Lingueez helps you build vocabulary across languages and actually remember it. Add a word the moment you meet it — from any app, with a global shortcut — and Lingueez looks up its definition and translation for you. It then turns your personal word list into spaced-repetition flashcards that resurface each word right before you'd forget it, so your study time goes where it's needed most. And when recognizing a word is no longer enough, the quiz asks you to pick the right answer — or type it out yourself, in either direction. Beyond flashcards, Lingueez reads your words aloud with natural text-to-speech and generates short reading passages built from the vocabulary you're learning, so you see every word in real context. Your library is yours: everything works offline, with no account required. Sign in only if you want your words and progress synced across devices. Free and open source. No ads, no subscription.
