🦉 Duolingo: The AI Language Coach

Have you tried Duolingo? It seems simple — but there's a super-smart AI running behind the scenes!

What Duolingo's AI does:

• Tracks which words YOU get wrong most often
• Shows those words again more frequently
• Makes lessons harder when you're doing well
• Makes them easier when you're struggling
• Predicts the BEST time to review something before you forget it

This is called adaptive learning — every student gets a personalised lesson. No two Duolingo experiences are the same! 🌍

📦 Amazon: "Customers Also Bought..."

Ever notice how Amazon shows you exactly the things you were kind of thinking about? Spooky? Nope — it's AI!

You search: "Minecraft merchandise" ↓ AI checks: What did 50,000 people buy AFTER searching for that? ↓ Shows you: Minecraft sword, creeper plush, etc. (Things YOU probably want but hadn't thought of yet!)

Amazon's recommendation AI is responsible for 35% of all their sales! 💰
