USAGE
The contraction aren't is used in standard English to mean 'am not' in questions, as in I'm right, aren't I? The more logical form amn't is now non-standard and restricted to Scottish, Irish, and dialect use. Outside questions, it is incorrect to use aren't to mean 'am not' （for example, I aren't going is clearly wrong）.
