Clozemaster
Thousands of fill-in-the-blank sentences in 50+ languages.

Clozemaster is a language learning platform that teaches vocabulary through fill-in-the-blank (cloze) exercises using real sentences across 50+ languages. It uses spaced repetition to help learners retain words in context rather than in isolation. The app is free to use, with a Pro tier for advanced features, and is available on web, iOS, and Android.
Users fill in missing words in real sentences across their target language, with spaced repetition bringing sentences back for review at optimal intervals to build long-term retention.
