🏆 AI Sports Talent Assessment Platform

1) Clone the repository

Open PowerShell and run (one-line):

git clone https://github.com/Tarun-goswamii/AI-Powered-Sports-Assessment-Application.git ; cd "AI-Powered-Sports-Assessment-Application/src/FLUTTER KA CODEBASE/sports_assessment_app"

2) One-click installers (recommended)

To make demos and judging easy we provide three installer batch files in the project root. After cloning the repo, connect your target device (Android phone or Windows machine) and double-click the matching installer:

Install (Android).bat — Installs dependencies, prompts for RESEND_API_KEY, deploys Convex, and launches the app on a connected Android device or emulator.
Install (Windows).bat — Installs dependencies, prompts for RESEND_API_KEY, enables Windows desktop support, deploys Convex, and launches the Windows desktop build.
Install (iOS).bat — macOS helper that prints the exact iOS/macOS commands (iOS builds require macOS/Xcode). Run the printed commands on a macOS terminal.

What the batch files do:

Install Node and Flutter dependencies (npm install, flutter pub get).
Prompt for your RESEND_API_KEY and call npx convex env set to save it to the deployed Convex environment.
Deploy the Convex backend (npm run deploy).
Run flutter run for the selected target.

Notes & tips:

First run will take longer because npm and Flutter will download packages and set up build artifacts.
If npx convex env set fails because you're not logged in, run npx convex login once and then re-run the batch file.
Ensure a device is connected (Android USB debugging enabled) or that you've enabled Windows desktop prerequisites (Visual Studio and Developer Mode) before running the corresponding batch file.

3) Mobile-specific prerequisites

Android SDK (installed via Android Studio) with platform-tools
USB drivers for your device (Windows)
A physical Android device with USB debugging enabled, or an Android emulator (AVD)

4) Windows-specific prerequisites

Windows 10/11 (64-bit)
Enable Developer Mode (Settings → Update & Security → For developers)
Visual Studio with "Desktop development with C++" workload installed (required by Flutter Windows tooling)
Flutter configured for Windows desktop support

Visual Studio install checklist

If you don't already have Visual Studio installed, install Visual Studio Community (2022 or later) and select the following during installation:

Workload: "Desktop development with C++" (required)
- Component: MSVC v143 (or latest) - VS 2022 C++ x64/x86 build tools
- Component: Windows 10 SDK (10.0.19041.0 or later)
- Component: C++ CMake tools for Windows
- Optional: Windows Universal C Runtime SDK

After installing Visual Studio, run:

flutter doctor --windows

This will confirm the Windows toolchain is ready. If flutter doctor flags missing components, re-run Visual Studio Installer and add the missing items.

npm run deploy

After deploy, Convex functions will be available at https://<your-project>.convex.cloud (the repo is preconfigured to use fantastic-ibex-496.convex.cloud when deployed there).

5) Run the Flutter app on Android (physical device)

Mobile-specific prerequisites

Android SDK (installed via Android Studio) with platform-tools
USB drivers for your device (Windows)
A physical Android device with USB debugging enabled, or an Android emulator (AVD)

Steps to run on Android device

Enable USB debugging on your Android device.
Connect the device to your PC via USB.
Verify the device is detected:

flutter devices

Run the app:

flutter run

Use r for hot reload and R for full restart in the terminal.

6) Run the Flutter app on Windows (desktop)

Windows-specific prerequisites

Windows 10/11 (64-bit)
Enable Developer Mode (Settings → Update & Security → For developers)
Visual Studio with "Desktop development with C++" workload installed (required by Flutter Windows tooling)
Flutter configured for Windows desktop support

Visual Studio install checklist

If you don't already have Visual Studio installed, install Visual Studio Community (2022 or later) and select the following during installation:

Workload: "Desktop development with C++" (required)
- Component: MSVC v143 (or latest) - VS 2022 C++ x64/x86 build tools
- Component: Windows 10 SDK (10.0.19041.0 or later)
- Component: C++ CMake tools for Windows
- Optional: Windows Universal C Runtime SDK

After installing Visual Studio, run:

flutter doctor --windows

This will confirm the Windows toolchain is ready. If flutter doctor flags missing components, re-run Visual Studio Installer and add the missing items.

