AI Grammar Checker

Paste or upload your text into the grammar checker above and click Check Grammar. The tool scans it for grammar, spelling, and style issues, then returns a writing score plus a breakdown of every issue it found. Review the flagged issues, dismiss any you disagree with, and copy the corrected text when you are done. No sign-up is required for your first 3 checks.

Yes, it checks grammar, spelling, and style in one pass. Each issue it finds is sorted into one of these three categories with a count, so you can see at a glance where most of your errors are before you start fixing them.

Yes, spelling is one of the three categories this tool checks, alongside grammar and style. It flags misspelled words and commonly confused words, such as its versus its, and groups them under the Spelling tab so you can review them together.

Yes, punctuation errors are flagged under the Grammar category rather than a separate tab. Missing commas, incorrect semicolons, misplaced apostrophes, and other punctuation mistakes are caught in the same pass as grammar issues, so you do not need a separate tool to check punctuation on its own.

Yes, it works for essays, assignments, research papers, emails, and any other writing you paste in. Paste up to 1,800 words per check, and the tool flags grammar, spelling, and style issues with a plain-language reason for each one, so you can learn from the corrections as you fix them.

Tense shifts and subject-verb agreement are common grammar mistakes in student writing, and this checker's Grammar tab is built to catch structural issues like these, not just typos. It flags these alongside the punctuation and phrasing problems grouped under the same tab.
