# 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:**
|
|
```swift
|
|
protocol VisionService: Sendable {
|
|
func detectIngredients(from: AsyncStream<CVPixelBuffer>) async throws -> [Ingredient]
|
|
func analyzeCookingProgress(from: AsyncStream<CVPixelBuffer>, for: String) async throws -> CookingProgress
|
|
}
|
|
```
|
|
|
|
**Recipe Service:**
|
|
```swift
|
|
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.
