Which bookkeeping task would you hand to your AI first?

I built Nani so the AI you already pay for can do the routine bookkeeping, with you approving the changes. I'm curious where people would start. Categorizing transactions? Answering "what did I spend on software this year?" Getting year-end records ready for the CPA? Something else entirely?

Tell me what eats your time, and I'll use the answers to decide what Nani gets better at next.
