Problem

Consultants spent hours per week searching internal knowledge — past deliverables, methodologies, client decks. Most never found what they needed and rebuilt assets from scratch.

Approach

Built an end-to-end RAG pipeline: ingestion with semantic chunking, hybrid search (BM25 + embeddings), reranking, and a thin Next.js chat UI with citations. Added an evaluation harness with 200 reference questions so quality could be tracked over time.

Outcome

Adoption hit 70% of the consulting team within 6 weeks. Reference questions show 85% retrieval accuracy at top-3. Estimated 4-6 hours per consultant per week recovered.
