Now with Achievements — quiet milestones as you study. AI Sensei reads your SRS data and drills your real weak spots. Hand-crafted N5 to N1. iPhone + iPad.
Hand-crafted JLPT lessons, kana drills, verb conjugation, and an AI tutor that explains grammar mid-lesson — the way a real teacher would.
Built for serious learners. No streak guilt-trips. No cartoon owl. Just structured practice that respects your time.
Conjugaizen walks you through the JLPT levels (N5 to N1) one lesson at a time. Hand-crafted, sentence-based lessons that teach Japanese as it actually works — not a sanitised translation of English.
WHAT'S INSIDE
LESSONS (N5 to N1)
Hand-crafted, sentence-based lessons. Each one introduces a small set of words, particles, or grammar — then you build the sentences yourself, tile by tile or by typing. Lessons unlock progressively, so you always have a clear next step.
KANA DRILLS
Hiragana and katakana, row by row. Audio for every character. Unlock rows as you master them, drill in either direction.
VOCAB PRACTICE
Multiple-choice or flashcard mode. Pick your direction (JP to EN or EN to JP), pick your level. Spaced repetition keeps the right words coming back.
CONJUGATION DRILLS
Verbs and adjectives across every form — present, past, te-form, conditionals, potential, passive, causative, and the rest. Choose the families you want. Pick mode or type mode.
TRANSLATION PRACTICE
Build full sentences from prompts. Either direction, your level, your pace.
TOPICS
Want to drill every sentence that uses the te-form? Or every conditional? Topic mode pulls cycles across the entire curriculum so you can focus on one grammar point at a time.
SPACED REPETITION
Anki-style SM-2 review built in. Every word and sentence you've learnt resurfaces at the right moment. No app graveyard — your progress works for you.
LISTEN MODE
Audio-first review pass over lessons you've already learnt. Great for commutes.
CUSTOM LISTS
Pin words you want to drill more often, organised your way.

Great app, tons of lessons and stuff, although as someone who doesn’t like the use of ai much I don’t like using sensei, but I like how the app is so useful without sensei and overall a good stepping stone for people who are better with this type of format of learning, deserves 5 stars
Developer Response
Thank you so much for the kind words and the 5 stars! Really glad the app is working well for you. That's actually great to hear, because we put a lot of effort into making the core experience solid on its own. Hope it keeps serving you well on your Japanese journey!
Promo codes now unlock the discounted yearly plan right inside the app, with no store redemption screen. Settings are split into clearer sections, plus the usual fixes.
