Intro to AWS AI Services: Textract, Comprehend, Rekognition

Sharing these demos and compiled docs of AWS AI Services to help you visualize how these services work. These pre-built models will be beneficial for developers with no prior experience to machine learning as the models have been pre-trained. You will only need to call the API with the inputs to get the predicted results.
