Build an AI Knowledge Base Q&A Bot

RAG-based Q&A bot that ingests our internal documentation (a set of Markdown files) into a vector database and answers employee questions using the OpenAI API with citations pointing to source documents. Deliverables: •⁠ ⁠Document ingestion pipeline for Markdown files into Pinecone or Supabase pgvector •⁠ ⁠Embedding generation using OpenAI text-embedding-3-small •⁠ ⁠Retrieval-augmented generation pipeline returning answers with source citations •⁠ ⁠Simple chat UI built in React or Streamlit •⁠ ⁠Deployment instructions and a short demo video
