What you get
Everything you need to learn from a text
Bring the Mandarin you actually care about. LottaLang turns it into vocabulary, explanations, practice and review.
Every sentence, explained
Each line is split into words with pinyin or zhuyin and dictionary meanings, so you can read along instead of looking things up.
Flashcards that adapt
Keep the words you want. Spaced repetition brings each card back just before you would forget it.
Listen and shadow
A natural neural voice reads every line, and shadowing mode walks you through a dialogue one sentence at a time.
Taiwan first
Traditional characters, Taiwanese readings and zhuyin by default. Simplified characters and mainland readings work just as well.
Practice that sticks
Rebuild shuffled sentences, take quick quizzes, check your level and export your words to Pleco.
How it works
From a text to words you can use
Bring a text
Paste a dialogue or an article, or import the subtitles of the episode you are watching.
Study what matters
See which words you know, which are new and how hard the text is for you, then add the useful ones to your deck.
Review and speak
Short daily reviews, sentence games and shadowing turn new words into ones you can use.
