Document intelligence represents one of the most impactful applications of AI agents in enterprise environments. Unlike simple document classification or keyword extraction, true document intelligence requires agents that can read deeply, extract novel ideas, synthesize across sources, and deliver insights tailored to different stakeholder needs.
This case study examines how we built a multi-agent system for a research organization analyzing hundreds of technical documents monthly.
The Challenge
The client needed to:
- Analyze 200+ technical documents per month across multiple domains
- Extract novel ideas and identify emerging patterns
- Synthesize findings across related documents
- Deliver customized summaries to different teams (research, legal, executive)
- Maintain citation accuracy and provenance tracking
Traditional approaches failed because:
- Manual analysis was too slow (20-30 min per document)
- Simple keyword extraction missed nuanced insights
- Single-perspective summaries didn't serve all stakeholders
- No systematic way to connect ideas across documents
Our Multi-Agent Architecture
We designed a coordinated system of specialized agents:
Document Parser Agent: Extracts structure, figures, tables, and references using multi-modal processing.
Concept Extraction Agent: Identifies key ideas, technical claims, and methodological approaches using domain-tuned models.
Novelty Assessment Agent: Compares extracted concepts against knowledge base to identify genuinely new ideas.
Synthesis Agent: Identifies patterns, contradictions, and connections across multiple documents.
Stakeholder Adapter Agent: Reformats analysis for different audiences (researchers want methodology, executives want strategic implications).
Key Technical Decisions
RAG Pipeline: We implemented a hybrid vector + graph database approach for semantic and relationship-based retrieval.
Multi-Modal Processing: Google ADK handled documents with complex figures and mathematical notation.
Quality Assurance: Citation tracking and fact-checking agents validated extracted claims against source material.
Results
- 85% reduction in analysis time (from 25 min to 3 min per document)
- 40% increase in novel insights identified (agents found patterns humans missed)
- 95% citation accuracy (verified by legal team)
- Stakeholder satisfaction scores increased from 6.2 to 8.9/10

Lessons Learned
Document intelligence requires more than NLP—it requires agents that understand stakeholder mental models, maintain context across hundreds of pages, and synthesize insights that serve multiple perspectives simultaneously.
