🚀 Built for SLIIT students & beyond! This Retrieval-Augmented Generation (RAG) chatbot allows users to upload PDFs and ask AI-powered questions while ensuring answers are aligned with their specific documents.
During SLIIT semester exams, students face a major challenge: too many PDFs (lecture notes, past papers, textbooks) and inconsistent answers from AI tools like ChatGPT.
💡 The problem? University-specific content & approaches are different from generic AI responses.
✅ Solution: This chatbot retrieves answers directly from your uploaded PDFs, ensuring context-aware and accurate responses for study modules.
✅ Beyond education: Businesses & professionals can use it to query private documents (e.g., legal, financial, and policy documents) without exposing sensitive data to external AI models.
✔ Multi-PDF Upload 📂 – Upload multiple PDFs and get AI-driven responses based on their content.
✔ Image-Based Text Extraction (OCR) 📸 – Upload images (PNG, JPG, JPEG), and the chatbot extracts text using Google Vision API.
✔ RAG (Retrieval-Augmented Generation) 🔎 – AI retrieves answers directly from PDFs for contextually accurate responses.
✔ FAISS Vector Search ⚡ – Fast & efficient document retrieval.

Why not use ChatGPT for this? Because most company data is private, and generic AI cannot access or answer based on your internal documents. This chatbot keeps everything secure while enabling intelligent document search.
