LangJournal helps you learn a language by keeping a diary, with AI corrections, explanations, follow-up questions, and review exercises. Write about your day in the language you're learning. AI checks grammar and unnatural expressions and helps you make your writing clearer and more natural. Each correction comes with an explanation, so you can understand why a change is needed and develop your writing skills. When you're unsure about an expression, you can ask AI directly. Ask questions about your diary, such as "Does this sound natural?", "What's the difference between 'the' and 'a'?", or "How can I say this more casually?" Keeping a diary is a way to practice writing and build a daily habit of using the language. Start with one short sentence and gradually build your grammar, vocabulary, and range of expressions. [Key Features] ■ Write a Diary With AI Corrections AI checks your diary as soon as you submit it. Get help with grammar, vocabulary, and unnatural expressions to make your writing more natural. ■ Understand Why a Correction Is Needed See why each corrected part needs to change. Review your writing with explanations, rather than just looking at the corrected answer. ■ Ask AI About Your Diary Ask AI any questions you still have after a correction. Explore nuances, grammar, alternative wording, and more natural ways to express yourself. ■ Review Your Mistakes Review by writing sentences in exercises based on corrections from your diary. Practice reducing repeated mistakes and reinforcing what you've learned. ■ Look Back With Weekly Reports Review your diary entries, AI chats, words used, and words used for the first time each week. See how many days you've practiced and how much you've done to help build a learning habit. ■ Check Your English Level With CEFR Analysis Analyze your diary against CEFR levels to get an indication of your English proficiency. See an overall assessment and breakdowns covering vocabulary, grammar, and verb forms. This feature is currently available for English learners. ■ Learn by Chatting With AI Characters Talk with AI characters such as Zena, Zeb, Leon, and Mari by text or voice. Build on topics from your diary or discuss a topic you enjoy to get more practice using the language. ■ Learn in 13 Languages Study English, Korean, Japanese, Chinese, Spanish, German, French, Italian, Portuguese, Dutch, Polish, Swedish, or Tagalog. ■ Share Diaries With a Team Join a team to share diary entries and exchange comments with others learning the same language. Learning together can help you keep going when it's hard to stay consistent on your own. This feature is currently available for learners of English, German, and Korean. ■ Get Daily Support From Zena Zena supports you with comments based on your learning activity. Start with a short diary entry and find encouragement to keep learning each day.
