What is an AI Grammar Checker?
An AI Grammar Checker analyzes your text for grammar mistakes, spelling errors, and punctuation issues—then fixes them with explanations so you actually learn. Choose strict, balanced, or minimal checking based on what you're writing. 2000 words per check, completely free, no account required.
Unlike basic spell-checkers that only catch typos, this tool understands context and catches subtle grammar errors that change meaning. Each correction includes the error category and a one-sentence explanation of the grammar rule, turning every check into a learning opportunity.
