I build a knowledge assistant that answers from your approved documents and shows the source behind each answer. The work covers document ingestion, passage and metadata design, retrieval, source-linked answers, and tests for wrong-source and no-answer cases. I shape it around the material your team uses, such as product specifications, policies, procedures, or support documents. You receive a working assistant for an agreed set of sources, evaluation examples, deployment notes, and a handoff. We define access controls, document updates, and integrations before pricing.
