Kototap weaves spaced repetition into stories. Words and grammar are best learned in context, inside sentences doing real work, so that's where your reviews live. Tap a word you don't know, and it comes back in your next stories — until it sticks. Tap a word to add it to your deck • Instant, in-context explanations as you read • Every word you look up joins your deck automatically Words resurface until they stick • Spaced repetition schedules each word's return inside future stories • Watch words climb from Learning → Familiar → Comfortable, story by story Grammar gets the same treatment • Grammar patterns (〜てしまう, 〜そうだ, …) are tapped, tracked, and resurfaced just like vocabulary • One system for everything you're learning — no separate grammar study Stories always at your level • Short, engaging stories generated for you — tuned so you understand about 90% on sight • Twelve difficulty steps from N5 to N2; climb one step at a time • Made for the intermediate plateau — you know a lot of words, but native material still buries you Reading that stays fun • Story decisions let you choose where each story goes next • Listen along with built-in audio narration Spaced repetition, in context — the way words and grammar actually stick.

Bunchuu is a beautiful, fast, native companion app for WaniKani. Do your lessons and reviews anywhere — then go further, and meet every kanji where it lives: in real sentences. VOCABULARY IN CONTEXT Real context sentences for every vocabulary item. Furigana readings and plain-English grammar notes, one tap away. Translations stay veiled until you ask, so you can test yourself first. YOUR STUDIES, YOUR PACE Hand-pick exactly which radicals, kanji, and vocabulary to learn next. Review in batches, choose the ordering, and ask meaning and reading back to back — or far apart. Typo tolerance, your own synonyms, an automatic kana keyboard, and a leech threshold you control. WANIKANI'S SRS, SYNCED Works fully offline — lessons, reviews, and every mnemonic are cached on your device, and progress syncs when you're back online. Your progress lives in your WaniKani account, so you can switch between Bunchuu and the website at any time. Accuracy, streaks, and review history for every item. WATCH YOUR PROGRESS RISE Every level and every SRS stage, at a glance. Get notified the moment reviews are ready. A DELIGHTFUL PLACE TO STUDY A watercolor world, from the radicals to the snack breaks. Beautiful enough to make reviews feel like a treat. Full dark mode. PRIVATE BY DESIGN No Bunchuu account, no analytics, no tracking. Your study data syncs directly between your device and your WaniKani account. Bunchuu requires an active WaniKani account (wanikani.com). WaniKani's free trial covers its first three levels, so you can try both together. Bunchuu is an unofficial third-party app and is not affiliated with WaniKani or Tofugu, LLC.
