    Introducing **ZooSign Reader**, an innovative application designed to enhance your zoo experience! **ZooSign Reader** allows users to effortlessly upload images of zoo informational signs and receive detailed information about the species mentioned on those signs.

    With **ZooSign Reader**, you no longer need to spend time searching for information about a particular animal or bird species while visiting the zoo. Simply capture an image of the sign using your smartphone camera, or choose an existing image from your gallery, and let **ZooSign Reader** do the rest.

    Using cutting-edge image recognition and natural language processing technologies, **ZooSign Reader** quickly analyzes the uploaded image and extracts the text containing the scientific name. The app then searches the IUCN Redlist's extensive database, which includes a wide range of animals, birds, and reptiles found in zoos worldwide.
