[{"role": "user", "content": "I'm trying to learn some essential phrases, and 'I'm not so sure' is one of them. Could you please help me translate it into Italian?"}, {"role": "assistant", "content": "The translation of 'I'm not so sure' in Italian is 'Io non ne sono cos\u00ec sicuro!' If you want to use a more informal tone, you can also say 'Non ne sono cos\u00ec sicuro.' Don't forget to adjust the sentence according to your gender, if you're a female the correct sentence will be 'Io non ne sono cos\u00ec sicura!' or 'Non ne sono cos\u00ec sicura.'"}]
