Not every suggestion is a mistake: solid underlines are errors, dashed are improvements, dotted are optional style ideas — you decide what to accept.

Pick Academic as the writing goal and this essay checker judges your essay by the standard it will be graded on: formal register, no contractions, careful punctuation and clear sentences. You also see why each issue matters, so the same slip doesn't follow you into the next essay. Your text is processed and discarded right after; nothing is stored on our servers.

A Free Grammar Check That Teaches, Not Just Fixes

Paste up to 3,000 words and this online grammar checker underlines every issue by category — grammar, spelling, punctuation, clarity, style — each with a plain-language explanation and your choice to accept or reject. It's a grammar corrector, punctuation checker, and sentence corrector in one, free with no signup and no ads.

English grammar check is the most popular use, but the AI works in 25+ languages and answers the everyday question behind every paste: "is this sentence grammatically correct?" — and if not, exactly why.

Corrections You Can Understand and Control

A silent grammar fixer asks for blind trust. This writing checker shows its work:

Explanation for Every Fix

Click any underline and see what was wrong, the correction, and why — "plural subject takes 'were'", not just a silent swap. You learn while you edit.

Accept / Reject Each Change

Every suggestion has its own Accept and Dismiss buttons. Keep your voice where the checker guessed wrong — or hit Accept all for the instant one-click fix.

7 Categories, Color-Coded

Grammar, spelling, punctuation, clarity, style, word choice, consistency — each with its own underline color and a filter chip, so you can review one kind of issue at a time.

Severity, Not Panic

Solid underline = a real error. Dashed = an improvement. Dotted = optional suggestion. Stylistic preferences are never dressed up as mistakes.

Writing Goals & Tone

Pick Academic, Business, Casual, or Creative — the checker adapts: contractions are flagged in an essay, welcomed in a chat message. Tone detection shows how your text reads.

Writing Score

One number for the document, four subscores — Grammar, Clarity, Style, Readability — and watch it climb as you accept fixes: 72 → 94 feels good for a reason.

Beyond typos

Clarity and Style, Flagged Gently

Correct grammar can still be hard to read. The checker looks past the commas.

Overly long sentences get a purple flag with a one-click split. Passive voice, repeated words, and wordy phrases like "in order to" or "at this point in time" are marked as improvements — with the shorter version one tap away. Click ↻ on any sentence for a full rewrite: Improve, Simplify, Shorten, Make Formal, or Make Natural.

Severity matters: "recieve" is an error. "Consider splitting this 38-word sentence" is advice. This checker keeps the two visually distinct, so you always know whether you're fixing a mistake or making a choice.

What Is an AI Grammar Checker and How Does It Work?

An AI grammar checker reads your text the way an attentive editor would: it parses each sentence, spots grammar, spelling, and punctuation mistakes, and suggests corrections. Unlike old rule lists that had to be written by hand for each language, grammar AI learned these rules from billions of sentences — which is why one model can correct grammar in English, Spanish, French, German, and 20+ other languages, and explain each fix in the language you wrote in. Modern checkers also go further than "correct grammar": they evaluate clarity, tone, and style, because "technically correct" and "reads well" are two different standards.

Why explanations matter

A correction you don't understand is a correction you can't trust — and one you'll need again tomorrow. That's why every fix here comes with a short reason: subject–verb agreement, a homophone mix-up, a comma rule. Over time, the checker makes itself less necessary. We consider that a feature.

Errors vs. choices

"Recieve" is wrong in every context. Passive voice is not — sometimes it's exactly right. A good checker keeps that distinction visible: errors get solid underlines, improvements dashed, optional style ideas dotted. You stay the author; the tool stays the assistant.

No catch

A Grammar Checker Free of Ads, Paywalls & Dark Patterns

Grammar Checker FAQ

Paste it above and pick the Academic goal. One essay grammar check then goes through grammar, spelling, punctuation, clarity and style (each issue comes with an explanation and a one-click fix).

Not the way a professor would, but the writing score acts as a fast essay rater: it shows how well written your essay is. Many students use it as an essay grader for the language and then decide for themselves how good their argument is.

Yes, in parts. The paper checker takes in 3,000 words at a time, which means a standard undergraduate essay can be checked in one go. Longer dissertations or theses are broken into sections and checked one by one.

Yes. As an essay editor it flags contractions, casual phrasing and vague constructions that graders penalise, alongside the errors an essay grammar checker catches.

It won't write for you. Use it as an essay corrector and essay fixer: it flags issues and explains them, like an essay improver for grammar and style. For “improve my essay” in the rewording sense, there's the Paraphrasing Tool (one click away).

The college essay checker makes sure you don’t leave small mistakes in your personal statement or application essay. It is not a college essay rater for content, so get an essay review from someone you trust as well.

Yes to both! There’s no sign up required on this essay editor website, and the text you submit is checked but not saved or used for training. If you’re looking for the best essay grader, you likely want quick essay feedback, which you can get here for free.

Responsible Use of Clever Grammar Checker

A grammar checker is an assistant, not an authority. Review suggestions before accepting them — especially in legal, medical, academic, or other high-stakes writing, where a "correction" can change meaning.

Explanations are provided to help you judge each fix, but you remain the author, and the final call on wording, tone, and accuracy is yours.

Follow the rules of your school, university, or workplace regarding AI-assisted writing. Clever Grammar Checker is provided as a writing aid on an "as is" basis.
