LangJournal: English & Spanish Brazil L +4

LangJournal is an app designed to help you acquire language skills through the habit of keeping a diary. You can learn English, Korean, Japanese, Chinese, French, German, Spanish, Portuguese, and Dutch. The AI instantly checks your diary from perspectives such as "grammar, vocabulary, and syntax."

There's also a feature for learning with friends in teams. Teams are small, with five members each. You can join a team and exchange diaries and comments with users learning the same language. Continuing a diary in a foreign language might be challenging alone, but with friends, you can achieve it.

Enhancing writing skills makes LangJournal ideal for preparing for tests like TOEFL.
