In their own words
Clozemaster
Clozemaster is a language-learning service built around fill-in-the-blank sentences in context. Learners answer by selecting a choice or typing the missing word, then review sentences again through spaced practice and word-frequency progress tracking. The service lists 75 languages, thousands of sentences in more than 50 languages, and over 170 language pairings. It runs on the web, Android, and iOS, with personalized review and offline lessons. Some sentences have ChatGPT explanations by default, while others can generate an explanation when requested. Sentence and translation data comes from Tatoeba’s user-curated, CC-BY dataset, which may contain errors. The Free plan costs nothing and allows 30 sentences per day.
