DiaryTutor turns daily journaling into a natural way to learn a foreign language. Pick a language. Write a diary entry — about your morning coffee, a conversation, a feeling, anything. Your AI tutor reads it, gently corrects mistakes, suggests more natural phrasing, and explains why. The more you write, the more your tutor learns about your style. — FOUR AI TEACHERS, EACH WITH A PERSONALITY — • Yaya — warm, patient, perfect for beginners • Oliver — precise and encouraging, your structured guide • Inky — playful and creative, for expressive writers • Milo — moody but insightful, when you want a sharper edge Switch teachers anytime. Each one grows alongside you, leveling up from Lv 1 to Lv 15 as you write together — unlocking new expressions, new conversations, and four evolution stages. — EIGHT LANGUAGES TO CHOOSE FROM — English, Japanese, Korean, French, Spanish, German, Dutch, Chinese. Mix and match. Switch languages whenever you want. — BUDDIES: A LETTER-BASED PEN-PAL WORLD — Pair up with a Buddy who's also learning. Exchange letters at your own pace — no pressure, no notifications buzzing every minute. Real practice with real humans, gently moderated. — DEEP CORRECTIONS, NOT JUST GRAMMAR — Beyond fixing mistakes, your tutor highlights: • Code-switching habits (when you accidentally fall back to your native language) • Naturalness scores • Writing advice tailored to your level — PROGRESS YOU CAN SEE — Earn XP, unlock badges (Gold / Platinum / Cosmic), watch your character evolve, and look back on a growing diary archive in your target language. — EARLY ACCESS NOTE — You're using one of the first builds. We're shipping updates fast and listening closely. Tap "Send Feedback" to talk to us directly — every message is read. Privacy & safety: All diaries are private by default.
