Less performance. More learning.

Danki gives you the detail of a reference library and the focus of a great deck. No lives, leagues, or artificial urgency—just clear feedback and useful repetition.

Read how Danki chooses kanji keywords
01

Practice the skill you actually need

Recognition and recall are scheduled separately. Vocabulary alone has four independent study directions, so reading a word never pretends to be the same as producing it.

02

Hear Japanese in context

Words, readings, grammar, and example sentences come with natural audio. Hands Free lessons turn a walk, workout, or commute into useful study time.

03

Review at the right time

Modern FSRS scheduling adapts to every card. Daily sessions resume after interruptions, and ratings always show where a card is headed next.

04

See progress without a streak trap

Daily goals, session reports, seven-day charts, and library growth timelines reveal what is changing without turning learning into a game you can lose.

05

Explore without losing your place

Search and filter the full libraries, open kanji from words and sentences, compare similar characters, bookmark vocabulary, and undo recent study actions.

06

Make the memory work yours

Use carefully reviewed Danki keywords, write private mnemonic stories, or import your own Kanji Koohii CSV entirely on-device—without sharing a login or story text.

Built to stay readable

Context when you need it. Focus when you don’t.

Reveal furigana on demand, hear the exact word or sentence, and keep the card you are learning at the center.

Why Danki exists

I wanted the missing pieces in one place.

I loved serious Japanese flashcards, but wanted audio, real sentences, better recall practice, and a way to keep learning away from a desk. Existing tools each solved part of the problem. Danki is the connected study system I wished existed—and the one I use.

Built independently, without ads, streak pressure, or dark patterns.
