AI Grammar Checker for Middle School
Diego is a 7th grader who writes at grade level but consistently gets marks deducted for run-on sentences, comma splices, and switching tenses mid-paragraph. He does not always know what these terms mean, let alone how to fix them. The AI Grammar Checker for middle school explains these error types in terms that make sense, a comma splice is two complete thoughts joined with only a comma, which does not hold them together; a run-on sentence is two complete thoughts that have crashed into each other without a proper connector.

Comma splices and run-on sentences: the two most common middle school errors
Comma splices (using only a comma to join two independent clauses) and run-on sentences (joining two independent clauses without any punctuation or conjunction) are the two most frequently marked grammar errors in middle school writing. The AI Grammar Checker identifies both and explains the four options for fixing them: add a coordinating conjunction, replace the comma with a semicolon, make two separate sentences, or subordinate one clause.
Tense consistency: staying in one time frame within a paragraph
Middle school students often begin a paragraph in past tense and drift into present tense mid-paragraph, especially when summarizing a book or describing a historical event. The AI flags the tense shift, identifies the primary tense of the paragraph, and explains the rule: when you are describing events that happened in the past, use past tense throughout the paragraph.
Apostrophe and possessive errors: the most misused punctuation mark
Middle school students frequently confuse possessive apostrophes with plural forms. They also confuse its and its contracted form. The AI Grammar Checker addresses apostrophe errors as a standalone category with clear rule explanations: use an apostrophe to show ownership and in contractions, but do not use an apostrophe to make a noun plural.
