Show HN: ImagineIf – Collaborative storytelling where AI visualizes each segment

Solo dev here. Built a platform where people write short story segments starting with "Imagine if..." and others continue. AI generates an image for each part, stories branch based on community votes.

Stack: React Native/Expo, FastAPI, MariaDB, FLUX-dev via Replicate, Groq for text.

Curious what you think — especially about the cold start problem with collaborative platforms.
