1. Lingueez - Vocabulary Builder

Build a vocabulary that actually stays with youFree and open source. No ads, no subscription.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.Key features:Instant capture — a global hotkey adds a word from any app, with the translation and definition filled inFlashcards — SM-2 spaced repetition, custom decks, and an audio mode that flips cards in time with the voiceQuiz — multiple choice or typed answers, in both directions, with instant feedbackRead-aloud — natural text-to-speech in 65 languages, plus MP3 exportReading — import from files, the web, Wikipedia, or RSS, with side-by-side translation and synced audioStatistics — status breakdown, daily streaks, and progress over time105 languages for your words, 32 for the interfaceImport and export — Excel in; PDF, Excel, CSV, MP3, or Anki-ready TXT outWorks offline, with optional cloud sync
