Guardoc described a pipeline that combines Textract, patient-scoped retrieval, Amazon Nova filtering and multimodal reasoning over original PDF pages. The company reports processing more than one million documents on peak days while retaining page-level provenance.
Why it matters: The architecture demonstrates a useful cost-and-risk cascade: inexpensive structured extraction first, then more capable multimodal reasoning only for ambiguous material.
