This is how you actually learn

Individual words with no context? Nope. "The boy eats an apple"? Nope. You learn through family drama, in Japanese.

01

Read the family chat

Messages arrive one by one, paced like real texting. The demo starts with romaji support, then shows the real kana and kanji so Japanese does not stay mysterious.

Yui
ohayō, minna! ☀️
Good morning everyone!
Obaachan Keiko
onigiri o tsukutteru yo 🍙
I'm making onigiri (Japanese rice balls)!
02

Tap any word - instant translation

Don't know a word? One tap and you get the translation right there. No dictionary, no context switch. You never have to leave the story.

Videos

Little videos from the family thread: the party, the argument, the thing someone definitely should not have posted.

Emoji battles

The picnic scene has a 10-emoji argument about whether 😌 means happy or condescending.
