I've just built a fully local Q&A chatbot for PDFs - and it’s entirely offline. No cloud dependencies, no API keys, just open-source Generative AI that runs on your machine, giving you complete control and privacy.

### Why this matters

With growing concerns over data security and AI model transparency, many organisations want the power of modern AI without handing over sensitive documents to third-party APIs or cloud services. This solution gives you exactly that - all the benefits of retrieval-augmented generation (RAG), running locally.

### What’s under the hood?

- **Ollama** - easily run large language models like LLaMA or Mistral locally.
- **Sentence embeddings + vector search** - to find relevant context fast.
- **Streamlit** - for a clean, responsive user interface.
- **Full RAG pipeline** - document parsing, context retrieval, and generation - all handled securely on-device.

### What can you do with it?

Just upload a PDF and start asking natural language questions. Whether it’s internal documentation, research papers, or archived reports, this chatbot turns static files into interactive knowledge.

It’s perfect for:

- teams handling sensitive data
- research-intensive roles
- organisations exploring private GenAI solutions.

### Try it yourself

I’ve written a step-by-step guide with full code to get you started. Check out the full [blog tutorial and GitHub repo](https://github.com/ninadk10/pdf_qa_chatbot).
