How Does an AI Grammar Fixer Clean Up Your Writing?
AI Grammar Fixer takes text you've already written — an email, a caption, a comment, a short article — and cleans up grammar, spelling, capitalization, punctuation, and formatting issues without changing what you're trying to say. Paste a draft, choose which correction types to run, pick US or UK English, and review the corrected version before you use it.
This tool doesn't rewrite your tone or restructure your sentences for style — for that, use AI Rewrite Tool. It focuses on the mechanics: the things that make a draft look careless even when the idea behind it is right.
Which Grammar Correction Option Should You Choose?
All five correction types are on by default. Turn off any you don't need — but at least one has to stay selected, or the request won't go through.
| Correction Type | What It Catches | Example Fix |
|---|---|---|
| Grammar | Subject-verb agreement, verb tense, sentence structure | “this tools are useful” → “this tool is useful” |
| Spelling | Misspelled words and typos | “recieve” → “receive” |
| Capitalization | Missing capitals at sentence starts and proper nouns | “i live in london” → “I live in London” |
| Punctuation | Missing or misplaced commas, periods, apostrophes | “its a great tool” → “it's a great tool” |
| Formatting | Spacing, line breaks, and layout cleanup | “hello world” → “hello world” |
What Counts as a Common Grammar Mistake?
| Mistake | Example Before | Example After |
|---|---|---|
| Subject-verb disagreement | “The list of items are long.” | “The list of items is long.” |
| Apostrophe misuse | “Its a great tool for writer's.” | “It's a great tool for writers.” |
| Comma splice | “I finished the draft, I sent it.” | “I finished the draft, so I sent it.” |
| Homophone mix-up | “Your going to love this.” | “You're going to love this.” |
| Run-on sentence | “The report was long it took an hour to read.” | “The report was long, so it took an hour to read.” |
These are exactly the kinds of issues Grammar, Spelling, and Punctuation catch together.

What Do You Need To Add Before Fixing Grammar?
Paste the draft into the text box — up to 6,000 characters. Choose which of the five correction types to run (all are on by default), pick US or UK English, and decide whether to keep Preserve formatting and Show corrections switched on. Add a custom instruction if there's something specific to keep, like a brand term or a name's exact spelling.
Tip: at least one correction type must stay selected — unchecking every box returns an error instead of a result.
How Does AI Grammar Fixer Work?
Anything up to 6,000 characters — an email, caption, comment, or short article.
Pick which of the five checks to run and select US or UK English.
Check what changed before using the result anywhere that matters.
Note: this tool doesn't rewrite tone or sentence style — that's what AI Rewrite Tool is for. It's designed to preserve your original meaning while fixing the mechanics you've selected, so it's still worth a quick read before you publish.
How Do You See What Changed In Your Corrected Text?
The Compare action shows a line-by-line breakdown of the original text against the corrected version, labeling each line Removed, Added, Changed, or Same, with word-level highlighting on the specific words that changed. It's the actual before-and-after, not a summary — useful for confirming a correction only touched what you asked it to.
Should You Turn Off Formatting Cleanup or Corrections Highlighting?
Preserve formatting keeps line breaks and spacing you set on purpose — like a list layout — instead of collapsing everything into one block. Show corrections highlights exactly what changed inline; turning it off gives you a plain, clean version with no markup. Turn Preserve formatting off if your paste has messy line breaks you want cleaned up. Turn Show corrections off if you just want the final text, not a marked-up view of the edit.
US English vs UK English: Which Should You Choose?
| Aspect | US English | UK English |
|---|---|---|
| Spelling | color, organize, center | colour, organise, centre |
| Punctuation with quotes | Comma/period usually inside quotes | Comma/period often placed outside quotes |
| Collective nouns | “The team is…” (singular) | “The team are…” (often plural) |
Pick based on where your reader is, not where you are.
What Should You Check Before Publishing Corrected Text?
- Does the meaning still match what you meant to say?
- Are names, numbers, and quoted material untouched?
- Does the English variant match your audience?
- Did you check Compare for anything unexpected?
- Would you publish this version as your own words?
Frequently Asked Questions
Is AI Grammar Fixer free to use?
Yes, free on ToolsLuv, no signup, no limit.
Do I need an account to use it?
No.
What does an AI grammar checker actually fix?
Grammar, spelling, capitalization, punctuation, and formatting issues in text you paste in, based on which correction types you leave selected.
How do you fix grammar mistakes in a paragraph?
Paste it in, keep the correction types you want checked, and review the corrected version before using it.
How can AI correct grammar without changing your meaning?
The correction is designed to preserve your original meaning while fixing mechanics; use Compare to confirm nothing changed beyond that.
How do you fix spelling mistakes automatically?
Keep the Spelling checkbox selected; it's on by default alongside Grammar, Capitalization, Punctuation, and Formatting.
How do you fix punctuation mistakes in a sentence?
Keep Punctuation selected and paste the sentence; missing commas, apostrophes, and end punctuation are corrected along with any other selected types.
How does the AI decide what to correct?
It uses whichever correction types you leave checked, plus your English variant and any custom instructions.
What happens if I uncheck every correction type?
The request is rejected. At least one correction type has to stay selected.
Why does a correction sometimes look like it barely changed anything?
If the draft only had one or two small issues, a smaller, targeted fix is expected. It's not meant to rewrite clean sentences.
Is my pasted text stored?
No account is created; the request generates your correction and isn't kept as reusable data afterward.
Does this tool use AI?
Yes, requests go to a server-side AI endpoint; this isn't a local, browser-only tool.
Can I export the corrected text?
Yes, Copy or TXT.
What do History and Saved do?
Both are stored locally in your browser, not on a server.
Does it work on mobile?
Yes.
Should I use a corrected version exactly as-is?
Check it against the checklist on this page first, especially names, numbers, and quoted material.
What's a common mistake when using a grammar fixer?
Turning off every correction type except one, which leaves the other issues in your draft untouched.
Does fixing grammar improve SEO by itself?
Not directly. Clean writing helps readers, but rankings depend on far more than grammar alone.
The correction missed an issue I expected it to fix — what now?
Check that the right correction type is still selected; each type only fixes its own category of issue.
The result changed more than I expected — what should I change?
Add a custom instruction asking it to keep your wording, or turn off Formatting if only spacing/structure should stay untouched.
