I sometimes have situations where i'm trying to find the origin of an image.
Google has an 'exact match' feature that allows you to find exact matches of images.
Tineye does this by default but they're better at it and actually are able to find 'pretty much the same picture, but modified in some way' kind of 'exact images'.
While Kagi does indeed show exact matches here, I can't filter on only those.
