What it actually is

Built on Tatoeba sentences, it drills words in context by frequency band across 50+ languages and 170+ language pairings, with a genuinely generous free tier. It explicitly starts where beginner apps end, so it is the natural 'what now?' answer for someone who finished a Duolingo tree. Sentences are crowd-sourced and occasionally awkward or oddly specific, and it teaches nothing about grammar explicitly.

Who it suits

Learners who already have a beginner course behind them and need thousands of words to stick in real sentences. It works best as a daily 10-20 minute habit alongside something that gives you listening and reading input, and for anyone studying a less common language where good vocabulary apps are scarce.

Who should skip it

Absolute beginners, who will be guessing at sentences they cannot parse, and anyone who wants explanations of why a form is used. It also trains recognition far more than production, so it will not get you speaking or writing on its own.

  • Glossika

    Pick Glossika instead if your goal is listening and speaking whole sentences aloud rather than recognising the missing word on screen.
