The problem I have with the AI mastering is it seems to be a bit clumsy with making the master fit the song. A lot of these tools just have simple buttons like "low, medium high", and seem to default to really squashing the dynamics to achieve maximum loudness. I have worked with both human mastering engineers and AI mastering, and I would say a decent human mastering engineer is noticeably better at feeling out the songs and finding the right balance.
To your question though, it's a chatbot so tell it you want your track to sound like eg Polo and Pan, it'll look for ways to enhance it in their style rather than a simple small/medium/large knob. It'll load one of the built-in mastering chains and tweak the settings on those, or if you have a preference, you can tell it that too.
