Below the tool, you'll find everything else: what this checker actually catches, who needs it most, and where it falls short compared to premium options.
What Does This Grammar Checker Do?
It finds common writing errors. Simple as that.
The tool scans your text against a set of grammar rules — subject-verb agreement, punctuation placement, spelling dictionary, and basic sentence structure. When it finds a violation, it highlights the problem and suggests a correction.
What it catches reliably:
- Spelling errors: "recieve" → "receive," "seperate" → "separate"
- Punctuation mistakes: missing periods, extra commas, "its" vs. "it's"
- Subject-verb agreement: "The list of items are" → "The list of items is"
- Tense consistency: switching between past and present
- Homophone confusion: "your/you're," "there/their/they're," "affect/effect"
- Double words: "the the," "and and," "of of"
Types of Errors You'll Catch
Spelling mistakes
The dictionary includes standard American English. Proper names may show as false positives.
Punctuation errors
Missing commas, run-on sentences, apostrophe misuse — all flagged.
Grammar rule violations
Subject-verb agreement, pronoun agreement, sentence fragments.
What it won't catch
Context-dependent errors, style issues, passive voice overuse. Those require human judgment.
Who Benefits Most From a Grammar Checker?
Students writing essays
Professors deduct points for spelling and grammar. Run your draft through before submission. It catches the obvious errors that cost you a letter grade.
Non-native English speakers
English has weird rules. A grammar checker gives you real-time feedback. You'll learn from your mistakes instead of repeating them.
Bloggers and content creators
Your readers judge credibility by your writing. A typo makes people click away. Run posts through before publishing.
Professionals writing emails
One typo looks sloppy. Two make you look careless. Paste important emails before sending. Takes ten seconds.
Limitations vs. Paid Grammar Checkers
Let's be straight with you.
Grammarly Premium catches about 85% of all errors in its free tier and closer to 95% in paid. It also offers tone detection, genre-specific suggestions, and a plagiarism checker. Cost: $30/month.
Linkrify1 free grammar checker catches 70-80% of common errors. It won't suggest better word choices. It won't tell you your email sounds too aggressive. It won't check for plagiarism.
So why use ours? Because it's free. No subscription. No credit card. No "start your 7-day trial" bait and switch. Use it 100 times a day. We don't care.
When should you upgrade? For academic theses, grant proposals, job applications — any document where perfection matters. For everyday writing, our free grammar checker online works fine.
Tips for Getting the Most Out of a Grammar Checker
Read the suggestion before clicking
The tool flags "their" as potentially wrong. But maybe you actually meant "their." Context matters. You know what you meant.
Run multiple drafts
Fix the errors. Paste again. Sometimes fixing one mistake creates another. A second pass catches those.
Learn from your mistakes
Notice you always misspell "accommodation"? Write it down. The goal is to stop making the same errors.
Don't ignore flagged proper nouns
The checker will flag "Linkrify" as misspelled. It's not. Same for your name and industry jargon.
Frequently Asked Questions
Is this grammar checker really free?
Yes. No hidden fees. No word limits that force an upgrade. No "pro" version. Use it as much as you want.
How many words can I check at once?
Up to 2,000 words per check. That's about 4 pages of single-spaced text. Longer than that? Split your document into sections.
Does it check punctuation and spelling or just grammar?
All three. Spelling errors, punctuation mistakes, and grammar violations. The tool highlights everything it finds.
How accurate is this free grammar checker?
Expect 70-80% accuracy for common errors. For high-stakes documents, pay for Grammarly or hire a human proofreader.
Do you store the text I paste?
No. Your text stays in memory only during the check, then gets deleted. We don't save it or train AI on it.
Can I use this for languages other than English?
No. This tool checks American English only. UK variations like "colour" will flag as errors.
How is this different from Microsoft Word's spell check?
Word catches spelling and basic grammar. Our tool catches more: subject-verb agreement, tense consistency, homophone confusion.
Does this work on mobile?
Yes. The text box works on any device with a browser. Paste, check, copy back. Same process as desktop.
Can teachers use this to check student work?
Yes. Paste student submissions. Get highlighted errors. No student accounts needed. No data storage.
What's the difference between this and the plagiarism checker?
The grammar checker fixes your writing. The plagiarism checker checks if your writing exists elsewhere. Two different tools.
