About this app

Diaries that you used to hate writing and found boring—now, write them with the joy of your very own friendly AI best friend, 'AI Gochi'!

As you write down your daily experiences line by line in your diary, your typing and spelling skills will improve rapidly before you know it, and you will become deeply immersed in the pleasure of writing a diary every day!

---

✨ Here's what makes it fun with AI Gochi!

1. 🔥 Challenge yourself to write a diary in a row and earn badges!

Your record of consecutive diary writing increases every time you write a diary without missing a day. Earn the '🌱 Sprout' badge for 1 consecutive day, the '🪵 Consistency' badge for 3 consecutive days, and the '👑 Master' badge for 5 consecutive days—challenge yourself to become a real diary writer!

2. 🎯 Exciting Secret Word Mission of the Day!

Before you start writing, your AI friend presents a secret word mission every day. If you naturally include the mission word in your diary, you can earn a bonus score of +10 points! Your vocabulary grows as you apply the word every day. 3. 💬 Kind and Warm Feedback from Your AI Gochi Friend!

"You wrote a really great diary!" When you submit your diary, your friendly best friend, AI Gochi, sends you a reply full of praise. It even corrects spelling and spacing errors carefully and kindly, just like a friend.

4. 📊 Your Writing Skills Are Growing Rapidly!

Every time you submit a diary, a growth report shows you at a glance how fast you typed (typing speed), how many words you wrote (word count), and how accurate your spelling is. Check out your typing skills and writing expression abilities for yourself as they grow every day!

5. 💌 Warm Praise Reply Cards from Your Parents!

Parents who read your diary can send you praise cards full of encouragement via KakaoTalk. Boost your sense of accomplishment by reading your parents' warm messages of support!

💚 Parents, feel free to give this as a gift to your child! • Zero Harmful Ads: No ads are displayed in the children's app, providing a safe and clean learning environment.

• Natural Study Habits: Writing is not forced. Children naturally learn typing, spelling, and spacing on their own while enjoying the process like a game.

• A Warm Channel for Conversation: Monitor your child's thoughts and daily life, and communicate more intimately and affectionately with them through KakaoTalk praise cards.

Now, shall we write our first diary entry right now and take on today's secret word mission? Let's embark on a magical writing adventure! 🚀
