About Kotonoha: Japanese JLPT Vocab
ことのは Kotonoha: a Japanese learning app built around the JLPT Kotonoha (言の葉) is an original Japanese study app. It has 11,500+ JLPT vocabulary words, 465 grammar patterns, and example sentences and translations written by our own team, not generic templates. Start with hiragana and katakana, then work up to N1 vocabulary and grammar, all in one app. [HIGHLIGHTS] Why Kotonoha • Everything in English: word meanings, example translations, explanations and AI answers, plus an English voice that reads the meanings aloud in autoplay • Complete JLPT vocabulary: N5, N4, N3, N2 and N1, 11,500+ words in total • JLPT mock exams: realistic section proportions, countdown timer, automatic scoring and pass probability • Grammar pattern bank: 465 JLPT grammar patterns from N5 to N1 • Kana trainer: all 208 hiragana and katakana characters, with stroke-order animations and native audio • Voiced, semi-voiced and combination kana fully covered, with KanjiVG stroke order • FSRS spaced repetition: scheduling based on the science of memory, so you remember longer and review less • Natural-sounding TTS Japanese audio for every word and example sentence • Original examples, usage notes and mnemonic hints, so vocabulary doesn't turn into rote memorization • 10 smart quiz types: fill in the blank, synonyms, word usage, grammar fill-in-the-blank, reading passage, dialogue listening, kanji reading, kanji spelling, meaning, and listen and choose • Kana readings and pitch accent shown, so you learn the right pronunciation and accent [HIGHLIGHTS] JLPT mock exams Mock exams modeled on the real JLPT: • Choose N5, N4, N3, N2 or N1 • Full mix of grammar, reading and listening • Countdown timer, instant automatic scoring, section scores and pass probability • If your connection drops mid-exam, you can resume (your question credits aren't wasted) Dialogue listening with synced transcripts Real JLPT-style listening questions, with male and female voices in synthesized dialogues. In review you can: • Change the playback speed (0.85× / 1× / 1.25×) • Open the transcript, which highlights each sentence as it plays • Tell speakers apart by color blocks, just like a real conversation FSRS smart review Kotonoha uses FSRS (Free Spaced Repetition Scheduler), a more accurate memory model than the classic Anki algorithm. It looks at how you answer each card and works out the best time to review it. No more random cramming: each word that appears is one you're about to forget. Reminders Daily review reminders, streak-at-risk alerts and a weekly summary. Premium subscribers get personalized reminder text based on the words you missed recently, instead of a mechanical "N cards left". At most one per day, so it never gets annoying. * Premium subscription Subscribe to unlock right away: • 10 smart quiz types and JLPT mock exams • 100 advanced AI uses per day (5 on the free plan) • 5 additional Japanese voices • Personalized study reminders The price is shown in the App Store before you subscribe.
