NICHIJO - One Line a Day

One line a day, in the language you're learning. NICHIJO is a daily journaling app for language learners. Write one sentence about your day — in Japanese, English, Spanish, French, Korean, or Chinese — and a thoughtful AI will gently correct your grammar, suggest more natural phrasing, translate, and surface useful vocabulary for you to remember. It's small on purpose. The hardest part of learning a language isn't grammar — it's showing up. NICHIJO is built around the idea that one honest sentence a day, written in the language you actually want to live in, beats an hour of drilling once a week. What you get - AI feedback on every entry — corrections, natural rewrites, and translations - Vocabulary cards saved automatically from your own writing - Spaced repetition review and quick quizzes to make new words stick - Six languages: Japanese, English, Spanish, French, Korean, Chinese - A calm, distraction-free writing space — no streaks, no shame, no noise Free, with subscriptions The free tier is fully usable and supported by occasional ads. Premium and Pro subscriptions unlock unlimited AI feedback, advanced vocabulary tools, and an ad-free experience. Why NICHIJO NICHIJO (日常) means "daily life" in Japanese. We believe a language isn't something you study — it's something you live in, one ordinary sentence at a time. Write your everyday. In any language.
