Also at least a dozen different fungi, where being able to filter by shape and colour would be a nice starting point.
Merlin appears to be mobile-only spyware.
BugFinder is an overly crude tool that only works for North America. (Though it did tell me one of my beetles looks like a Soldier Beetle.)
https://uk.whatbird.com is the least worst bird identifier I've found - it's often frustratingly slow and not easy to use, and its example images can differ from what an image search returns, (so potential matches need to be checked twice).
For example, Wolfram's answer to one image (containing a hoverfly) is that it's an "Africanized bee" - despite that only existing in South America and southern US, (not to mention the image quite clearly being a fly and not a bee).
Google's answer for the same image is a Short-tailed Blue, which at least gets the correct family of the butterfly, if not the right genus (it's actually a Holly Blue).
(Side-note: If I didn't know they were both wrong, the fact that the Short-tailed Blue isn't found on the American content would be evidence that one of them was incorrect.)
Neither Wolfram nor Google gave any hint of recognising more than one thing in the image. Neither of them get me closer to identifying the pink-flowered bush the two insects are on.
My ideal solution would be an open source Lightroom plugin that did image recognition for the basics, then asked questions for the bits it's not certain about, and worked fully offline.
What I expect I'm going to have to do instead is spend a significant amount of money on a stack of books that will then become a constant source of getting in my way.
If I could tell them it was found in Pembrokeshire woodland they'd know those answers were wrong.
But I can't, so I'm back to guessing unknown attributes and scrolling through an endless haze of mature pink flowers trying to figure out if any of them match what this bastard thing might become.

Thanks. :)
Wolfram's Image thing said wheatear, which is a candidate and a regular image search for wheatear agrees (and matches closer than any of the other six, despite mostly all being chats), as does Wikipedia.
Hooray for simple victories! (dance)
Fun fact: wheatears are not named after cereal grain, but a corruption of the descriptive term: white arse.
