Chat with PDF — RAG System

Chat with Your PDF is an end-to-end question-answering project built in Google Colab. It lets users upload a PDF document and ask questions about its content in natural language. The system retrieves the most relevant passages from the document and uses an open-source large language model, Qwen2.5, to generate accurate, grounded answers.

The entire pipeline runs locally inside Colab. It requires no paid API, no external services, and no API keys, which makes it free, private, and easy to reproduce.
