This ai proof reader checks grammar, punctuation, subject-verb agreement, and consistent style, without rewriting your tone or content, correcting actual errors and inconsistencies only, the way a dedicated proofreader would, not a full editor.
It reads the full text first, checks genuine grammar and punctuation errors plus internal inconsistencies like mixed date formats or switching spellings mid-document, and produces both a corrected version and an error list with location and fix for each, so you can learn the pattern.
If you name a style guide, AP, Chicago, or APA, it applies that guide's specific punctuation and formatting rules. It never changes word choice, tone, or content as part of a proofread, that's a different job, and it says so if asked to also improve the writing.
