Ever heard footsteps behind you with no one there? Can't find your keys again? Had an unexpectedly great day for no reason?

Yokai Did It! lets you describe any moment from your day, and our AI confidently matches it to the yokai responsible, drawing on traditional lore about creatures like the mischievous river-dwelling Kappa, the shapeshifting Kitsune fox spirit, the dream-eating Baku, and 27 more.
