LangJournal is an app designed to help you develop language skills by keeping a diary. It supports English, Korean, Japanese, Chinese, French, German, Spanish, Portuguese, Dutch, Italian, Polish, Swedish, and Tagalog. An AI feature instantly reviews your diary for grammar, vocabulary, and syntax.

There is also a feature for learning with friends in small teams of up to five members. You can join a team and exchange diaries and comments with people studying the same language. Keeping a foreign-language diary can be challenging on your own, but it becomes more manageable with supportive peers.

Strengthening your writing skills makes LangJournal ideal for test preparation, including TOEFL.


Feature Details:
■ Instant diary corrections powered by AI
Your English compositions and diaries (and those in other languages) are corrected by AI. Three distinct AI engines are available, each offering unique correction styles. You can receive three different sets of correction results. Writing a diary and receiving immediate feedback helps improve your language skills.


■ Chat and Conversation with AI
You can interact with the AI via text or voice, allowing you to practice language skills in a conversational format.

■ Share diaries and connect with peers in teams
Form teams of up to five members, share diaries and comments with each other, and provide mutual encouragement among users learning the same language. Group study can boost continuation rates more than threefold compared to studying alone.
※Currently, this feature is available only for learners of English, Korean, or German.

■ Pose questions to ChatGPT
You can directly ask ChatGPT questions about translations or expression improvements for practical learning support. This lets you receive instant feedback and effectively enhance your language skills.


■ Evaluate your journal entries with CEFR levels
Your diary is analyzed for vocabulary, grammar, and verb usage, then rated on a six-level CEFR scale from A1 to C2.
※Currently, this feature is available only for learners of English.

■ Attach images or videos to entries
You can attach up to four photos or videos per diary entry. Pairing images with your text makes revisiting your diary entries more enjoyable.

■ Record and verify pronunciation with voice recordings
After writing your diary, you can record your voice and save it in the app, helping you check your pronunciation. Reading aloud strengthens memory retention and aids in real-life conversations.

■ Translation
You can translate your diary entries. Verifying how naturally they read in your native language can further aid your language learning process.

■ Multiple diaries a day
You can write as many entries as you wish, and each one will be corrected by AI.


■ Passcode Lock
If you prefer privacy, lock the app with a passcode. Face ID and Touch ID are also supported.


■ Reminder Function
Research indicates that continuing for over 21 days makes it easier to maintain the habit. Studies also suggest that setting a fixed daily writing time further aids habit formation.

Writing is incredibly important for language learning—you can’t speak what you can’t write. Writing also reinforces speaking skills. Content from your diary can be used in daily conversations.
