AIと作る英単語帳 WordBook.AI

The AI ​​transforms the words you enter into your personalized English vocabulary list.

WordBook.AI is an English vocabulary app that automatically generates meanings, example sentences, collocations, and even the differences between synonyms, simply by entering the English words you want to learn. Unlike commercially available vocabulary books where you memorize "words chosen by others," you can learn only the words you need right now, with a deep understanding.
