Kotonoki is in early access — we're polishing the last details and submitting to App Store review. If you'd like a heads-up when it goes live (with early-access pricing for the first wave), email us at kotonoki@addicted.design.

Kotonoki spans JLPT N5 (high beginner) through to N1. During onboarding you choose your current level, and lessons surface vocabulary at and slightly above it. Furigana and romaji are always available, so beginners aren't blocked by kanji they haven't learned yet.

When you start a subscription, the first 7 days are free. You'll get full access to everything: lesson generation, unlimited vocabulary, smart reviews. We'll send a reminder before the trial ends. Cancel anytime in App Store settings — no charge if you cancel before the 7 days are up.

Subscriptions are managed by Apple. On your iPhone: Settings → tap your name → Subscriptions → Kotonoki → Cancel Subscription. Your access stays active until the end of the current billing period.

Same features, different billing cadence. Yearly costs about 37% less per month if you stick around. You can switch between them at any time inside App Store settings.

Yes. Free accounts can open one already-generated lesson per day. Generating new lessons (turning a fresh episode into a custom lesson) requires a subscription, since it uses AI infrastructure that has real per-request cost.

Kotonoki sources Japanese subtitles from the open-licensed community catalog at Jimaku. When subtitles aren't available for a particular episode, we fall back to a synopsis-based lesson — still useful, but the vocabulary is generated from the episode summary rather than the actual dialogue.

We store the minimum needed to run the app: your email (for sign-in), your vocabulary, your lesson progress, your subscription status. We don't sell, share, or use your data for advertising. Full details in our Privacy Policy.

Open the app, go to Profile → Delete Account, and confirm. This permanently removes your account, vocabulary, and progress within seconds. Catalog content (shared anime entries) stays available for other users. You can also email us at kotonoki@addicted.design if you'd like us to do it for you.

Kotonoki uses TMDB (The Movie Database) as the source. If a title exists on TMDB it can be added — try the original Japanese title (e.g. 葬送のフリーレン) or its English equivalent. We currently filter the catalog to anime and Japanese-origin titles. Adult content is filtered out by default.

Lessons, examples, and illustrations are AI-generated and can occasionally contain inaccuracies. Tap the menu (⋯) on any lesson to report a problem — we review reports and improve the system from real feedback. Use your own judgment: cross-check with a dictionary if something feels off.

Check Profile → Notifications inside the app: each type (daily phrase, streak, new episodes) has its own toggle. Then check iOS Settings → Kotonoki → Notifications — system permission must be on. If you've denied push at the system level, only the iOS Settings can re-enable it.

Yes. Apple's relay address forwards mail to your real Apple ID inbox. Account confirmation, subscription receipts, etc. all reach you normally. The only thing we can't do is see your real address.

Same studio (addicted), same paper-clean look, but separate apps and separate subscriptions — Reelingo is for English from TV shows, Kotonoki is for Japanese from anime. You can sign in with the same email or Apple/Google ID; we just won't share subscription state across the two products.

Apple charges shortly before the period renews. If you were charged after cancelling, the cancellation likely happened after that renewal point. Apple handles refunds — request one at reportaproblem.apple.com. If something looks wrong on our side, email us and we'll help.