Enable Windows support and run:

flutter config --enable-windows-desktop
npx convex env set RESEND_API_KEY re_your_real_key_here # if not already set
flutter run -d windows

7) Helpful scripts & commands

Deploy Convex + run app together:

npm run deploy-and-run

Run Convex locally in dev mode (auto reload):

npm run dev

Seed demo data (convenience):

npm run seed-demo

8) Resend (Email) notes & Free tier limitations

If your Resend account is on the Free tier, you can only send emails to verified addresses (sandbox mode). Domain verification alone does not remove this restriction.
To send to arbitrary recipients, upgrade to Resend Transactional plan (click "Upgrade" on Resend dashboard).
For demo/testing you can add test addresses to the allowlist at https://resend.com/settings/audiences or use the temporary workaround implemented in the repo that routes emails to your verified address while preserving the intended recipient in the subject line.

9) Common troubleshooting

If Flutter build fails: run flutter doctor -v and resolve missing components.
If Convex deployment fails: ensure you're logged in (npx convex login) and RESEND_API_KEY is set.
If email requests return 403 sandbox errors: upgrade Resend or add test addresses to the allowlist.

✅ How to use this repo (end-to-end quick flow)

Open the repo in VS Code (File → Open Folder → select sports_assessment_app).
Open a PowerShell terminal in VS Code (Terminal → New Terminal).
Install dependencies:

npm install
flutter pub get

Set Convex env variable for Resend (replace with your key):

npx convex env set RESEND_API_KEY re_your_real_key_here

Deploy backend once (or when changed):

npm run deploy

Run the app (mobile or Windows):

Android physical device:

flutter run

Windows desktop:

flutter run -d windows

For backend development, run Convex dev in a separate terminal:

npm run dev

Seed demo data (optional):

npm run seed-demo

🔒 Environment & Security Notes

Never commit API keys or secrets into the repository.
For CI / production, store secrets in Convex environment variables or your hosting provider's secrets manager.
lib/core/config/app_config.dart contains a development key for convenience. Replace or remove for production use.

✅ Quick checklist — One-line commands (for judges / demo reviewers)

Run these commands in order from the project root. They are the shortest path to a working demo on a connected Android device or Windows desktop.

Clone & enter:

git clone https://github.com/Tarun-goswamii/AI-Powered-Sports-Assessment-Application.git ; cd "AI-Powered-Sports-Assessment-Application/src/FLUTTER KA CODEBASE/sports_assessment_app"

Install deps:

npm install ; flutter pub get

Set Resend key (one-time):

npx convex env set RESEND_API_KEY re_your_real_key_here

Deploy backend (one-time):

npm run deploy

Run the app on Android:

flutter run

Or run on Windows desktop:

flutter run -d windows

If you need live backend dev mode (optional):

npm run dev

That's it — the app should open on the selected device. Use r to hot reload during development.

Quick note — Run installer .bat from PowerShell (one-liners)

After you cd into the project folder you can run any installer with a single command. Examples:

.\"Install (Android).bat"
.\"Install (Windows).bat"
.\"Install (iOS).bat"  # macOS users: prints the commands to run on macOS

🎙️ VAPI AI - Intelligent Voice Coaching Platform

What is VAPI AI?

VAPI (Voice AI Platform Interface) is a cutting-edge conversational AI platform that enables natural voice interactions. It powers the voice coaching experience in our app, making fitness guidance accessible through simple conversations.

What We're Doing with VAPI:

🤖 Meet Riley - Your AI Sports Coach

Riley is our flagship AI assistant, a specialized sports coaching agent built on VAPI's platform. Riley is an expert in:

🎯 Goal Setting: Helps athletes define SMART goals and create actionable plans
🏋️ Gym Training: Provides workout routines for all fitness levels (beginner to advanced)
💪 Custom Workout Plans: Designs personalized programs based on equipment, time, and goals
🥗 Nutrition Guidance: Offers meal planning, macro calculations, and dietary advice
📊 Form & Technique: Analyzes exercise execution and provides correction tips
🔥 Motivation: Delivers encouragement, celebrates achievements, and keeps you going
📈 Assessment Interpretation: Explains what your performance metrics mean and how to improve
🏃 Sport-Specific Training: Specialized advice for different sports (running, strength, etc.)

