How to check grammar with AI

What is the AI Grammar Checker?
The AI Grammar Checker analyzes your text for grammar, spelling, punctuation, and style errors. Unlike basic spell checkers, it understands context and catches mistakes that simple tools miss.
Paste any text and get instant corrections with clear explanations. Each fix tells you why the change was made, so you learn the rules and improve your writing over time.

More than spell check
Your browser's spell checker catches obvious typos but misses context-dependent errors. It won't flag 'their' when you meant 'there,' or catch subject-verb agreement issues. This tool understands the meaning of your sentences.
The AI also explains each correction. Instead of just fixing 'would of' to 'would have,' it tells you why. This turns every error into a learning opportunity, especially valuable for non-native speakers and students.
How to check your grammar
Checking grammar takes just a few steps:
- 1
Paste your text
Enter the text you want to check. Works with emails, essays, reports, social posts, or any written content up to 5,000 words.
- 2
Click Check Grammar
The AI analyzes your text for errors in grammar, spelling, punctuation, word choice, and style.
- 3
Review corrections
See the corrected text with all fixes applied. Each correction includes an explanation of the rule and why the change improves your writing.
- 4
Copy and use
Copy the corrected text for your document, email, or publication. Apply what you learned to future writing.
What errors does it catch?
The grammar checker identifies a wide range of writing issues:
Grammar errors
Subject-verb agreement, tense consistency, pronoun usage, sentence fragments, run-on sentences, and modifier placement.
Spelling and word choice
Typos, commonly confused words (their/there/they're, affect/effect), and context-aware spelling corrections.
Punctuation issues
Comma placement, apostrophes, quotation marks, semicolons, and other punctuation rules.
Style improvements
Wordiness, passive voice overuse, awkward phrasing, and readability issues that weaken your writing.

Tips for effective grammar checking
Check your writing after completing a draft, not while writing. Stopping to fix every error interrupts your flow. Write first, then run the grammar check on your finished text for a clean final review.
Pay attention to the explanations, not just the fixes. If you keep making the same mistake, read why it's wrong. Understanding the rule prevents future errors. The grammar checker is a learning tool, not just a cleanup service.
Don't accept every suggestion blindly. The AI is highly accurate, but you know your intent. Sometimes unconventional grammar serves a purpose, especially in creative writing or when matching a specific voice. Review each change and decide if it fits your goals.
