Voca-Voca: English Vocabulary Builder, Dictionary & Flashcards

Grow your English vocabulary as you read. Highlight any word for instant definitions, pronunciation, and spaced-repetition review.

Grow your English vocabulary naturally while you read. Voca-Voca is a simple, focused dictionary and vocabulary tool for anyone who reads in English — from native speakers looking to sharpen their precision to learners building their foundation. How it works: highlight any word on any webpage to instantly see its definition, pronunciation, what part of speech it is, and real usage examples in a clean side panel, without ever leaving the page you're on. Every word you look up is automatically saved to your personal collection along with the original sentence and source — so when you review it later, you remember not just what the word means, but how it was used in the specific context you found it in. Your collection becomes a personal library of words you've encountered in articles, news, novels, research papers, or anywhere else you read online, and we have spaced repetition, spelling, and flashcards on top of it to make sure you memorize these words and start using them organically in your daily life. Any word, any level. Add a word you've known for years but want to use better, or a word you've never seen before. The same flow handles both — there are no levels, no filters, no judgment of any kind. Your vocabulary is your own, and all you can do is help yourself build on it and help the future you express yourself better in writing and speech. Review your saved words with built-in spaced-repetition flashcards, the same memory science used by Anki and Quizlet, so the words you collect actually stick. Practice with audio pronunciation, multiple-choice prompts, and typing modes. The algorithm schedules each card at the moment you're about to forget it, so your study time goes to the words that need it. Your saved words sync across devices through the cloud. Collect on your laptop while reading the morning news, then review on your phone during your commute with the companion Voca-Voca iOS app. ———————————————————————————— WHO VOCA-VOCA IS FOR — Readers who run into unfamiliar words and want to actually remember them — Writers, journalists, editors, and anyone whose work depends on precise language — Students preparing for the SAT, ACT, GRE, LSAT, MCAT, or graduate exams — English learners preparing for IELTS, TOEFL, or Cambridge exams — University students reading academic papers, journals, and dense nonfiction — Lifelong readers of literary fiction, philosophy, science writing, or history — Professionals reading news, reports, and industry publications — Bilingual readers and anyone who simply wants a bigger vocabulary ———————————————————————————— HOW IT WORKS 1.
