Hooly AI
AI Image Generation & Editing
Hooly is a mobile AI image studio built with React Native & Expo. It turns text prompts into images and packs a full AI editing toolkit — upscale, reframe, background removal, object erase, and lighting control — across four generation models (Flux 2 Pro, Flux Kontext, Nano Banana 2, and GPT Image 2). An async pipeline runs on Supabase Edge Functions that enqueue jobs to fal.ai and reconcile results via signed HMAC webhooks, with per-model cost tracking and storage quotas. The home screen is fully server-driven with A/B variant testing and user segmentation.
