Vocalabs: Highlight to Flashcard

Highlight any word on the web to make a flashcard, then review it anywhere with science-backed spaced repetition.

You look a word up, and by tomorrow it’s gone. Vocalabs catches words while you read and brings them back until they stick. Highlight anything on any page. You get a flashcard with the definition, the pronunciation, and the sentence you found it in — the word in the context that made you care about it, not someone else’s list. HOW IT WORKS Highlight a word. Alt+S, or right-click. Vocalabs builds the card from the page. Review a few minutes a day. Alt+R. Cards come back just before you’d forget them, on the same algorithm behind Anki. The ones you find easy get out of your way. FIVE WAYS TO BE ASKED Recognising a word isn’t using it, so Vocalabs asks from either direction -> word to meaning, meaning to word, or the sentence with the word blanked out. Turn on typing for letter-by-letter feedback. WORKS OFFLINE Over 40,000 English words ship inside the extension, so a lookup never waits on the network. Interface in 17 languages, right-to-left included. REVIEW ANYWHERE Cards sync to vocalabs.app/app. Add it to your phone’s home screen and review on the bus. PRIVATE BY DESIGN Vocalabs reads the words you highlight and nothing else. No browsing history, no page content, nothing sent anywhere but the word being looked up. Your cards stay on your device unless you sign in. FREE, including the offline dictionary and every review mode. Pro lifts the card limit. Bring your own AI key for richer definitions if you want — it goes straight to your provider.
