Accuracy, Style, and Privacy Notes
Punctuation is partly rule-based and partly style-based, so review every correction before publishing.
Style differences
US and UK punctuation conventions can differ, especially around quotation marks. Choose the language setting that matches your audience.
Intentional voice
Short messages, marketing copy, poetry, and dialogue may use punctuation creatively. Keep intentional style choices when they fit the context, and use the suggested version as a proofreading draft rather than an automatic final answer.
Sensitive text
Avoid pasting passwords, private IDs, confidential client information, medical records, or legal secrets into any online correction tool.
