RAG Chatbot for PDFs: Ask Questions, Get Answers

# Chatbot for answering questions from PDFs using RAG, Ollama, and Qdrant

This automation enables a private chatbot that answers questions based on uploaded PDF documents. Built with RAG (Retrieval-Augmented Generation), it uses local Ollama and Qdrant services to deliver accurate semantic search without exposing data to public APIs. Ideal for handling sensitive or internal documentation securely.

## Who it´s for
- Professionals working with internal documents who need fast access to specific information.
- Support teams automating responses using technical or policy documentation.
- Developers building private chatbots without relying on public cloud-based LLMs.

## What the automation does
- Accepts PDF files via a form and extracts text using LangChain document loaders.
- Splits text into chunks and stores embeddings in a local Qdrant vector database via Ollama.
- On receiving a chat message, triggers a LangChain agent to perform semantic search over indexed content.
- Generates clear, context-based answers using the retrieved data.
- Supports dynamic updates to the knowledge base with new documents.
