Can I get a patent for an innovative financial advisory software?

I am developing a great online personal finance platform that provides comprehensive financial monitoring and planning, including insurance, debt, risk assessments, accounting, and projective advice on investments. The concept is based around an innovative use of AI/expert systems with the goal of providing financial advice similar to what a finance professional would provide. The project requires significant development effort, and I would like to know how to best protect my work. Can I get a patent for the software?
