Planning pain points

My boyfriend is likely going to propose this summer, and I am so excited but already stressed about wedding planning. I work in tech so I want to build an AI agent that helps me plan now so I can be ready when the time comes. What was the most ANNOYING part of planning a wedding?? (mainly from an admin perspective - unfortunately can’t address difficult bridesmaids or in laws) I want to try and set up an agent that can handle this for me.
