I have an app called 'creative writing' I'm pretty sure that has a few things. The generators for situation and character can have their uses, but it doesn't really do prompts. I've used a few sites and generators, but I have enough ideas without finding more usually. XD

I know quote a few prompt type things that I learned in some creative writing classes like using random pictures, or writing character information on slips of paper and having the whole class pick at random. Basically a homemade generator, just with people you know making the prompts. Usually I just let prompts come to me rather than look for them.

I may look into this Reedsy thing though.
