Click Check Grammar to start
The Grammar Checker takes the text you paste in, sends it to a language model with a single instruction — fix grammar, spelling, and punctuation without changing meaning or tone — and returns the corrected version. You then read it, copy what you want to keep, and discard anything that reads off.
It handles the four error types that make writing look careless: grammatical errors (subject-verb agreement, tense slips, pronoun case), spelling including the homophone traps (their / there / they're, its / it's), punctuation (comma splices, missing apostrophes, mismatched quotation marks), and sentence structure (run-ons, fragments, awkward phrasing).
One honest limit: this isn't an editor. It fixes mistakes; it won't rewrite for clarity, tighten a flabby paragraph, or tell you that your third sentence contradicts your second. For that, read the output once yourself before sending or publishing.
Emails you'd rather not embarrass yourself with. Job applications, follow-ups to clients, replies to your boss, anything customer-facing. Three minutes through the checker is cheaper than one sloppy message.
Blog posts and articles before publishing. The cost of a typo in published content compounds — it stays visible to every reader who arrives via search for as long as the post is live.
Social media captions and bios. Short text gets read more carefully than long text. A single error in a 200-character LinkedIn post is more visible than the same error in a 2,000-word essay.
Drafts of important documents — cover letters, reports, proposals — before passing them to a human reviewer. Sending the checker's output to your editor saves them time on the basics and lets them focus on substance.

Most corrections are clearly right; the rest are judgment calls worth checking.
Copy the corrected text
Or copy just the parts you agree with, back to your own draft.
1. Comma splices. Two independent clauses joined only by a comma. "I went to the store, I bought milk" needs a conjunction or a semicolon: "I went to the store, and I bought milk."
2. Its vs. it's. Its is possessive; it's is short for "it is". The dog wagged its tail; it's a beautiful day. The most common error in professional writing.
3. Subject-verb mismatch. Plural subjects need plural verbs and vice versa. Watch for collective nouns and long phrases that hide the subject: "The list of recommended ingredients was long" — not were.
4. Their / there / they're. Possessive, location, contraction. The spell-checker won't catch these because each is spelled correctly — only context tells them apart.
5. Misplaced apostrophes. Apostrophes mark possession or contraction. They don't form plurals. "Photo's" is wrong; "photos" is right.
An AI grammar checker is fast, free, and right about the basics nearly all of the time. For everyday writing — emails, blog posts, captions, notes — that's enough.
A human proofreader does what AI still can't: catches factual errors, flags arguments that don't track, notices when your tone drifts halfway through, and pushes back on word choices that are grammatically fine but wrong for your audience. For high-stakes writing — published books, legal contracts, academic papers, anything you sign your name to with real consequences — the AI is step one, not the last step.
For everything in between, the answer is usually: run it through the checker, then read it aloud once before sending.
