Free Optical Character Recognition (OCR) Apps

Apps like Microsoft Lens and Google Keep are revolutionizing how we interact with text through their use of optical character recognition (OCR) technology. This powerful tool can recognize letters in photographs, transforming images into electronic text that can be easily read and manipulated. By integrating OCR with text-to-speech technology, these apps enable users to listen to written content, making information more accessible than ever. In this article, we’ll explore how to turn printed text into spoken words to enhance your reading experience.

The benefits of OCR:

  • Converts an image of text into digital text that can be read aloud by text-to-speech technology or screen readers

Using Microsoft Lens or Google Keep, you can take a picture of a printed handout or a book page and have it read aloud to you.

For this tutorial, download the free Microsoft Lens app and the free Google Keep app on your mobile device. Both are available to download on iOS and Android devices. You may be prompted to use your login information from your free Microsoft account and free Google account.

  2. In the camera view, swipe the bottom of the screen to select Document.
  3. Press the Circle button to take a photograph of a page of typed text.
