πŸ’‘ The Insight

Learning a word feels like solving a puzzle

When you see a new word defined with words you already know, your brain works to figure it out. That cognitive effort makes the word stick.

And when the AI can't express something with your vocabulary? It uses emojis, the universal language we all understand. 🎯

Example definition for η΄― (tired):
做 很 倚 δΊ‹ δ»₯后 ηš„ ζ„Ÿθ§‰ 😴
想 睑觉 πŸ’€, 不 想 动 πŸ›‹οΈ
ε·₯作 很 倚 = 很 η΄― 😩
