What our users say
"There are lots of words I understand but not confident in using myself. I used to use a flashcard app for vocabulary, but haven't for the last couple of years. SentenceLab is better than just recognizing the word on a flashcard."

Frequently asked questions
Everything you need to know about SentenceLab
Do I need to know any Chinese to start?
SentenceLab is designed for intermediate learners (around HSK 4-6 level). You should be comfortable reading Chinese characters and understanding basic sentence structure. If you're just starting out with Chinese, we recommend building your foundation with a beginner course first, then using SentenceLab to practice active production once you have a solid vocabulary base.
What happens after the 7-day free trial?
After 7 days, you can choose to subscribe for a paid plan. No credit card is required for the trial, so you won't be charged automatically. If you don't subscribe, you'll keep access to your progress and data—we never delete your work.
Can I cancel anytime?
Yes, absolutely. Cancel your subscription anytime from your account settings. There are no cancellation fees, and you'll keep access until the end of your billing period. Your progress and all your sentences are saved permanently.
How does the feedback work?
When you write a sentence, our tool checks your grammar, word usage, and natural phrasing. You get instant corrections with explanations of why something is right or wrong. It also suggests more natural ways to express your ideas and explains cultural context when relevant.
Is this better than apps like Duolingo or HelloChinese?
Apps like Duolingo and HelloChinese are excellent for building vocabulary and recognition skills. SentenceLab picks up where they leave off—helping you actually use the words you've learned. Many users find that other apps get them to intermediate level, then SentenceLab helps them break through the plateau by focusing on active production.
I’m worried about writing complete sentences myself incase I make mistakes.
That's exactly the point! Making mistakes is how you learn. The feedback system helps you understand what went wrong and how to fix it. Every mistake is a learning opportunity. In fact, learners who make and correct mistakes progress faster than those who only study "perfect" examples.
Do I need to type in Chinese characters?
Yes, you'll write sentences in Chinese characters. Most learners use pinyin input (typing "nihao" converts to "你好").
