PowerToys are a bunch of Windows system utilities that will allow you to maximize your productivity. PowerToys on GitHub recently received a new pull request that introduces a new PowerToy called PowerOCR to perform OCR anywhere on screen by selecting a rectangular region, clicking a word, or right-clicking an image file and selecting PowerOCR. Yes, you will be able grab text from anywhere on your screen. You can see the PowerOCR tool in action in the video below.
Right now, PowerOCR only works on a single screen. Multi-monitor support will be added in future releases.
