My 8-year-old is learning English and loves Peppa Pig. I thought — what if he could actually pick up words from watching it? Not "tap the apple" drills, but learning from the show he already loves.

So I built YouLingua (https://youlingua.world). Paste any YouTube video and get a word-by-word interactive transcript. Click a word to save it with the exact video moment — "muddy puddles" isn't a flashcard, it's Peppa jumping in one. Saved words then power mini-games: a space shooter, hex puzzles, TikTok-style review shorts...

Browser-based, no install. Login with a Web3 wallet — no grand reason yet, just something I'm interested in. Dream is to eventually make it fully decentralized so you truly own your learning data.

Still early, but my son now asks to "play the word game." That feels like a win.
