What the Grammar Checker Reviews Before You Copy
Grammar correction is strongest when it keeps the original meaning. Use these cases to decide whether a suggestion is a grammar fix, a clarity edit, or a style choice.
| Input situation | What gets checked | Best next step |
|---|---|---|
| Sentence with subject-verb or pronoun mismatch | Agreement, singular and plural forms, pronoun reference, and common verb-form errors. | Accept the correction when it preserves who did what and does not change the subject. |
| Paragraph with tense shifts or awkward flow | Tense consistency, parallel structure, clause order, and transitions that make the sentence easier to read. | Review whether the timeline and tone still match your draft before copying. |
| Specialized, informal, or creative writing | Likely grammar errors while allowing that dialogue, brand terms, names, and creative fragments may be intentional. | Keep intentional style choices and manually verify technical terms, names, and citations. |
Accuracy, Style, and Privacy Notes

Style can be intentional
Dialogue, marketing copy, informal messages, and creative writing may intentionally bend grammar rules. Keep intentional style choices when they serve the reader.
Language settings matter
Grammar conventions differ by language and region. Choose auto-detect or the closest language option so the checker interprets the text correctly.
Sensitive text
Avoid pasting passwords, private IDs, confidential client information, legal secrets, medical records, or unpublished private documents into any online writing tool.
