.
