Kuzushi

Kuzushi bridges the gap between textbook Japanese and actual spoken conversation. While textbooks teach formal structures, this app trains you to recognize and produce common shortenings like turning 〜てしまう into 〜ちゃった. The tool drills five distinct skills: recognizing spoken forms, shortening formal grammar, understanding meaning, choosing the correct social register, and deconstructing complex sentences. All data remains on-device with no account required.
