Highlight any word while you read online. Get the definition instantly, save it, and lock it into long-term memory with daily 5-minute practice sessions.
Every unfamiliar word is a chance to learn — here's how Voca-Voca helps
Highlight any word on any webpage. Definition, pronunciation, and examples appear in a sidebar — you never leave the page you're reading.
Each word is saved alongside the sentence where you found it and the source URL. Months later, you'll remember exactly where you learned it.
A proven algorithm shows you each word right before you'd forget it. You practice less, but remember more — that's the science of spacing.
Hear every word spoken aloud with auto-play. When you know how a word sounds, you're far more likely to use it in conversation.
Open the side panel and run a flashcard session during a coffee break. No app to switch to — spaced repetition lives right where you work.
Sign in with Google and everything — words, progress, streaks — syncs between Chrome and the iOS app in real time.
Research shows that short, daily spaced-repetition sessions beat hour-long cramming by a wide margin. The key isn't how long you study — it's how consistently you return.
Whenever you hit an unfamiliar word in an article, highlight it. Voca-Voca saves the definition and the sentence — zero friction.
Open the side panel during a break. Flashcards appear for words you're about to forget. Rate yourself and move on — done in minutes.
Words move from "seen once" to permanent memory. You'll start noticing them in conversation and using them without thinking.
Spaced repetition is backed by over a century of cognitive science, from Ebbinghaus's forgetting curve (1885) to modern research confirming that distributed practice produces stronger, longer-lasting retention than massed study.
Collect words on your laptop while reading articles or research. Then practice on your phone — on the train, waiting in line, wherever you have a few minutes. Your collection and progress sync automatically.
