AI Grammar Checker

Check grammar, spelling and punctuation errors with AI-powered suggestions.

The errors that survive proofreading are the ones spell check can't see: "could of" instead of "could have", a verb that stopped agreeing with its subject three edits ago, a comma splice in the middle of a long sentence. Because every individual word is spelled correctly, only a checker that reads the surrounding sentence will flag them. Each suggested fix here comes with a short explanation of why, so the same mistake gets rarer over time.

What Gets Checked

Grammar - Subject-verb agreement, tense consistency, article usage and pronoun reference errors
Spelling - Misspelled words, common typos and confused homophones (their/there/they're)
Punctuation - Comma placement, apostrophes, semicolons and quotation marks
Style issues - Wordy phrases, passive voice overuse and redundant wording
Clarity - Confusing sentences and ambiguous phrasing that could be clearer

How It's Different From Basic Spell Check

Your browser's built-in spell check looks at individual words in isolation. It'll catch "teh" but not "I could of done it" because every word there is spelled correctly. AI grammar checkers read the sentence around the mistake. That helps with context, tense and wording that sounds clunky even when it is technically correct.

When A Grammar Checker Helps Most

Use it when you are editing emails, school drafts, blog posts, product copy or support replies. It is especially useful after you have already written the first version. The tool can catch small issues you stop seeing after reading the same paragraph too many times.

It is not a replacement for judgment. Creative writing, dialogue and brand voice can break normal grammar rules on purpose. Read each suggestion before accepting it.

Tips for Better Results

Paste your complete text rather than fragments. The AI needs context to catch errors properly. Don't blindly accept every suggestion - sometimes the AI misreads your intent, especially with creative writing or intentional style choices. Review each suggestion and apply the ones that make sense for your writing.

Frequently Asked Questions

Is this better than my browser's built-in spell check?

It catches more types of issues. Browser spell check is good for misspelled words. This also looks at context, punctuation, wordy sentences and confusing phrasing.

Does it work for languages other than English?

Right now it is tuned for English. It may still notice simple issues in other languages, but you should not rely on it for multilingual editing yet.

Can I use a chatbot like ChatGPT instead?

You can, but it's clunky. You'd paste your text, ask it to check grammar, then manually apply fixes. A dedicated grammar checker highlights errors inline and lets you fix them with one click. It's a much faster workflow.

Is my text private when I use this?

Your text is sent to an AI API over an encrypted connection. WordCounterz does not keep it after the check is done, but the AI provider processes it under its own terms.

Should I accept every suggestion the tool makes?

Review them one by one. Grammar checkers sometimes flag intentional style choices or misread creative writing. The tool is a helper, not the final authority on your writing.
