About Clozemaster
Clozemaster is a gamified language learning platform that helps intermediate and advanced learners build vocabulary through fill-in-the-blank (cloze) sentences sourced from real-world text. With 50+ languages, spaced repetition, and daily review goals, it complements apps like Duolingo by focusing on contextual sentence mining rather than beginner drills.
