Are you referring to Mouser's Universal Key?  It only works with Mouser's software.  (Clipboard Help+Spell, FARR, Screenshot Captor, etc.)  WinRar is another application from another company. 

Edit:  You can get the licence by doing a donation.  See here https://www.donationcoder.com/Donate/index.html  Remember though, it's only for the apps here https://www.donationcoder.com/Software/Mouser/index.html not any app from any website.

Similar to Tomos' idea--or maybe not so similar...   An app that will take a folder full of wallpaper images that I downloaded from reddit and other location, and do a reverse image search, then rename the image with the most-likely description.   Sometimes I'm proactive enough to actually name the image as I save it to my computer, but often the names are like "qwssdfde.jpg."  Presumably this would require an algorhythm to look at the different possible names and "guess" the best one...
