I made a Pleco Screen Reader shortcut that I'm happy to share here. It's designed to be triggered from Control Center. You pull up the content you want to OCR, hit the button in Control Center, and the shortcut will take a screenshot (which is then discarded), get the text from the screenshot, and open it in the Pleco clipboard reader. It will then automatically put a title on the clipboard (the name of the app the screenshot came from and a timestamp) so if you save the text to a file you can just paste in the title.
Pleco obviously has OCR capabilities, but this is a fast alternative.
