DouaeELGHAZAL/SawtCoop

SawtCoop is an AI-powered multimodal marketplace connecting Moroccan rural cooperatives with clients. Cooperatives photograph products and describe them in Darija (Moroccan Arabic) by voice — the app converts both into trilingual listings (FR/AR/EN) with AI-enhanced images, translations, and pricing suggestions. # SawtCoop — صوت كوب A multimodal AI platform that helps Moroccan artisans and cooperative members create professional, multilingual product listings from a photo and a voice description in Darija. ## What it does 1. The seller takes a **photo** of their product and records a **voice note in Darija** (Moroccan Arabic dialect). 2. The app sends both to Gemini 2.5, which returns a structured product listing in French, Arabic, and English. 3. Optionally, Stability AI enhances the product photo through a 5-step pipeline (background removal → SD3.5 enhancement → shadow/background → color grading → 4K upscale). 4. The listing is ready to publish to digital marketplaces and social media. ## Tech stack | Layer | Technology | |---|---| | Frontend | React 19 + Vite, CSS custom properties, RTL i18n (FR / AR / EN) | | Backend | Express.js (Node 20+) | | AI — Product analysis | Gemini 2.5 Flash Lite (multimodal: image + audio) | | AI — Darija STT fallback | HuggingFace Whisper large-v3 | | AI — Image enhancement | Stability AI SD3.5 + local Sharp pipeline | | Auth | JWT (30-day tokens), bcryptjs password hashing | ## Project structure ``` sawtcoop/ ├── backend/ │ ├── routes/auth.js # Register / login / admin endpoints │ ├── db.js # JSON-file database (users + profiles) │ ├── server.js # Express app + AI API proxy endpoints │ └── data.json # Runtime data store (git-ignored in prod) ├── src/ │ ├── contexts/ # AuthContext, CartContext, LangContext │ ├── screens/ # App screens (Capture, Marketplace, Cart, …) │ ├── services/ │ │ ├── gemini.js # Backend API calls (analyze, transcribe) │ │ ├── whisper.js # HuggingFace Whisper STT │ │ ├── imageEnhancer.js # Stability AI image pipeline │ │ └── mediaUtils.js # Shared base64 utility │ └── i18n.js # Translation strings (FR / AR / EN) └── .env.example # Required environment variables ``` ## Setup ### Prerequisites - …
