AI Grammar Checker for High School
Chloe is a 10th grader who knows the grammar basics but keeps losing points on academic writing for informality, contractions in essays, a lot instead of a substantial number, really as an intensifier, and passive constructions where her teacher wants active voice. She does not know what academic register means; she just knows her writing comes back marked up. The AI Grammar Checker for high school identifies these register violations specifically, explains what academic writing requires and why, and gives her the formal vocabulary equivalent for each informal choice she has made.

How High school students Use It
Grammar feedback calibrated to the conventions that matter for this audience.
Academic register: identifying and correcting informal writing in formal essays
Academic register is the style of language expected in formal academic writing. High school students who have strong conversational English often produce writing that is grammatically correct but stylistically informal, and informality loses marks even when the ideas are strong. The AI identifies four categories of register violations: contractions, informal vocabulary, inappropriate first-person, and colloquialisms.
Passive voice: when to use it, when to avoid it
High school students are often told to avoid passive voice as a blanket rule, but this is oversimplified. Passive voice is appropriate in scientific writing where the action matters more than who performed it. Passive voice is weak when it obscures who is responsible for an action or when active voice would be stronger and clearer. The AI Grammar Checker distinguishes between these cases.
Subordination and coordination: elevating sentence structure for high school essays
High school writers who have mastered basic sentence structure often rely on coordination (and, but, so) where subordination (because, although, since, which) would produce more sophisticated prose. Subordination indicates the logical relationship between clauses rather than just connecting them. The AI identifies opportunities where subordination would improve clarity and sophistication.
