Grammar Check

Grammar Check is an online AI proofreader that highlights grammar, spelling and punctuation mistakes and fixes them individually or in one click. It handles four English variants and six other languages, and the same site bundles an AI humanizer, AI checker, plagiarism checker, summarizer and paraphraser.

Grammar Check is a web based proofreading tool that scans text for grammatical, spelling and punctuation errors and offers corrections. The homepage presents it as a single purpose checker with a wider toolbox attached: an AI Humanizer, an AI Checker, a Plagiarism Checker, a Punctuation Checker, an AI Summarizer and an AI Paraphraser all sit in the same product. The core checker is positioned for non-native English speakers in particular, and it accepts four English variants (US, UK, Canadian and Australian) alongside Spanish, German, French, Portuguese, Dutch and Italian. In practice the workflow is short. Text is typed, pasted or uploaded as a file or image, and the tool then highlights grammar, spelling and punctuation problems with a count for each category. Each flagged mistake carries a suggested replacement that can be accepted individually, or the Fix All Errors button can clear the whole document at once. A settings panel lets users limit checking to specific error types, group consecutive mistakes into one suggestion, turn on auto fix, and build a personal dictionary of words to ignore. History, keyboard shortcuts and a word counter support longer editing sessions. Students proofreading essays and assignments, authors reviewing manuscript chapters, and bloggers cleaning up posts before publishing are the audiences the homepage names. Long-form and complex writing are explicitly supported, which makes the tool reasonable for anyone producing multi-paragraph drafts rather than the odd sentence. The competitive picture is straightforward. Grammar Check is a lighter alternative to full writing suites: it does not claim deep style rewriting or document collaboration, and the free tier is the main draw for casual users. The paid plans focus on credit volume, speed and the removal of daily limits rather than on extra language intelligence. Anyone who needs plagiarism and AI detection in the same place will find those tools bundled here, while teams wanting editor integrations should look elsewhere, because the site describes none.
