# 🔬 RAG Transparency Lab

**See inside every step of a RAG pipeline — applied to scientific papers.**

Upload any scientific PDF, ask a question, and watch the entire pipeline unfold — chunking strategies, hybrid retrieval scores, reranking decisions, filtering logic, and the exact prompt sent to the LLM.

Built by **Zalina Dezhina, PhD** — AI Evaluation Scientist
