Shared Expenses

So we've been having challenges with our expenses over the years. We've tried using YNAB, but it's very difficult if you don't stay on top of it.

We live with my father and need to split expenses with him. For example, he covers 70% of the mortgage and we cover 30%. There are the groceries, and then there are things for our two boys that they pay for personally. Other expenses come out of their school funds. So it's a real mess and can take forever to do.

I'm thinking about how programming and using AI can make this more effective and efficient.
