You are about to send an important email. You read it three times. It looks fine. You send it. Five minutes later you notice "their" instead of "there" in the second paragraph. A grammar checker catches what your eyes skip over because your brain auto-corrects familiar text.
What We Check
| Category | Examples | How Common |
|---|---|---|
| Spelling | recieve → receive, occured → occurred | Very common |
| Grammar | Subject-verb agreement, tense consistency | Common |
| Punctuation | Missing commas, incorrect apostrophes | Very common |
| Word choice | affect vs effect, then vs than | Common |
| Sentence structure | Run-on sentences, fragments | Moderate |
| Style | Passive voice, wordiness, redundancy | Moderate |
The Most Common Mistakes
- Its vs it is. "Its" is possessive. "It is" is "it is." No exceptions.
- Your vs you are. "Your" is possessive. "You are" is "you are."
- Their/there/they are. "Their" is possessive. "There" is a place. "They are" is "they are."
- Comma splices. Two complete sentences joined by a comma instead of a period or semicolon.
- Subject-verb agreement. "The list of items are ready" should be "is ready" (the subject is "list," not "items").
