Chinese Grammar Checker
Chinese Grammar Checker is a free Chinese grammar checker that corrects sentences and explains mistakes in English.
SentenceCoach is a free Chinese grammar checker designed for learners. Users paste a Chinese sentence to receive corrections for word order, particles like 了 and 的, measure words, and look-alike words. The tool makes the smallest possible correction to fix errors while keeping the original meaning, and it also accepts both simplified and traditional characters. Corrections are accompanied by plain English explanations, pinyin, and translations. It uses a large language model combined with specific rules for learner errors, and users can set their HSK level to flag advanced words. Sentences can be checked without an account up to a fair-use hourly limit.
