Ain't – "Ain’t" is always wrong, whether it is used to mean "to be" or "to have." The use of “ain’t I?” is nonstandard. “Amn’t I?” is also nonstandard English; “aren’t I?” is standard English. Despite the use of “ain’t I?” and “amn’t I?” in some dialects, “the correct standard singular form is the plural form aren’t: I’m right, aren’t I?”
