I think very soon a new model will destroy whatever startups and services are built around document ingestion. As in a model that can take in a pdf page as a image and transcribe it to text with near perfect accuracy.
Extracting plain text isn’t that much of a problem, relatively speaking. It’s interpreting more complex elements like nested lists, tables, side bars, footnotes/endnotes, cross-references, images and diagrams where things get challenging.
I think the Azure Document Intelligence, Google Document AI and Amazon Textract are among the best if not the best services though and they offer these models.
I have not tested Azure Document Intelligence, Google Document AI, but AWS Textract, LLamaparse, Unstructured and Omni made to my shortlist. I have not tested Docling, as I could not install it on my Windows laptop.
