Turn words you look up into words you remember. Simple Wordbook is a personal vocabulary notebook for the words and phrases that matter to you. Collect useful language from work, travel, books or exam preparation. • Add a word and see an automatic translation in your chosen language. • Listen to its pronunciation. • Generate AI example sentences using your saved words, with translations. • Show or hide translations and check off words as you review. • Organize multiple lists, and touch and hold a word to move it to another list. Get started by choosing your native language for translations and adding your first English word. You can change both the wordbook language and translation language later in Settings. Available in Japanese, English, Spanish, French, German, Italian, Brazilian Portuguese, Korean, Simplified Chinese and Traditional Chinese. Make a little time for the words you want to remember. Translation and AI example generation require an internet connection. Review with quizzes to build a learning streak. The calendar shows learning days, your next goal and your best streak. If your streak breaks, you can optionally complete a rewarded ad to protect the displayed gap and continue it. Protected days do not add learning days. Wordbook and quiz features remain available without watching ads.
