Free online proofreader
Paste a longer draft for a complete proofreading pass across grammar, spelling, punctuation, and consistency. PromptDC cleans the copy while respecting its original voice and argument.
Last quarter, our support team answered 2,418 tickets. Response times improved by 18 percent; however, customer satisfaction remained unchanged. The results suggest we should review the survey’s wording before the next report.
Why the rewrite is better: The proofread aligns every verb with the past reporting period, corrects subject-verb agreement and possession, and repairs punctuation around the transition.

Why the rewrite is better: It standardizes capitalization, list construction, time formatting, and singular references so the practical details read as one consistent notice.
Proofreading is the final quality check after the ideas and structure are already settled. This tool looks across multiple sentences for details that a single-line check can miss: shifting tense, inconsistent capitalization, repeated typos, uneven list punctuation, and agreement errors. It suits emails, essays, proposals, and articles that need polish rather than a new direction. A small number of runs are available here without registration, while PromptDC can proofread selections inside desktop applications and editable browser fields when you write regularly.
