I occasionally run into the problem where I need to get some text from an image, document, or website that does not provide for copy and paste. My old tool for pulling text out of screenshots stopped getting updates, so I went looking for new tools and settled on TextSniper (App Store)(website). TextSniper lets you take a screenshot of anything on your screen and pulls out the text, adding it to your clipboard.

It does a good job with the OCR. In the screenshot gallery below, you can see the screenshot and the resulting text pasted into Drafts. I found turning off the "Keep Line Breaks" option works better for me. Regardless, I'm happy to have a new actively developed tool for just this problem.
