[Recording] How I Built an AI-Powered Grocery Expense-Splitting App [8/11/2026]

Splitting grocery bills fairly, without the back-and-forth of screenshots and mental math, is exactly the kind of everyday problem AI is now good enough to solve. In this session, you'll see how one Leland customer built an app that does just that: tracking shared purchases and automatically figuring out who owes what. No coding background required, and that's the point. The speaker will demo the app live, then break down how she actually built it: the tools she used, the choices she made along the way, and where she got stuck. If you've got a small, nagging problem in your own life, this session should leave you with a real sense of how to go build the fix yourself.
