2. Service Description
Lullaby AI is an AI-powered mobile application that generates personalized bedtime stories for children ages 2–12. The App uses:
- Google Gemini API to generate unique, age-appropriate story text based on the child's name, age, theme, mood, and selected language.
- OpenAI TTS to narrate stories aloud with a calming preset voice.
- Lemonfox (Premium only) to clone a parent's voice for personalized narration.
Stories are generated in real-time and saved locally on your device using Apple's SwiftData framework. Each story is unique and created specifically for your child.
