Easy to use. I like the simple Japanese words that help beginner like me. Simple to use and better looking than Anki.

How a lesson works

  1. Learn a few words

    Read the Japanese and hear how each word sounds.

  2. Recall at your pace

    Know the word? Choose Got it. Flip when you want to check.

  3. Come back tomorrow

    Review the words you missed, with more time between words you know.

みず
みず

Remember it without
the answer in front of you.

Try to recall a word before checking its meaning. Choose Got it when you know it, or Again for another try. Flip whenever you want to check.

Inku uses spaced repetition to plan your next review. Words you miss come back sooner; words you remember get more time between reviews.

Answers before you start

Do I need an account to start?

No. Your first lesson runs in the browser without one: learn 15 cards, then practice recalling them. Create a free account afterward to keep learning and save your progress.

What can I learn in the web app?

Hiragana, katakana, kanji, JLPT vocabulary from N5 to N1, and everyday words and phrases. Free covers all kana, the JLPT N5 deck and the first 50 kanji. Pro opens all 24 decks and all 429 kanji.

I’m starting from zero. Is Inku for me?

Yes. Tell Inku you are a beginner during setup and start with a few simple characters and words. If you already know kana, your starting point will reflect that.

How does Inku help me remember?

Try to recall the answer, flip the card, then tap Got it or Again. Spaced repetition brings the cards you miss back sooner and leaves more time between the ones you know.

How much does Inku Pro cost?

US$7.99 a month, with no trial. Or US$49.99 a year with 7 days free for eligible new customers. Checkout shows your final price and tax. Everything you have already learned stays open for review without Pro.

Can I use Inku on my phone?

Yes. You can use the web app in your phone’s browser, or download Inku for iPhone from the App Store. The iPhone app also supports offline study.

Is Inku available on Android?

The web app works in your Android browser. The native Android app is still in development. Join the Google Play waitlist and we will email you when it launches.
