🎵 Japanese Learning App

The most fun way to learn pitch accent and break the 漢字 wall.

I love learning from songs, but pasting lyrics into three different apps just to understand one sentence killed the vibe.

So I built a simple, offline tool that does it all in one place. Paste your lyrics, see the pitch accents instantly, and finally understand Kanji without pausing the music.

夜に駆けるよるにかける
Racing into the night
君の声をきみのこえを
追いかけておいかけて

How It Works

1

Pick a song you actually like

Forget the textbook dialogues. Grab the Japanese lyrics from that track you've had on repeat for weeks.

2

Paste them in

Drop the text into the app. It instantly maps the English translation and highlights the pitch accents for you.

3

Tap what confuses you

Don't know a character? Just tap it. The app breaks the Kanji down into its parts (radicals) so you can see the logic behind the scribbles.

4

Sing along

Enjoy your music knowing what you're ACTUALLY singing about.

Why I Built This

🧩

Kanji that actually sticks

I hated rote memorization. It doesn't work. This tool breaks complex characters down into 'radicals'—the little building blocks—so you can turn strokes into a story you'll actually remember.

📈

Pitch accent you can see

Most resources ignore pitch accent, which is why so many of us struggle to sound natural. I built a visualizer that layers the pitch drops right over the lyrics, so you know exactly how to say it.

No loading screens

I wanted to study on the subway, so I made the whole thing work offline. The database lives on your phone. It's instant, snappy, and doesn't need a signal.

🎯

The "One-Screen" Flow

Stop switching between Spotify, Jisho, and Anki. I wanted to see the meaning, the reading, and the breakdown without losing my place in the song. Now you can too.
