What is Lingueez?

Lingueez is a free, open-source vocabulary trainer that helps you quickly save words, translate them instantly, and actually remember them. You can capture words from anywhere with a keyboard shortcut, read real articles inside the app, and turn every saved word into a flashcard. It supports spaced repetition, quizzes, audio practice, progress tracking, and AI-powered definitions or examples. Your vocabulary stays organized with tags, favorites, and learning statuses. It works across desktop, Android, the web, and e-readers, with optional cloud sync, backups, and import/export tools. It is local-first, can be used offline, and keeps your learning data private.
