SousChefAI - Project Summary

📱 Project Overview

SousChefAI is a production-ready iOS application that leverages multimodal AI to transform cooking. Users can scan their fridge to detect ingredients, receive personalized recipe suggestions, and get real-time cooking guidance through computer vision.

🎯 Key Features

1. AI-Powered Ingredient Scanner

• Real-time video inference using Overshoot API
• Confidence scoring for each detected item
• Manual entry fallback
• Low-confidence item highlighting

2. Intelligent Recipe Generation

• Google Gemini 2.0 for complex reasoning
• "The Scavenger" mode: uses only available ingredients
• "The Upgrader" mode: requires 1-2 additional items
• Recipe scaling based on limiting ingredients
• Match score prioritization (0.0-1.0)

3. Live Cooking Assistant

• Step-by-step guidance with progress tracking
• Real-time visual monitoring of cooking progress
• Text-to-speech announcements for hands-free operation
• AI feedback when steps are complete
• Haptic feedback for completion events

4. User Profiles & Preferences

• Dietary restrictions (Vegan, Keto, Gluten-Free, etc.)
• Nutrition goals
• Pantry staples management
• Firebase cloud sync (optional)

🏗️ Architecture

Design Pattern

MVVM (Model-View-ViewModel) + Repository Pattern

┌─────────────┐
│    Views    │ (SwiftUI)
└─────┬───────┘
      │
┌─────▼───────┐
│ ViewModels  │ (@MainActor, ObservableObject)
└─────┬───────┘
      │
┌─────▼───────┐
│  Services   │ (Protocol-based)
└─────┬───────┘
      │
┌─────▼───────┐
│ APIs/Cloud  │ (Overshoot, Gemini, Firebase)
└─────────────┘

Protocol-Oriented Design

Vision Service:

protocol VisionService: Sendable {
    func detectIngredients(from: AsyncStream<CVPixelBuffer>) async throws -> [Ingredient]
    func analyzeCookingProgress(from: AsyncStream<CVPixelBuffer>, for: String) async throws -> CookingProgress
}

Recipe Service:

protocol RecipeService: Sendable {
    func generateRecipes(inventory: [Ingredient], profile: UserProfile) async throws -> [Recipe]
    func scaleRecipe(_: Recipe, for: Ingredient, quantity: String) async throws -> Recipe
}

This design allows easy swapping of AI providers (e.g., OpenAI, Anthropic, etc.) without changing business logic.
