Why Grammar and Style Matter
Clear, error-free writing is essential for effective communication in today's digital world. Whether you're writing emails, reports, blog posts, academic papers, or social media content, grammar and style mistakes can undermine your credibility and confuse your message.
Studies show that 59% of people would not use a company that had obvious grammar or spelling mistakes in its marketing materials. In professional settings, poor grammar can cost you job opportunities, client trust, and business deals. In academic contexts, it can affect your grades and research credibility.
Good grammar and style aren't just about following rules—they're about clarity, precision, and respect for your readers. A well-written text is easier to understand, more persuasive, and leaves a lasting positive impression. Grammar checkers help you catch mistakes you might miss and learn from your errors to become a better writer.
Common Grammar Mistakes and How to Avoid Them
Subject-Verb Agreement
One of the most common grammar errors is when the subject and verb don't agree in number. For example, "The team are winning" should be "The team is winning" (collective noun takes singular verb in American English). Watch out for tricky subjects like "everyone," "each," and "neither" which are singular despite seeming plural.
Comma Splices and Run-on Sentences
Comma splices occur when two independent clauses are joined with just a comma: "I went to the store, I bought milk." This should be either two sentences, joined with a conjunction ("I went to the store, and I bought milk"), or separated with a semicolon. Run-on sentences lack proper punctuation between clauses entirely.
Misplaced Modifiers
Modifiers should be placed next to the words they modify. "Walking down the street, the trees were beautiful" incorrectly suggests the trees were walking. It should be "Walking down the street, I saw beautiful trees." This mistake can create unintentionally humorous or confusing sentences.
Pronoun-Antecedent Agreement
Pronouns must agree with their antecedents in number and gender. "Each student must bring their book" is incorrect because "each" is singular. It should be "Each student must bring his or her book" or rewrite to "All students must bring their books." Modern usage increasingly accepts singular "they" for gender-neutral contexts.
Apostrophe Misuse
Apostrophes show possession or contractions, not plurals. "The dog's are barking" is wrong—it should be "The dogs are barking" (plural) or "The dog's bark is loud" (possessive). Common errors include "it's" (it is) vs "its" (possessive), and adding apostrophes to decades ("1990's" should be "1990s").

Frequently Asked Questions
How accurate is the grammar checker?
Our grammar checker uses advanced AI algorithms trained on millions of text samples to achieve high accuracy. However, no automated tool is perfect—context and nuance can be challenging. We recommend using the checker as a helpful assistant, not a replacement for human judgment. For critical documents, consider professional proofreading in addition to automated checking.
Can it check grammar in languages other than English?
Currently, the tool focuses on English grammar and style checking. We're working on adding support for other major languages including Spanish, French, German, Italian, and Arabic. Each language has unique grammar rules that require specialized training and algorithms.
Is my text data secure and private?
Absolutely. All grammar checking happens entirely in your browser using JavaScript and AI models loaded locally. Your text never leaves your device or gets sent to our servers. We cannot see, store, or access any of your writing. This makes it safe for confidential documents, personal writing, and sensitive business content.
What types of writing can I check?
The grammar checker works with any type of English text: emails, essays, reports, blog posts, social media content, academic papers, business documents, creative writing, and more. You can adjust style suggestions based on formality level (casual, professional, academic) to match your writing context.
How is this different from spell check in Word or Google Docs?
While basic spell checkers only catch misspelled words, our grammar checker analyzes sentence structure, grammar rules, style, tone, and context. It catches errors that spell checkers miss, like "Your going to the store" (should be "You're"). It also provides style improvements and clarity suggestions beyond simple error detection.
Can it help me learn better grammar?
Yes! Each error comes with an explanation of the grammar rule and why the suggestion is better. Over time, you'll recognize patterns in your mistakes and learn to avoid them. The tool helps you understand grammar rules in context, which is more effective than memorizing abstract rules.
Is there a word limit?
The tool can handle documents of various lengths, from short emails to long essays. For very large documents (over 10,000 words), processing may take a bit longer. If you're checking a book-length manuscript, consider breaking it into chapters for faster processing.

Writing Tips and Best Practices
- Read Your Text Aloud: Before running the grammar checker, read your text aloud. You'll catch awkward phrasing and missing words that automated tools might miss. If it sounds wrong, it probably is.
- Don't Accept Every Suggestion: Grammar checkers aren't perfect. Use your judgment—if a suggestion changes your intended meaning or doesn't fit your style, ignore it. You know your writing best.
- Learn From Your Mistakes: Pay attention to recurring errors. If you keep making the same mistake, take time to learn the grammar rule. This improves your writing skills long-term.
- Consider Your Audience: Adjust formality and style based on who will read your text. Business emails need different language than casual blog posts. The same grammar can be appropriate or inappropriate depending on context.
- Break Up Long Sentences: If a sentence is hard to follow, break it into shorter ones. Clarity is more important than showing off complex grammar. Aim for an average of 15-20 words per sentence.
- Use Active Voice: "The team completed the project" is stronger than "The project was completed by the team." Active voice is clearer, more direct, and more engaging.
- Proofread Multiple Times: Run the grammar checker, make corrections, then read through again. Fresh eyes catch different errors. For important documents, wait a few hours or a day before final proofreading.
