🎯 WTSSIU - What Tech Stack Should I Use?

An intelligent tech stack recommendation system that uses information theory to find your perfect development stack in 3-4 questions

✨ What Makes This Special?

Unlike traditional decision trees that ask generic questions, WTSSIU uses Akinator-style binary search to intelligently narrow down tech stacks:

• 🧠 Smart Question Selection: Uses information theory to ask the most discriminating questions first
• ⚡ 3-4 Questions Max: Gets to your perfect stack faster than any other tool
• 🎯 50/50 Split Strategy: Each question eliminates ~50% of remaining options
• 📊 Real-time Progress: See exactly how many stacks remain after each answer
• 🔄 Dynamic Algorithm: Questions adapt based on your previous answers

🚀 How It Works

Traditional Approach vs. WTSSIU

Traditional Decision Trees	WTSSIU Smart Algorithm
Fixed question order	Dynamic question selection
6-8 questions typical	3-4 questions maximum
Generic categories first	Most discriminating questions first
Static tree traversal	Information-theoretic optimization

The Algorithm

// 1. Calculate information gain for each possible question
function calculateInformationGain(question, remainingStacks) {
  // Group stacks by their likely answers
  const groups = groupStacksByAnswer(question, remainingStacks);
  
  // Calculate entropy to find questions that split 50/50
  return entropy_before - entropy_after;
}

// 2. Always ask the question with highest information gain
const bestQuestion = questions.reduce((best, current) => 
  calculateInformationGain(current, stacks) > 
  calculateInformationGain(best, stacks) ? current : best
);

// 3. Filter remaining stacks based on answer
remainingStacks = filterStacksByAnswer(stacks, question, answer);

🎮 Example Flow

Instead of asking "Frontend, Backend, or Full-stack?" first, WTSSIU might ask:

1. "Is this primarily a frontend/UI project?" → Eliminates 50% immediately
2. "Do you prefer the JavaScript ecosystem?" → Down to 25% of stacks
3. "Working solo or with a small team?" → Down to 12% of stacks
4. "Do you need database integration?" → Final recommendation!

Result: Your perfect tech stack in 4 questions instead of 8+ 🎯

🤝 Contributing

We love contributions! Here's how you can help:

1. Add New Tech Stacks: Update tree.json with new recommendations
2. Improve Questions: Add smarter discriminating questions to smart-tree-walker.ts
3. Better Scoring: Enhance the scoringFn for existing questions
4. UI/UX: Improve the user experience and visual design

Adding a New Stack

// Add to smart-tree-walker.ts
{
  id: 'new_question',
  text: 'Your discriminating question?',
  type: 'boolean',
  options: ['Yes', 'No'],
  scoringFn: (stack) => {
    // Return 1 if stack matches this criteria, 0 if not
    return stack.tags.includes('your-criteria') ? 1 : 0;
  }
}

📈 Analytics & Insights

WTSSIU tracks (anonymously):

• Question effectiveness and information gain
• User completion rates and drop-off points
• Most popular tech stack recommendations
• Algorithm performance metrics

🏆 Why Information Theory?

Traditional decision trees follow predetermined paths. WTSSIU uses Claude Shannon's information theory to:

• Maximize Information Gain: Each question eliminates the maximum number of possibilities
• Minimize Decision Time: Reach conclusions in log₂(n) questions where n = number of stacks
• Adapt Dynamically: Questions change based on remaining possibilities
• Optimize User Experience: Reduce cognitive load and decision fatigue
