## What is English Diary?

Meet your own AI English teacher — right inside your daily diary.

English Diary - AI Coach turns the simple habit of journaling into real English writing practice. Write about your day in English, tap once, and a warm AI teacher gently corrects your writing, suggests more natural phrasing, and cheers you on — free, every day, right on your device.

No account. No API key. No setup. Just open the app and start writing.

■ AI ENGLISH TEACHER COACHING
- Grammar, spelling, tense, article and preposition fixes — each with a clear explanation in your own language
- Natural, native-like expression suggestions so you sound more fluent
- A writing score (0–100) and a warm, personal note of encouragement
- All explanations appear in your app language: English, Korean, Japanese, or Chinese

■ "THIS IS WHAT I MEANT" — INTENT COACHING
Can't find the right English words? Jot down what you wanted to say in your own language. Your AI teacher compares it with your English, tells you where the meaning drifted, and shows you how a native speaker would really say it. It's like having a patient tutor who understands both what you wrote and what you meant.

■ FREE & PRIVATE
- Free AI feedback every day — no subscription, no API key, no account
- Your diary is stored only on your device, never uploaded to any server
- Only the text you choose to have corrected is sent for AI feedback (powered by Google Gemini)

■ A DIARY YOU'LL WANT TO KEEP
- Attach photos and record your mood with each entry
- Save new words and phrases to your own vocabulary notebook
- Track your writing streak, entry count, and score trends

■ PRIVATE & SECURE
- PIN lock and Face ID / Touch ID protect your diary
- Everything stays local on your device

■ BUILD A DAILY HABIT
- Reminder notifications keep your streak alive
- A visual streak counter keeps you motivated

■ FULLY MULTILINGUAL
- Complete English, Korean, Japanese and Chinese interface — the app and your teacher speak your language
