What personal finance tools have you built with Claude?

I'd love to hear about the personal finance and budgeting tools people have built by connecting the free Plaid API to Claude. What features have you added that you're finding really useful? I've put together a local page that I can refresh anytime that shows my expenses, categories, etc - but I'm trying to brainstorm better/more useful ways to use the raw data I have. I'm looking for ideas that'll spark inspiration!
