Clozemaster is a sentence-based language learning app focused on vocabulary acquisition. Instead of isolated words, you practice by filling in missing words in real sentences (“cloze” exercises). It supports 50+ languages and thousands of sentence pairs.
If you’re past beginner apps and want to actually understand native content, Clozemaster fills the gap. It’s especially useful for learners who already know basic grammar and want to scale vocabulary fast. Translators, expats, and self-directed learners tend to get the most value.
You choose a language pair and start completing sentences where one word is missing. The app uses spaced repetition, frequency-based word lists, and optional listening mode with text-to-speech.
