Ask HN: Is anyone using LLM based document processing in production?

Every extracted field comes with a precise citation back to the source document (page + snippet + bounding box + confidence score) so reviewers can verify where each value came from.

Hallucinations get flagged automatically because there's no supporting text in the source.

The goal is to make HITL fast and not have reviewers read through the whole document.

"Human in the loop doesn't help because the human would just have to read the document themselves to ensure accuracy, defeating the point of the automation."

They're doing it manually without it. Semi-auto beats manual readily. There's still checks like submission of the number to grab the details of the individuals involved, and if the names, vehicle type, etc don't match, that automatically flags that something's off.

That’s what we’ve been using for document extraction where accuracy needs precision (capital markets documents, medical assessments). We had a go at pure LLM with medical documents but the output was poor and felt like it would take substantial investment to create something more robust.
