[{"role": "user", "content": "I'm trying to learn some common phrases in Italian and I'm stuck on the sentence 'You know it.' Can you help me translate it?"}, {"role": "assistant", "content": "The translation of 'You know it' in Italian is 'La sapete.' If you want to use the informal form, you can say 'Lo sai' (for one person you're familiar with) or 'Lo sapete' (for multiple people you're familiar with). However, 'La sapete' is a more formal way to express this phrase."}]
