It works for both US English and UK English, so you can keep a consistent style. If you want help with drafting new text, try our AI writer after you fix your grammar. Many people search for phrases like “check my grammar online free,” “free grammar checker no sign up,” or “free grammar checker no login.” If that is you, this page gives you a fast and easy way to start a check.

Editing tips for better results
- Keep sentences short when the idea is complex. Then add longer lines where the idea is simple. This balance helps flow and clarity.
- Choose US or UK English at the start. Do not switch styles in one document.
- Read your text out loud. If you need to stop for breath, consider a split or a comma.
- After grammar fixes, check clarity with our readability checker. It can point out long lines and hard words.
- For school or publishing, run a final originality scan with the plagiarism checker link above.
Compatibility and alternatives
Our tool runs in your browser and works on most devices. The Chrome extension brings checks into your web apps. Many writers use it as a Grammarly alternative. Others see it as a LanguageTool alternative or a ProWritingAid alternative for quick tasks. You can still use built-in tools like Microsoft Editor, Google grammar check, or Word grammar check online. But this AI grammar checker can give extra detail and clearer suggestions when you need more help.
Scope, privacy, and fair use
This grammar fixer is a helpful assistant, not a human editor. It will not replace your judgment. Please review each change and keep your voice. Do not paste sensitive data. We process your text to generate suggestions, and we aim to protect your privacy. For legal, medical, or very technical writing, ask a human proofreader as a final step. If your document is very long and you want a grammar checker no word limit, try checking in sections so you can focus on the parts that matter.
