Built an AI story generator for kids and worked through challenges with prompt engineering and character consistency

I have been working on this project for the past few months. I essentially vibe-coded the entire site, which allows parents to create custom stories (and storybooks complete with images and audio) for their children.

This started as a fun project to read custom stories to my niece, but I took it very seriously and it turned into sproutingstories.ai I’m really proud of what I’ve built and would love feedback from anyone, especially parents.

Some interesting technical challenges I’ve faced:

• Integrating the various customizations within the story creation
• Splicing the text story into paragraphs and pages
• Maintaining narrative coherence while incorporating personalized elements
• Balancing creativity with safety filters (a few image models threw incorrect NSFW errors)
• Generating consistent character representations across story illustrations

The prompt engineering has been really interesting. I had to build in multiple layers of analysis in the api requests while still allowing for imaginative storytelling. I’d be happy to discuss the technical approach and any models that I’ve used if anyone’s interested. The site is still a work-in-progress, but is in a very good and working state that I am proud to share. Any and all productive feedback is welcome!
