Language Diary: LangJournal7.11.17 - App Store

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.
