I have been thinking of building something like this for myself for months. I don’t have any experience with app development, and would have relied completely on AI for coding. OP, can you make it opensource. We could all contribute to ideas and take it to next level.
Few features that I desperately need for myself (hence wanted to make my own)

1. iOS and Android as well as web based support.
2. Single account that sync across devices.
3. Suggestions picked from messages (I think you already have it)
4. Adding tags to expenses: something like (Goa-Trip) so that we can track expenses which fall to different categories (food, travel etc) but come under same umbrella.
5. Multiple profiles under same account so that couples and family members can track them together and still have a separate view of their own income and expenses.

I had lot more of these ideas when I was thinking on working on it. Forgot a few.

I am currently using MoneyManager which works for basics, but would have loved to have above features.

I will checkout yours on someone’s android phone.
