Startup Idea: Smart Personal Finance Assistant

Startup idea to develop a smart personal assistant software that connects with user's bank account, tracks and analyzes their expenses, provides detailed reporting, and helps in budget planning.

I would like to have a smart personal assistant, that would help me track my expenses, for example could connect to my bank account and tell me how much on average I spent on groceries every month last year and by how many percent the spending's increased. I would like the assistant to make charts for me and help me plan my budget based on what she knows about me.
