YouTube RAG Pipeline

Chat with Any YouTube Video

Minimal RAG pipeline transforming YouTube videos into intelligent Q&A systems. Extracts transcripts, builds vector embeddings with Google's embedding-001 model, and indexes with FAISS. Uses LangChain for orchestration and Gemini 1.5 Flash for answer generation. Jupyter-based, Colab-friendly, and Docker-ready.
