Rekognition is a pre-built computer-vision service. It analyzes images and video to detect objects, faces, text, and unsafe content — again, no ML model to build, just an API call.
The tell
Anytime a scenario involves analyzing images or video — facial recognition, object detection, content moderation, text-in-image — that’s Rekognition. Text analysis is Comprehend; building your own model is SageMaker.
