Right now I use them for boiler plate stuff, like writing a text with some parameters and then I polish it

It's actually great for dnd to produce NPC dialogue or names on the fly. We also tried using it to calculate area of effect spells, ie "how many average sized humans in armor with swords could fit in a circle with a diameter of 30ft." We were rolling with it before someone pointed out that it didn't calculate the area of a circle correctly, however it got the rest more or less accurate. So we don't use it for that anymore, and it's funny how what often appears to be the simplest component of a question is the thing it most often gets wrong.
