Show HN: I built a simple personal finance tool

I don't know what tech stack you used, but very well done! :) especially considering the time I suppose you had to built such app.

I would make the bars that represent the months clearer by labeling the months (I just tried the demo).

I'm not sure what do you need in order to just ask for people its bank statements (even if it's not stored). I would check into that. I think people need more actionable advice (less generic, less "you need to improve on this) than just seeing the same tips over and over again, but this might be hard to implement depending on what we are talking about.

There are some good cheap recipes on the internet, but they might be hard to find sometimes, for instance (despite the promise of making good and affordable recipes is very easy to find, that's other thing). In some countries, it might be hard to know who is really offering some of the cheapest services like insurance, for instance, because this is also kinda hard to simulate for some situations. In other situations, I also don't see how a notification that "you should spend less on parties" really goes beneath the surface of any problem whatsoever. Imagine you are dealing with an alcoholic. That not only doesn't work, but its also probably just annoying.

Tracking tools are cool because people need to track expenses anyway, and it's much easier to do it digitally, than to do it with a pen and paper (even if there are a ton of apps out there, with the right marketing and a little bit of luck, you can have some market share and that's great). AI generated advices... Each case is a case. Each person is a person. It's a ton of work, and it needs to be done carefully. If you are aware of all of this, and want to test in some situations, I will say go for it. If you want something very superficial and generic like some popular magazines and websites do nowadays, I would not invest much time on it.
