AI Grammar Checker

The AI Grammar Checker provides comprehensive writing analysis that goes far beyond basic spell-check. It examines your text for grammar mistakes, spelling errors, punctuation issues, and style problems — then explains each issue so you understand why a correction is needed. Powered by advanced AI, it catches nuanced errors that rule-based checkers miss, including context-dependent word choice, subject-verb agreement in complex sentences, and misplaced modifiers.

Every check returns a writing score out of 100, giving you an at-a-glance assessment of your text quality. Issues are categorized by type — grammar (blue), spelling (red), punctuation (yellow), and style (purple) — so you can see your weakest areas and improve over time. The corrected text is provided in full so you can copy and use it immediately, while the issue-by-issue breakdown teaches you the rules behind each correction.

Four style modes tailor the analysis to your context. General mode applies standard rules. Academic mode enforces formal tone, avoids contractions, and checks for scholarly conventions. Business mode prioritizes clarity, directness, and professional language. Creative mode allows more stylistic freedom while still catching genuine errors. Multiple languages are supported for international users.
