went to look at their github issues tracker and this one made me cackle. Poe status undetermined but it delighted me so much:
https://github.com/xai-org/grok-prompts/issues/16

I have a Kobo Sage and it's nice, I exclusively sideload epubs/kepubs onto it. I have installed KOreader in case I want to read PDFs.
