Watch ClauseLens Run

A hybrid-retrieval RAG pipeline for contract intelligence: structural chunking, BM25 + dense fusion, citation-validated answers. Pick a question — this replays a real recorded run of the open-source pipeline.

What you're watching, honestly: these are recorded runs of the real clauselens-rag pipeline against its sample corpus — real queries from the benchmark golden set, real retrieved chunks, real latencies from benchmark_results.json. Nothing here calls a model at page-load; that's the point. Clone the repo and run the same pipeline locally with or without an API key.

Five verticals, one architecture

Each fully specified: architecture, costs, pricing, go-to-market. ClauseLens is built; the rest are queued.
