You also have the option to complete an "AI Profile", in which you introduce yourself to their model and answer a few questions about yourself. The model will use those info to try to tailor the results to your needs. This profile will be passed on as part of the system prompt in all searches, although Copilot seems to understand it better.

One thing is certain - it won't replace Google. You just can't avoid inaccuracies when dealing with generated text. You will need to go to the results manually to verify them, and sometimes you will need a straight up Google search. It is also a bit slower than Google, since it does need to query an actual search engine and do the summarisation.
