Ask HN: Do people actually pay for small web tools?

Hey all, there's a lot of web stuff and tools I'd love to make that I think would honestly be worth a small subscription ($5/mo maybe). I'm always a bit wary of approaching these ideas though because I feel like nobody would ever pay for small web stuff?

I see a lot of success stories but I don't know how much they can be trusted. Those of you who have built small single-use indie tools, do you find that anybody at all actually subscribes? A lot of the stuff I wanna try involves AI so I'd have to make sure subscription profits offset the cost of providing free demos.
