Saving money doesn't really need an AI, there really aren't many ways to cut budgets down short of paying attention to the most obvious spending problems (Too much housing, too much vehicle, too much food (especially eating out), and too much entertainment(too many subscription platforms))
It's usually a far better investment of time to improve your earning power (upskill, change jobs, add hours, etc.)
Cutting $40 per month from your budget by not going to the movies every week just isn't going to have the impact you need in your life.
