Why Do People Use Bank Statement Generators?

I’ve been hearing more and more about people using bank statement generators, and it got me wondering—what are the real reasons behind this trend? Are there legitimate uses for these tools, or is it mostly just for sketchy stuff? I'm curious about the practical side of it. For example, could someone use it for budgeting or mock-up purposes? I’d like to hear from people who have seen or used one, just to understand the full picture and not jump to conclusions. What’s your take on this?