How Athletes Interact with Riley:

In-App Voice Chat (Current Implementation):

// lib/features/ai_chat/ai_chat_screen.dart
class AIChatScreen extends StatefulWidget {
  // Voice mode with speech-to-text + VAPI + text-to-speech
  
  Future<void> _handleVoiceInteraction() async {
    // 1. User speaks into microphone
    final spokenText = await _speechToText.listen();
    
    // 2. Send to VAPI AI (Riley)
    final response = await VapiAIService.sendMessage(
      message: spokenText,
      assistantId: 'riley-sports-coach',
    );
    
    // 3. Riley responds with intelligent advice
    final coachingAdvice = response.message;
    
    // 4. Text-to-speech speaks Riley's response
    await _flutterTts.speak(coachingAdvice);
  }
}

Example Conversations:

🗣️ Goal Setting:

You: "I want to lose weight and build muscle"
Riley: "Great goals! For body recomposition, I recommend a moderate 
        calorie deficit (300-500 below maintenance) with high protein 
        (1.6-2.2g per kg bodyweight). Focus on compound lifts 3-4x/week 
        combined with 2-3 cardio sessions. Let's start with your current 
        stats to create a personalized plan..."

🗣️ Workout Guidance:

You: "What's a good beginner workout?"
Riley: "Perfect! Let's start with a full-body routine, 3x per week. 
        Day 1: Squats (3×10), Push-ups (3×8), Rows (3×10), Planks (3×30s).
        Rest days are crucial for recovery. Can you do these at home or 
        do you have gym access?"

🗣️ Form Correction:

You: "My lower back hurts during squats"
Riley: "Lower back pain during squats often indicates form issues. 
        Check these: 1) Keep core braced throughout, 2) Don't let knees 
        cave inward, 3) Ensure you're hitting proper depth, 4) Keep chest up 
        and back neutral. Try reducing weight to master form first. 
        Would you like me to explain proper squat technique?"

🗣️ Nutrition Advice:

You: "What should I eat for muscle gain?"
Riley: "For muscle building, aim for a 300-500 calorie surplus with 
        high protein. Example meal plan: Breakfast: 4 eggs, oats, banana. 
        Lunch: Chicken breast, rice, vegetables. Dinner: Salmon, sweet potato, 
        greens. Snacks: Greek yogurt, nuts, protein shakes. Track your 
        progress weekly and adjust based on results!"

🧠 OPENAI INTEGRATION THEORY & VISION

🎯 Strategic AI Implementation Roadmap

Our OpenAI integration represents the next evolution in sports technology, moving beyond simple automation to true artificial intelligence that understands, learns, and adapts to each athlete's unique journey.

🤖 GPT-4 Advanced Coaching Intelligence

Theoretical Framework: GPT-4's transformer architecture enables understanding of complex fitness concepts, cultural nuances, and personal motivations that traditional rule-based systems cannot match. By training on sports science literature, biomechanics research, and nutritional data, GPT-4 becomes a virtual sports scientist.

Implementation Strategy:

// Theoretical GPT-4 Integration Architecture
interface AISportsCoach {
  // Multi-modal understanding
  analyzeWorkoutVideo(videoUrl: string, userContext: UserProfile): WorkoutAnalysis;
  generateNutritionPlan(goals: FitnessGoals, culturalPrefs: DietaryPreferences): MealPlan;
  predictInjuryRisk(movementPatterns: BiomechanicalData[]): RiskAssessment;
  
  // Personalized coaching
  adaptTrainingProgram(progressData: PerformanceMetrics[], plateauDetection: boolean): Program;
  providePsychologicalSupport(moodData: EmotionalState, competitionAnxiety: number): MentalCoaching;
}

Scientific Basis:

Exercise Physiology Integration: GPT-4 processes research from PubMed, sports journals, and biomechanics studies
Cultural Intelligence: Understanding of Indian dietary habits, festival impacts on training, and regional sports preferences
Personalization Algorithms: Machine learning adaptation based on individual response patterns and genetic factors

🗣️ Whisper Multilingual Processing Revolution

Theoretical Foundation: India's linguistic diversity requires AI that understands not just words, but cultural context, code-switching, and regional accents. Whisper's transformer architecture, trained on 680,000 hours of multilingual audio, provides unprecedented accuracy for Indian languages.

