About Common Writing Mistakes Checker
What this page solves
Spot a small set of common English writing patterns locally without uploading a draft.
Common Writing Mistakes Checker uses simple English regular-expression rules. It flags lowercase I, repeated spaces and words, sentence capitalization, selected word confusions such as your/you’re and then/than, could of, and rough punctuation/style patterns. It lists suggestions for manual review. It does not perform general spelling, subject–verb agreement, semantic analysis, or comprehensive grammar checking. Some suggestions, including a/an and passive-voice heuristics, can be false positives. No matching patterns does not mean the text is error-free. Proofread independently; this is not a replacement for a full language checker.
