Azure Doc Intel is good. It creates a semantic representation (is json) of the doc. The schema is useful with page, paragraph, table, etc objects. The bounding-box for each element is also useful. It flails with images, only giving you the bounding-box of where the image exists. It’s up to you to extract any images separately then figure out how to correlate. Overall I think it’s useful rather than rolling your own (at least for small scale).