Technical Implementation Vision:

# Theoretical Whisper Integration for Indian Sports
class MultilingualSportsCoach:
    def __init__(self):
        self.supported_languages = [
            'hi', 'bn', 'te', 'mr', 'ta', 'gu', 'kn', 'ml', 'or', 'pa',
            'as', 'mai', 'bho', 'ur', 'ne', 'si', 'sd', 'ks', 'doi', 'mni'
        ]
        self.cultural_context = IndianSportsCulture()
    
    def process_mixed_language_command(self, audio_input):
        # Handle: "यार, मेरा workout track करो please"
        # Output: Intent(action='track_workout', language_mix=['hi', 'en'], confidence=0.97)
        
    def understand_sports_terminology(self, regional_terms):
        # "डंडे बाजी" (Haryana) -> "Wrestling practice"
        # "गिल्ली डंडा" (UP) -> "Traditional sport training"

Cultural Intelligence Features:

Festival-Aware Coaching: AI adjusts workout intensity during Diwali, Eid, Christmas
Regional Sports Integration: Understanding kabaddi techniques, kho-kho strategies, traditional wrestling
Family-Centric Approach: Coaching that considers joint family dynamics and social pressures

🎨 DALL-E Creative Motivation System

Psychological Theory: Visual motivation significantly impacts athletic performance. DALL-E's ability to generate personalized, culturally relevant imagery creates emotional connections that traditional generic images cannot achieve.

Implementation Vision:

// Theoretical DALL-E Integration for Achievement Visualization
interface CreativeMotivationEngine {
  generateProgressArt(transformation: PhysicalProgress): MotivationalImage;
  createCulturalCelebration(milestone: Achievement, region: IndianState): FestivalArt;
  visualizeGoals(aspirations: FitnessGoals, personality: PersonalityType): InspirationalImage;
  
  // Examples:
  // "Generate celebration art for Rajesh from Punjab who just completed his first marathon, 
  //  incorporating Sikh cultural elements and bhangra energy"
  //
  // "Create motivational image for Priya from Kerala who lost 15kg, showing traditional 
  //  Kathakali dance poses representing her transformation journey"
}

Artistic Intelligence Applications:

Cultural Celebration: Achievement images incorporating regional festivals, traditional clothing, local landmarks
Personal Transformation Art: Before/after artistic interpretations that celebrate individual journeys
Goal Visualization: Future-state imagery showing athletes achieving their dreams in culturally relevant contexts

🌍 Societal Impact Through AI Integration

Breaking Language Barriers

Traditional fitness apps serve only English-speaking urban populations. Our OpenAI integration democratizes access:

Rural Accessibility: Farmers in Haryana can receive coaching in Haryanvi dialect
Elder Inclusion: Senior citizens can interact in their native languages without technology barriers
Educational Bridge: Children learn fitness concepts in mother tongue, then transition to English terms

Cultural Preservation Through Technology

Traditional Sports Revival: AI coaching for yoga, kalari payattu, silambam, gatka
Regional Exercise Integration: Incorporating traditional Indian exercises into modern fitness routines
Generational Knowledge Transfer: AI learns from elderly practitioners and teaches young athletes

Economic Democratization

Affordable Expertise: World-class coaching accessible to anyone with a smartphone
Language-Inclusive Business: Fitness professionals can serve clients regardless of language barriers
Digital Divide Solution: Voice interface reduces dependency on literacy and typing skills

🔬 Technical Architecture Integration

Multi-Model Orchestration

// Theoretical OpenAI + VAPI Integration Architecture
class HybridAICoach {
  async processUserInteraction(input: MultiModalInput) {
    // Stage 1: Whisper processes voice in any Indian language
    const transcription = await openai.whisper.transcribe({
      audio: input.audioBuffer,
      language: 'auto-detect',
      context: 'fitness-sports-indian'
    });
    
    // Stage 2: GPT-4 understands intent and generates response
    const coaching = await openai.gpt4.complete({
      messages: [
        {role: 'system', content: 'Expert Indian sports coach with cultural awareness'},
        {role: 'user', content: transcription.text}
      ],
      context: user.fitnessHistory + user.culturalPreferences
    });
    
    // Stage 3: VAPI converts to natural speech
    const speech = await vapi.synthesize({
      text: coaching.response,
      voice: user.preferredAccent, // 'indian-hindi', 'south-indian', etc.
      emotion: coaching.detectedMood
    });
    
    // Stage 4: DALL-E generates supporting visuals if needed
    if (coaching.needsVisualization) {
      const artwork = await openai.dalle.generate({
        prompt: coaching.visualPrompt,
        style: user.culturalAesthetics,
        context: 'motivational-fitness-indian'
      });
      return { audio: speech, visual: artwork, text: coaching.response };
    }
    
    return { audio: speech, text: coaching.response };
  }
}
