What does a grammar checker do?

A grammar checker reads your writing and flags errors such as subject-verb disagreement, misplaced commas, spelling mistakes and confusing sentence structure. Good checkers also explain why something is wrong, so you learn as you go.

Our Grammar Checker will highlight issues inline, suggest corrections you can accept with one click, and work across many languages, consistent with the rest of HumanizeAI.
