It does poorly on creative concepts as well.
I attempted to explore the works of Kinoko Nasu/TYPE-MOON through its characters and the relationships across works and it was mostly nonsense. Sure it had some broad relations correct, but it presented a tiny set of meaningful characters and only attempted to touch Fate/Stay-Night and Tsukihime.
Even more damning was that it produced garbled text for a few of the textual representations and often even if the lettering was clean, the grammar was off.
To be fair, disentangling even just the Fate series is nearly impossible even for humans
