The standout strengths of Amazon Comprehend are: (1) Minimal setup overhead - the pre-built models for English text are good enough for most general-purpose work, and the simple API meant we could fold NLP into existing pipelines within days rather than weeks. (2) Custom classification and custom entity recognition for domain-specific needs - the training workflow is reasonably accessible to engineers who aren't ML specialists, which lowered the barrier for us to extend the service rather than treating it as a black box. (3) Smooth integration with the rest of the AWS stack (S3 for batch jobs, Lambda for inline processing), which is one of the main reasons we stayed with it rather than switching. (4) Pay-per-use pricing made it easy to start small and scale once we'd validated the output quality for our use cases.
