Beaver The World is a language learning app.
Choose the language you want to learn from 41 languages, and then choose the theme from among sentences, words, and idioms.
You can customize your learning content by entering keywords of the situation you want to learn in, and then having AI create example sentences based on those keywords.
Once you've memorized the example sentences you've created, you can expand your vocabulary and expression skills while having fun with flashcards.
