Snap&Read Universal reads both accessible and inaccessible text aloud from websites, images, photographs, PDFs, and more. Snap&Read also adjusts complex text to be more readable, and can translate text into over 100 languages. You can even take a picture and have the text within that picture read aloud. Snap&Read has both an App (for reading aloud, translating, simplifying, and annotating PDFs and Images) and a Safari extension (for reading, simplifying, and translating websites). If difficult vocabulary is too challenging, Snap&Read can dynamically level the text. Essentially, Snap&Read will pick out the difficult words/phrases and swap them out for easier to comprehend vocabulary/phrases. To see the original word, just tap on it to toggle between the original word and the simplified word. THIS... "The Time Traveller was expounding a recondite matter to us." BECOMES... "The Time Traveller was explaining a unknown matter to us." Finally, if you have paper, magazine, book, etc... you can use the Camera feature to take a picture and read. If you’re on the go and don’t want to bring your books… you can save the images to your picture library and access them all later right from the Snap&Read App even if you have no internet connection.
