I can be more precise if you don't want to rely on context clues and want to take a pedantically literal interpretation of "all sorts of people". The people who currently pay money for these kinds of apps have pretty good odds of just making their own in the future provided AI agents stick around and are comparably priced to now. It's already the case where about 30 minutes of effort and maybe an hour of waiting will get you something that likely matches your workflow better than a paid option, and if it's being created by an under-utilized AI subscription, the cost is essentially free.
