Free Grammar Checker — Catch Every Error Before It Costs You

Whether you're writing a job application, a client email, a university essay, or a blog post — grammar errors are the one thing that can undermine an otherwise strong piece of writing. Readers notice them even when they don't consciously register them. Hiring managers filter candidates on them. Clients judge professionalism by them.

This free grammar checker catches the errors your eyes skip over — wrong apostrophes, mismatched tenses, missing articles, comma splices, and subject-verb disagreements. Powered by the LanguageTool open-source engine and tuned for both native and non-native English speakers.

What Gets Checked

• Spelling — catches typos and common misspellings
• Grammar — subject-verb agreement, wrong tense, incorrect verb forms
• Punctuation — missing commas, incorrect apostrophes, run-on sentences
• Articles — wrong usage of a, an, and the (critical for ESL writers)
• Style — wordy phrases, redundant words, passive voice overuse
• Confused words — your/you're, its/it's, then/than, fewer/less

The whole process takes under 60 seconds. No account, no extension, no subscription prompt.

Why It's Better Than Manual Proofreading

When you re-read your own writing, your brain fills in what you meant to write — not what's actually on the page. This is called the proofreading blindspot, and it affects everyone, including professional writers. A grammar checker has no expectations about your intent. It reads exactly what's there. That's why running your text through a checker after writing — not during — is the most effective approach.

Write first. Edit second. Check grammar third. In that order, your writing gets both authentic and polished.
