Vocab Flashcards

Select a word, look up its English-English meaning, and review it as a spaced-repetition flashcard.

Look it up once. Remember it forever. Learning new vocabulary usually means breaking your reading flow to search for definitions and write words down. Vocab changes that. Designed for power readers, ESL learners, and students (GRE/TOEFL), Vocab lets you capture and memorize words without ever leaving the page you are reading. How it works: Highlight any unfamiliar word, press Cmd/Ctrl+Shift+Y (or right-click), and an instant dictionary card will pop up. The word is silently saved, and our spaced-repetition system will help you memorize it later. Key Features: ⚡ Frictionless Capture: Look up words in a fraction of a second. No tab-switching required. 🧠 Smart AI Definitions: Say goodbye to confusing dictionary jargon. Get a clear, accurate definition, an "explain it simpler" fallback, and helpful synonyms/antonyms. 🔄 Spaced Repetition Review: Open the extension popup to review your saved words. Vocab brings them back on a proven schedule (1, 3, and 7 days) until they are permanently locked in your memory. 📖 Sentence-First Learning: Rote memorization is boring. Vocab tests you by showing the target word inside a natural example sentence, forcing you to recall the meaning from context. 🧩 Learn in "Chunks": Expand your fluency beyond single words by generating common phrases and collocations related to your saved vocabulary. 📱 Seamless Cross-Device Sync: The extension works completely offline on its own. Or, connect a free account to sync your progress seamlessly to the injaoonja.nl web app so you can review on your phone. Stop making lists you'll never look at again. Install Vocab and let your daily reading naturally build your vocabulary.
