Amazon Textract is a machine learning service that automatically extracts text, handwriting, and data from any document or image. Textract now provides you the flexibility to specify the data you need to extract from documents using the new Queries features within Analyze Document API. You do not need to know the structure of the data in the document (table, form, implied field, nested data) or worry about variations across document versions and formats. Queries leverages a combination of visual, spatial, and language cues to extract the information you seek with high accuracy.
