Comprehend is a natural-language-processing service. It reads text and extracts meaning — sentiment, key phrases, entities, language — through a simple API, with no ML model to build.
The tell
When a scenario needs to analyze text — detect sentiment in reviews, pull entities from documents, redact PII from text — that’s Comprehend. It’s a pre-built AI service: you call the API, you don’t train a model (that’s SageMaker).
