【単語帳作りで、勉強した気になっていませんか?】 「わからない単語をノートに書き出す。」 「電子辞書で意味を調べて、赤シートで隠せるようにペンで書く。」 かつてはそれが王道でした。しかし、現代のスピードにおいて、その作業はあまりにも「時間」というコストがかかりすぎます。書き写すだけで30分、覚える時間は残り10分……これでは本末転倒です。 もう、単語帳を「作る」のはやめましょう。 これからは、「E-tango」があなたの代わりに作ります。 【E-tango の体験:アナログの手軽さを、デジタルの頭脳で。】 教科書、参考書、あるいは街で見かけた英字新聞。 気になったその瞬間、スマホをかざしてください。 ・Snap (撮る): 複数ページでも連続で撮影OK。 ・Extract (抽出): Googleの生成AI (Vertex AI) が、画像内の英単語を瞬時にリスト化。 ・Master (習得): その場であなた専用の「単語テスト」が完成。 「書く」時間を「見る・覚える」時間へ。E-tangoは、あなたの学習密度を劇的に高めます。 【機能ハイライト】 ・ 瞬間単語抽出: 複数枚の写真から一括で単語テストを作成。 ・ AI自動定義: 最新のVertex AIが単語の意味を自動生成・最適化。 ・ スマート分類: 学年別・レベル別に自動で整理整頓。 ・ 忘却防止システム: 定着度に合わせて出題頻度を自動調整。 さあ、E-tangoを始めよう。 紙の質感も好きだけど、効率は譲れない。そんな欲張りな学習者のために。 あなたのカメラを、最強の学習ツールに変えてみませんか? 利用規約(EULA) https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Key Features of Pengword ■ 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. ■ 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 ■ 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: "600–750"). 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!
