A new method for learning Mandarin.
Mandarin Mosaic is a specialised app for sentence mining in Chinese. With sentence mining, you can get the best balance between flashcards and context:
- Learn new words in context so that you can immediately use them in a sentence
- Learn new words quickly without being overwhelmed by complexity
- Learn new grammar structures without the boring rote memorisation
Sure, you can study sentences in Anki, but intelligently picking sentences that are at just the right level of difficulty for you? Nothing like this exists.
This is why we created Mandarin Mosaic.
The app keeps track of your vocabulary. It knows what words you know. And it only shows you sentences with one new word. This makes it easier to remember and use new words in context.
Easily keep track of words you do and don't know.
Words which you don't know yet are highlighted in blue, and you can easily mark a word as known or unknown at any time.
With Premium, the app also syncs your vocabulary progress and sentence packs to the cloud so that you never lose anything.
