I fed it with sentences from the Bulwer Lytonn contest with some success https://twitter.com/avi_eisen/status/1284924171215044608?s=2...

I actually submitted two of the sentences to the contest (it's 2 and 4 in the tweet I said 2 and 4 seemed winnable).

Watch the Twitter thread - I'll be adding stuff to it, going to check writingprompts now.
