When AI makes a decision based on a document, you need more than an answer — you need proof. Ninjadoc returns exact source coordinates for every field, making every agent-driven extraction auditable by default.
Call Ninjadoc from any agent framework. Structured JSON answers with citation URLs that travel with your data into every downstream system.
Agents hallucinate. Ninjadoc doesn't. Every field comes with page number and bounding box coordinates pointing to the exact location it was drawn from — text, image, checkbox, or signature.
Every extracted field comes with a citation URL linking directly to its source location in the document. When an auditor asks where the number came from, you have a link — not just a claim.
