@aeva i just asked people with access to it to ask a very specific question (klapaucius' request for a six-lines poem from kandel's translation of lem's cyberiad), and it failed spectacularly: https://circumstances.run/@mawhrin/109457122462577129
(i was mostly interested if the engine was fed the text of the story, but the result was interesting in itself; none of the returned results were six lines long)
