Refract

hybrid RAG, visualized

BM25 (lexical) and HNSW (vector) retrieval run in parallel and get fused with Reciprocal Rank Fusion, with multi-hop agentic decomposition for cross-topic questions — and instead of hiding all of that behind a spinner, this shows the pipeline as it runs.

Pipeline

Ask a question and watch the retrieval pipeline run in real time.

Query → decompose → BM25 + HNSW retrieval → RRF fusion → synthesis

Answer

The cited, synthesized answer will appear here once retrieval finishes.
