Grammar Checker Free — No Signup, No Word Limit

Last updated: 2026-03-11

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.

The Most Common Mistakes

  1. Its vs it is. "Its" is possessive. "It is" is "it is." No exceptions.
  2. Your vs you are. "Your" is possessive. "You are" is "you are."
  3. Their/there/they are. "Their" is possessive. "There" is a place. "They are" is "they are."
  4. Comma splices. Two complete sentences joined by a comma instead of a period or semicolon.
  5. Subject-verb agreement. "The list of items are ready" should be "is ready" (the subject is "list," not "items").
