Build a Reliable RAG Chatbot for Your PDF Documents

Do you need an AI assistant that answers questions directly from your documents?


I will build a custom RAG (Retrieval-Augmented Generation) chatbot that allows users to upload PDF files and receive accurate, document-grounded answers.


Unlike generic AI chatbots, this solution retrieves relevant content from your documents before generating responses, reducing hallucinations and improving reliability.


What You Will Get

  • PDF ingestion and text processing
  • Intelligent document chunking
  • Vector search (FAISS or Chroma)
  • RAG-based question answering
  • Clean web interface (Gradio or FastAPI)
  • Source code included
