Key Features of Pengword โ–  AI-Powered Input Assistance Simply enter a word, and the AI automatically generates its meaning, part of speech, phonetic symbols, example sentences, synonyms, and antonyms. Audio playback for both words and example sentences is also available. Currently, the app supports the following four languages: - English, Swedish, Spanish, French and Italian The following premium features are available to subscribers: - Customizable Example Sentences: Specify the length and tone of generated sentences. - High-Quality Audio: Natural, human-like voice synthesis for playback. โ–  Spaced Repetition Learning The app prompts you to review registered words just as your brain is about to forget them, based on the forgetting curve. To improve retention, Pengword offers multimodal review methods, including: - Multiple-choice quizzes - Keyboard input - Fill-in-the-blank sentences - Listening exercises โ–  Grow Your Penguin as You Review This feature is a personal passion project of the developer! As you review words, your penguin egg will hatch and grow. You can view your collection of grown penguins in the Gallery. This adds a touch of fun to the often-monotonous task of memorization. -------------------------------------------------------------------------- "Scout Mode": Discover New Words While Pengword's primary focus is registering words you want to learn, Scout Mode is designed for those times you want to encounter something new. In Scout Mode, the AI suggests words based on your selected learning goals and level (e.g., Goal: "TOEIC," Level: "600โ€“750"). You can sort through these suggestions by swiping left or right to indicate whether you already know the word. Words you didn't know can be registered in bulk, with the AI instantly generating all definitions and example sentences for you. -------------------------------------------------------------------------- Recommended For: - Those looking to expand their vocabulary efficiently. - Anyone who wants to save time on manual flashcard creation. - Learners who want to review words at the scientifically optimal time. - Penguin lovers!
