Why the model is not enough
Even the strongest model does not know your contracts, scope, customer history, internal policies and document changes. RAG lets an agent rely on sources, while a knowledge engine prepares knowledge so it can be found and verified.
The required components
A good system needs document ingest, chunking, metadata, vector search, reranking, citations, permissions and evals. If one layer is weak, the agent either misses the right answer or answers without verifiable grounding.
How a WebEdge client should start
Start with one document group: scope lists, contracts, technical guides or support questions. Measure retrieval quality, show sources and only then connect the agent to actions.
