- Clean, sticky UI with full chat history
- Runs 100% free using lightweight Hugging Face models

💡 How It Works
- Upload your PDF
- App chunks & embeds the text
- Uses FAISS to retrieve context
- Hugging Face model generates answers:
- Uses the doc context if available
- Falls back to general QA
- Refuses to answer if uncertain
