Seek by iNaturalist got a lot of very positive press here on HN for some reason, but it's crazy. I assume Seek is why iNaturalist classifies everything as a single species with no possibility of 'unknown' - as Seek views the world, the goal of classifying is to produce a species name, and accuracy isn't a concern.

I have a photo of an elephant seal that Seek informs me is actually a clouded monitor lizard.

I also have two photos of identical plants growing inches apart from each other that Seek informs me are unrelated.
