Show HN: Choose-your-own-adventure bedtime stories by AI

Hi! I have a 3-yo child that loves bedtime stories and I built an app for him that has evolved a lot during the last 5 months. The main features are: - Personalised stories with your own character names, topics (emojis) and moral - Interactive mode, which is like the "Choose your own adventure" books I used to read in the 80s - Image generation (DALL-e 3) - Text-to-speech (Google TTS) - Supports 5 languages: EN, ES, PT, FR, NO I'd love to see some feedback about the app functionality and how to find a suitable business model (that covers API expenses). Thanks in advance!
