Frequently Asked Questions
- What's the difference between Amazon Comprehend and Amazon Textract?
- Textract extracts text and structure from documents (like PDFs and scanned images) using OCR. Comprehend analyzes text you already have (from Textract, emails, chats, etc.) to find sentiment, entities, key phrases, topics, or classifications. In many workflows, Textract comes first, then Comprehend analyzes the extracted text.
- When should I use Amazon Comprehend?
- Use Comprehend when you need to automatically understand and organize large volumes of text, such as categorizing support tickets, detecting PII in customer messages, extracting entities from reports, summarizing trends with topic modeling, or measuring sentiment from reviews and social posts. It’s a good fit when rules/keywords are too brittle and you want a managed ML-based approach without training your own NLP models.
- How much does Amazon Comprehend cost?
- Pricing is pay-as-you-go and typically depends on how much text you analyze (often measured per unit of characters) and which features you use (for example, sentiment/entity detection vs. custom classification vs. PII detection). Costs also vary by region and whether you run real-time analysis or asynchronous jobs. For accurate estimates, use the AWS Pricing page and the AWS Pricing Calculator with your expected text volume and features.
