How Courdx Works
Most RAG systems do simple vector search: query in, documents out, hope for the best.
Courdx uses five layers of intelligence to deliver accurate, verifiable answers.

Deep Dive
Three Pillars of Intelligent RAG
Each pillar addresses a fundamental limitation of basic RAG systems.
Intelligent Retrieval
We Don't Just Search. We Understand.
Five layers of intelligence between your question and your answer. Query decomposition, HyDE, multi-strategy retrieval, reranking, and corrective RAG.
Knowledge Graph
See the Connections Others Miss
Automatic entity and relationship extraction. Community detection reveals hidden patterns. Answer questions vector search can't.
Trust & Citations
Every Fact. Every Source. Verified.
Sentence-level citations, not "somewhere in this document." AI guardrails prevent hallucinations. Full audit trail for compliance.
The Complete Journey
From question to trustworthy answer in five intelligent steps.
Your Question
Natural language query from your team
Intelligent Query Processing
Query Decomposition → HyDE → Expansion → Routing
- Complex questions broken into answerable parts
- Generate what the perfect answer looks like
- Expand acronyms and synonyms
- Route to best retrieval strategy
Multi-Strategy Retrieval
Vector Search + Knowledge Graph + Keyword (Hybrid)
- Semantic similarity via embeddings
- Graph traversal for relationships
- Keyword matching for precision
- Reciprocal Rank Fusion combines results
Intelligent Validation
Relevance Grading → Reranking → Corrective Actions
- Score every result for relevance
- Cross-encoder reranking
- Low confidence? Refine and retry
- Fall back to web search if needed
Trustworthy Response
Answer + Citations + Confidence Score + Guardrails
- Synthesize answer from validated sources
- Cite every fact to exact sentence
- Show confidence score
- Apply output guardrails
