## Why This Matters

Knowledge workers **spend 2.5 hours daily** searching for information buried in documents. Enterprise RAG eliminates that friction—upload your contracts, research papers, or financial reports, ask questions in plain English, and get precise answers with page citations in under 5 seconds.
