Frequently Asked Questions
Genstory FAQ
What kind of prompt should I give the AI?
Provide a clear, descriptive prompt in natural language for the best results.

Can I customize the story after it is generated?
Yes, the creative process includes a review and customization stage. After the AI generates the initial storybook, you can read through the entire narrative and make adjustments to the text.
