How to Use Simple Sentence Checker
Simple Sentence Checker is a first-pass proofreading tool. Paste a paragraph or several sentences, and the checker reports rule matches such as repeated English words, simple subject-verb agreement patterns, repeated Chinese phrases, and common Chinese issue patterns.
Read each warning together with the original sentence. The tool is intentionally conservative in scope: it points to places worth reviewing, but it does not rewrite your sentence or claim that every warning is definitely wrong.
Formula & Theory - Simple Sentence Checker
Issue count = repeated English word matches + simple agreement-pattern matches + repeated Chinese phrase matches + Chinese issue-pattern matchesThe checker uses regular expressions and rule lists. For English, it can catch patterns such as duplicated words and simple forms like she go. For Chinese, it now includes 1000+ explainable patterns for quantity redundancy, mixed sentence structures, missing-subject cues, negative-expression mistakes, mismatched two-sided wording, and similar first-pass review signals.
This approach is fast and transparent. Its tradeoff is that it cannot understand complex syntax, metaphor, dialogue, or deliberate repetition.
