Inku vs Anki for Japanese
Inku gets you studying Japanese in minutes, with the decks, audio and schedule already built. Anki gives you full control, if you are willing to build and maintain the system yourself.
How does Inku compare to Anki?
The real question is not which scheduler is better. It is how much of your study time you want to spend building the study system. Anki gives you a powerful scheduler and leaves the Japanese to you: its own manual suggests starting with a shared deck and says making your own deck is the most effective way to learn a complex subject. Inku supplies the Japanese and runs the schedule, so the time you set aside goes to learning words. Inku publishes this comparison, so read it as our view; every Anki claim below links to Anki's manual or store listing.

Which should you choose?
Choose Inku if
- You want to start with kana, JLPT vocabulary, phrases and kanji that are already written, ordered and paired with audio.
- You prefer a few clear answer buttons and a review queue that is managed for you.
- You study on an iPhone or in a web browser and do not need your existing Anki collection there.
Choose Anki if
- You want to make cards from your own textbook, reading or listening, with your own fields and card templates.
- You already have an Anki collection and review history that you depend on.
- You want free desktop or Android apps, add-ons, or AnkiWeb sync between your own devices.
When is Inku the better choice?
- You do not want to choose or check a deck. Inku's decks cover JLPT N5 to N1 vocabulary, everyday topics such as food, travel and shopping and three phrase packs (casual, polite and travel), and the same app teaches hiragana, katakana and kanji. Each card shows the Japanese, its reading, the meaning and a pronunciation clip. With Anki, the quality of readings, audio and card order depends on the shared deck you pick or the cards you write.
- You want new material taught before it is tested. An Inku lesson introduces five new items, then asks you to recall the same five before they join your reviews. Anki shows new cards from a deck as part of review, so a beginner meets each word for the first time as a question.
- You want fewer scheduling decisions. Inku schedules reviews with FSRS and asks you only whether you remembered (Again or Got it), with Too easy for words you already know. Anki also supports FSRS, but you enable it in deck options and then manage desired retention, daily limits and four answer buttons yourself.
- You want kanji in the same app as your vocabulary. Inku's kanji course has 960 kanji from N5 to N1. Each one comes with meanings, readings, a memory cue where it helps and a sample word, and you learn them five at a time.
When is Anki the better choice?
- You want to make cards from your own Japanese. Anki lets you design note types with your own fields, generate several cards from one note and add audio, images and video. Inku lets you create your own cards and decks, but it does not offer templates, bulk import or sentence-mining tools.
- You already depend on an Anki collection. Inku cannot import Anki decks or review history. If years of reviews live in Anki, moving to Inku means starting a new schedule, so keep Anki for that material.
- You want detailed control over scheduling. Anki exposes deck options such as daily limits, learning steps, desired retention and a choice between FSRS and the legacy SM-2 scheduler. Inku deliberately keeps these settings out of your way.
- You want free desktop and Android study with sync. Anki is free on Windows, macOS and Linux, AnkiDroid is free on Android, and the free AnkiWeb service syncs your collection between devices. Inku has no Android app yet, and Inku's iPhone and web progress are kept separately.

The same learner in Inku and Anki
Take a learner who can read hiragana, wants to work toward JLPT N5 vocabulary, and has about fifteen minutes a day on a phone.
Setting up
In Inku: On the web, they take the introductory lesson, create an account and start Inku Pro. On iPhone, they install the app and subscribe through the App Store. Then they open Decks and choose JLPT N5.
In Anki: They install AnkiDroid or AnkiMobile, or Anki on a computer. They browse shared decks on AnkiWeb, download an N5 deck, and check that its readings and audio are what they want. They decide whether to turn on FSRS and how many new cards to allow each day.
The first session
In Inku: A lesson shows five new words with the Japanese, reading, meaning and audio, then asks them to recall the same five with Again or Got it. They can start another lesson of five if they still have time.
In Anki: Anki shows new cards from the deck in the order its author chose. The learner answers each one with Again, Hard, Good or Easy, often meeting a word for the first time as a question.
The next day
In Inku: Home shows the reviews that are due. The learner answers them, marks any word they already know as Too easy, and saves a word from class by creating their own card.
In Anki: Anki shows the cards that are due across their decks. To add a word from class, they create a note with the fields they want. If they also study on a computer, they sync through AnkiWeb.
Advice by level
Complete beginner
Start with kana before vocabulary. Inku teaches hiragana and katakana with audio and then moves into N5 words, which saves the deck-choosing step while you still cannot judge whether a deck is accurate. If you choose Anki, use one well-reviewed kana deck and one beginner vocabulary deck, not several overlapping ones.
Returning learner
If your old Anki collection still has your review history, keeping it is often simpler than starting again. If you are starting fresh, Inku lets you choose a level and mark words you already know as Too easy, so they leave your regular reviews.
Intermediate or advanced
At N3 and above, much of your new vocabulary comes from reading and listening. Anki's custom cards suit sentence mining from that material. Inku's N3, N2 and N1 decks and its kanji course give you a prepared core, but they do not replace grammar study, graded reading or listening practice.
Can you use Inku and Anki together?
You can use both, as long as each tool has a different job. A common split is Inku for the prepared core (kana, JLPT vocabulary, phrases and kanji) and Anki for sentences you collect from your own reading. Avoid studying the same beginner words in both apps, because two schedules for one word double your reviews without adding new knowledge.
Our take
Anki is the more flexible tool, and for a learner who enjoys building a study system it is hard to beat. Inku is the shorter path from deciding to learn Japanese to finishing a useful review, because the content, the order and the audio are already decided for you. Neither tool teaches grammar, and neither replaces reading and listening.
Verdict
Choose Inku if you want prepared Japanese content and a managed review schedule on iPhone or the web. Choose Anki if your own cards, an existing collection, detailed settings, or free desktop and Android apps matter more to you.
Not sure yet? Take Inku's introductory lesson in your browser. If a prepared deck feels like relief, Inku is your tool. If you catch yourself wanting to redesign the cards, you will be happier in Anki.

Common questions
Should I choose Inku or Anki for Japanese?+
Choose Inku if you want ready-made kana, vocabulary, phrase and kanji decks with audio and a managed review schedule. Choose Anki if you want to create or import your own cards, keep an existing collection, or use free desktop and Android apps.
Can I import my Anki deck into Inku?+
No. Inku does not import Anki decks or review history. You can create your own cards in Inku one at a time, but a large Anki collection is better kept in Anki.
Do Inku and Anki use the same scheduling algorithm?+
Both can use FSRS. Inku uses FSRS for every review and manages its settings for you. Anki uses the legacy SM-2 scheduler unless you enable FSRS in deck options, and then lets you adjust settings such as desired retention.
Is Inku a paid app?+
Yes. Studying in Inku needs an Inku Pro subscription, bought through the App Store on iPhone or through checkout on the web. Anki's desktop and Android apps are free, and the official iPhone app is a one-time purchase.
Does Inku work on Android or a computer?+
Inku's web app works in a browser on a computer or an Android phone. There is no Android app yet. Anki has desktop apps and the AnkiDroid app for Android.
