Grammar Checker
Paste your text — grammar, spelling and punctuation corrected in seconds. It works as an online proofreader too: the same check proofreads essays, emails and papers.

How it works
1. Paste your text (up to 5,000 characters) and press Check grammar.
2. Review each suggested change against your original — changes are shown one by one, and you decide to keep the correction or your own wording.
3. Copy the result. Your text is processed for the check and never stored.
What it checks
Grammar: subject–verb agreement, tenses, articles and word order. Spelling: typos, doubled words and homophones. Punctuation: commas, apostrophes and sentence ends. Clarity: awkward phrasing is smoothed only when the meaning stays the same.
It's an AI check, not a rulebook: it can miss things and occasionally suggests a change you'll want to reject — that's what the review step is for. It won't rewrite your style or pad your text.
When to use it
Before submitting anything where mistakes cost credibility: applications, emails to clients or professors, essays, listings and posts. For a full rewrite in a different tone, use the paraphrasing tool instead; to just count words and characters against a limit, the word counter does that as you type.
Free, without an account
Every visitor gets a generous number of free checks per day — no signup, no ads. Unlike the counters on this site (which run entirely in your browser), this tool sends your text to an AI model for processing. It is processed and immediately discarded: never stored, never logged, never used for training.
Is my text stored anywhere?
No. Your text is sent to the AI model, checked, and the correction is returned — it is processed, never stored. We keep no copies, no logs of content, and never use your text for training.
What does the grammar checker fix?
Grammar, spelling, punctuation, and awkward phrasing. It keeps your meaning and tone; it doesn't rewrite your voice. For a stronger rewrite, use the Paraphrasing Tool instead.
Does it work in languages other than English?
Yes — paste text in most major languages and it will correct in the same language. The interface itself is available in 38 languages via the footer switcher.
Can it explain what was wrong with my sentence?
Yes. After a check, use “Explain the fixes” to get a numbered list of the errors it found — each with the correction and a one-line reason. Like the check itself, your text is processed for that one request and never stored.
Is this also a spell checker?
Yes. The same check fixes spelling alongside grammar and punctuation — there's no separate spell check tool to run. Typos, doubled words and wrong homophones (their/there) are corrected in one pass.
Can I use this as an online proofreader for my essay, or as an essay checker or paper checker?
Yes — an essay checker or paper checker here means the same review-first grammar workflow: paste your draft, run one check for grammar, spelling, punctuation and unclear phrasing, then accept or reject each change against the original. It does not judge your argument, verify sources or citations, or predict a grade; a human read is still worth it before submission, and your teacher’s style and citation requirements are yours to check.
