Spell Check That Catches Real Words in the Wrong Place
score
All spell checkers will catch “teh”, but the harder errors are correct words used in the wrong context, such as their instead of there, form instead of from and complement instead of compliment. A dictionary-based spelling check won’t catch these, but because this ai spell checker understands context, it can. Your text is processed and then immediately discarded; 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:
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.
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.
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.
Solid underline = a real error. Dashed = an improvement. Dotted = optional suggestion. Stylistic preferences are never dressed up as mistakes.
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.
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.
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.

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.
A Grammar Checker Free of Ads, Paywalls & Dark Patterns
No blurred corrections behind a paywall, no ads between you and your text, no daily limits designed to annoy you into upgrading.

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.
