He means to do it?

Hello dears! Could you tell me please what is the difference between the
He is [color=indigo]going to do it
He [color=indigo]means to do it
Sincerely yours

He is going to do it means he really will do it.
He means to do it implies that you is intenting to do it but in the end he might or might not do it.[YSaerTTEW443543]
