Picture this: You're reading a fascinating article about Tokyo's latest tech trends when you encounter "経済成長" (economic growth). Instead of:

• Opening a separate dictionary app
• Typing the word manually
• Forgetting to save it for later review
• Losing your reading flow

You simply copy the word and tap one button. Within 3 seconds, you get a beautiful definition card on your screen, and that word is automatically saved to your personal learning database forever.

Sound too good to be true? I thought so too, until I built it myself last weekend.

What You'll Build Today

This isn't just another dictionary lookup tool. This is a learning acceleration system that:

✅ Captures your curiosity instantly - Zero friction between encountering a word and understanding it

✅ Builds your personal dataset - Every lookup becomes part of your learning journey

✅ Works anywhere on iOS - Safari, apps, social media, anywhere you can copy text

✅ Scales with AI - Your personal database becomes training data for future AI tutors

Why This Changes Everything

In the age of AI, your personal data is your competitive advantage. While others type "translate this Japanese word" into ChatGPT for the thousandth time, you'll have an AI that knows exactly which words you struggle with, what contexts you encounter them in, and how you learn best.

I'm using this same principle for my CFA Level 1 prep - every question I ask gets auto-saved, creating an error notebook that an AI agent reviews with me every 2 hours. Personal datasets will be the secret weapon of the AI era.
