Grammar Checker
Paste an email, caption, paragraph, essay draft, or message and check it for grammar, spelling, punctuation, and style issues. Review suggestions one by one, then copy a cleaner draft.
Checks up to 6,000 characters. Review every suggestion before using it.
Grammar checking before rewriting
Fix obvious grammar and spelling issues first, then use a sentence rewriter or Fluxkey when the wording, tone, or length still needs work. Grammar suggestions can miss names, product terms, and intentional style choices, so review the final draft yourself.
