Free Grammar Checker

A grammar checker that actually fixes things (not just points at them)

Most “free” grammar tools do the same annoying thing. They underline a word, maybe throw a vague message under it, and then you are stuck guessing what the correct version should be.

This page is built for the opposite workflow. Grammar Check + Instant Fixes (Not Just Highlights). Paste your text, get a cleaned up version back, and move on.

If you are also looking for other writing tools you can use in the same place, you can always jump back to the main hub on WritingTools.ai.

What this grammar checker catches (and why it matters)

Grammar mistakes are not all equal. Some make your writing look sloppy. Others change meaning, which is worse.

Here are the big ones a good grammar check should handle:

Grammar errors (the ones that quietly break trust)

Subject verb agreement, tense consistency, sentence fragments, run on sentences, and weird structure that makes a line hard to follow.

Spelling mistakes and typos

Misspellings, accidental duplicates, and common word mixups that spellcheck often misses.

Punctuation problems

Commas, apostrophes, quotation marks, and those tiny punctuation choices that change clarity fast.

Clarity and style cleanup

Not just “correct” English, but cleaner writing. Shorter sentences, less clutter, fewer awkward phrases.

Why grammar tools still matter even if you are a strong writer

Even great writers miss stuff. Usually because you are too close to the draft.

A grammar checker helps most with:

fast proofreading when you are on a deadline

catching repeated mistakes you personally make a lot

cleaning up long paragraphs that became messy during editing

making professional writing sound more confident and polished

And yes, it is especially useful for emails and messages where one small mistake can make you look rushed.

Common mistakes people make (and quick examples)

A few errors show up constantly:

their / they’re / there

Their = possession. They’re = they are. There = location.

to / too / two

To = direction or infinitive. Too = also or excessive. Two = the number.

your / you’re

Your = possession. You’re = you are.

its / it’s

Its = possession. It’s = it is.

These feel basic, but they sneak in when you type fast. A proper grammar check catches them immediately.

How to get the best results from this tool

A couple small habits make the output way better:

Paste full paragraphs, not one sentence at a time

Context helps. A lot of grammar and punctuation depends on the sentence before it.

Do one pass for correctness, then one pass for flow

Fix the technical stuff first. Then read for rhythm, tone, and clarity.

Read the corrected version out loud

You will instantly hear any line that still feels off, even if it is technically correct.

Match the dialect to your audience

American vs British vs Australian English changes spelling and certain phrasing conventions.

Grammar checker vs proofreading (they are not the same)

A grammar checker is best at rules. Proofreading is best at meaning.

Use the tool to fix:

grammar, spelling, punctuation, consistency

Then do a quick human review for:

tone, intent, emphasis, whether it sounds like you

That combo is where your writing starts to feel “finished”.

When to run a grammar check (real scenarios)

If you are wondering if it is worth the extra minute, it usually is. Especially for:

job applications, resumes, cover letters

client emails and proposals

essays, assignments, research writing

blog posts and landing pages where credibility matters

social posts where mistakes get screenshotted forever

Even a clean, simple grammar check before sending can save you from awkward follow ups later.
