Problem

Long YouTube videos are hard to search — viewers want direct answers, not another full watch-through.

Solution

Built a Streamlit chatbot that extracts multilingual YouTube transcripts, embeds them with MiniLM, and retrieves context-grounded answers using a Groq-hosted LLaMA 3.3 70B RAG pipeline.

Tech Stack

  • MiniLM — Lightweight embedding model for transcript chunks.
  • Groq (LLaMA 3.3 70B) — Fast inference for low-latency RAG answers.
  • Streamlit — Quick interactive UI for the chatbot.
