SentenceCoach
Chinese sentence corrections with English explanations
Practise Chinese writing with corrections, plain-English explanations and pinyin. SentenceCoach combines a free, no-sign-up sentence checker with HSK writing practice, vocabulary guides, grammar references and measure-word examples. AI feedback can make mistakes.
Hi Product Hunt! I built SentenceCoach for learners who know individual Chinese words but find it hard to put them into a natural sentence.
Write a sentence, get a minimal correction, then read a short English explanation and pinyin. There are also HSK writing prompts, vocabulary guides, measure-word examples and sentence-ordering practice. The checker is free with usage limits, and no account is needed.
Feedback is generated with DeepSeek and can be wrong; this is a practice aid, not an official HSK grader or a replacement for a teacher. Submitted text is sent to the model provider, so please avoid personal information. Guides are AI-assisted and edited; sources and limitations are described on our About page.
I would especially appreciate feedback on whether the explanations help you understand the mistake, and examples where the checker makes an unnecessary correction.
