Answer: Use Document AI, which adds form parsing and entity extraction to the OCR
Google's Vision documentation says that for text in scanned documents you should try Document AI, which pairs OCR with structured form parsing and entity extraction. Every Vision route still returns words and where they sit: document text detection only copes with denser pages and handwriting, higher resolution improves reading accuracy rather than output shape, and object localization returns unlabelled boxes.
