鯉躍龍門 · KOINORI

Sound Japanese,
not just read it.

Most apps teach you to recognise words. Koinori teaches you to say them, with real-time pitch-accent feedback no other app gives you. Read graded stories, mine sentences in a tap, and watch your koi leap the Dragon Gate as your Japanese matures.

The difference

Hear your own pitch

See and correct your pitch-accent in real time. Perception drills, a live contour you can match against native speakers, and scored practice on words and short phrases. The thing every other app skips.

Read real Japanese sooner

Graded, comprehensible-input stories with one-tap furigana. Always slightly above your level, never out of reach.

Remember it for good

Reviews scheduled by FSRS, the modern spaced-repetition algorithm, so you study the right card at the right moment and nothing slips.

鯉 → 龍

A pond of koi that become dragons

Each koi is a part of your Japanese: kana, kanji, listening, pitch. As a koi truly matures it leaps the Dragon Gate and becomes a dragon in your garden. Progress you earn through real competence, never points for showing up.

Help shape Koinori

We're building this for people the other apps let down. Two minutes of honesty here directly shapes what we build.

1.Which language are you here to learn first?
2.How far along are you?
3.What's your main reason for learning?
4.What are you using to learn right now?
5.Think about the last time you stopped, stalled, or got frustrated learning. What happened?
6.How much of a problem is your pronunciation - sounding natural - right now?
7.If a new app could only nail ONE of these first, which would you pick?

Pick the single one that matters most, so we learn what to build first.

8.Roughly how much do you spend on learning in a typical month?
9.Where do you go for learning tips, or expect to hear about an app like this?
